How does women’s labor force participation differ across countries?

Women’s participation in labor markets differs across regions and countries

The chart shows that around half of all women worldwide are in the labor force but that this differs across world regions: while most are slightly or cleary above the global average, the Middle East and North Africa as well as South Asia have much lower participation rates.

Switching to the map view, we see that female labor force participation also differs a lot within world regions.

Men tend to participate in labor markets more frequently than women

Around the world, men tend to participate in labor markets more frequently than women. However, it only takes a glimpse of the data to see that there are huge differences across societies.

The map here provides a picture of how men and women compare today in terms of participation in labor markets, country by country. Shown is the female-to-male ratio in labor force participation rates (expressed in percent). These figures show estimates from the International Labor Organization (ILO). These are 'modeled estimates' in the sense that the ILO produces them after harmonizing various data sources to improve comparability across countries.

As we can see, the numbers for most countries are well below 100%, which means that the participation of women tends to be lower than that of men. Yet differences are outstanding: in some countries, the ratio is below 25%. In others, the ratio is close to, or even slightly above 100% (i.e. there is gender parity in labor force participation or even a higher share of women participating in the labor market than men).

Female labor force participation is highest in the poorest and richest countries

Female labor force participation is highest in some of the poorest and richest countries in the world. And it is lowest in countries with average national incomes somewhere in between. In other words: in a cross-section, the relationship between female participation rates and GDP per capita follows a U-shape. This is shown in the scatter plot here.

To highlight continents, you can click on the continent name tags on the right panel. If you do this you will see that some interesting patterns emerge. Within Africa, there is a negative correlation (the poorest countries have the highest participation rates), while in Europe there is a positive correlation (the richest European countries have the highest participation rates). Indeed, these correlations within high and low-income countries seem to explain a big part of the U-shape that appears in the cross-section.

Female labor force participation varies with age

The next chart compares labor force participation among younger and older women. To be specific, among women ages 25-34 and 45-54.

As we can see, very few countries lie on the diagonal line, so in most cases, female labor force participation is not constant across age groups.

In some countries, participation is higher for younger women, and in others, it is higher for older women. However, there is an interesting pattern: In countries where female participation in labor markets is generally low (those at the bottom left), it tends to be the case that participation is much higher among younger women.

How has women’s labor force participation changed over time?

Female participation in labor markets grew remarkably in the 20th century

The 20th century saw a radical increase in the number of women participating in labor markets across early-industrialized countries. The chart here shows this. It plots long-run female participation rates, piecing together OECD data and available historical estimates for a selection of early-industrialized countries.

As we can see, there are positive trends across all of these countries. Notably, growth in participation began at different points in time, and proceeded at different rates; nonetheless, the substantial and sustained increases in the labor force participation of women in rich countries remain a striking feature of economic and social change in the 20th century.¹

However, this chart also shows that in many rich countries – such as, for example, the US – growth in participation slowed down considerably or even stopped at the turn of the 21st century.²

Married women drove the increase in female labor force participation in rich countries

What do we know about the characteristics of the women who drove this remarkable historical expansion of female labor force participation in rich countries? As it turns out, the evidence shows that most of the long-run increase in the participation of women in labor markets throughout the last century is attributable specifically to an increase in the participation of married women.

As an example, the chart here shows female labor force participation rates in the US, by marital status.³ As we can see, the marked upward trend observed for the general female population is mainly driven by the trend among married women. Heckman and Killingsworth (1986) provide evidence of similar historical trends for the UK, Germany and Canada.⁴

Higher female labor force participation often went together with fewer worked hours

The charts above provide evidence regarding the expansion of female labor supply via higher participation rates. But this is of course only one way of measuring market supply. What about the number of hours worked? This is a relevant question since working hours for the general population decreased substantially in rich countries as they increased their productivity throughout the 20th century.

The chart here provides some clues. It shows several decades of changing average weekly hours worked for women in a selection of OECD countries. As we can see, most countries show negative trends, which is consistent with the trends for the population as a whole. However, some of these trends are still remarkable if we take into account the substantial increase in female participation taking place at the same time.

This is an important pattern: at the same time as more women in rich countries started participating in labor markets, there was often a reduction in the average number of hours that women spent at work.

The available evidence shows that overall the increase in supply of female labor was much larger than the decreased in the hours worked per woman. So in these countries, there was an increase in the sum of female worker hours – that is, the total yearly hours worked per female worker increased across all female workers.⁵

Female labor force participation worldwide is higher today than several decades ago

Looking at the more recent past and countries around the world, we see that the female labor force participation rate today is higher than several decades ago. This is true in the majority of countries, across income levels.

The chart here shows this, comparing national estimates of female participation rates in 1980 (vertical axis) and the most recent year (horizontal axis).⁶

The grey diagonal line in this scatter plot has a slope of one, so countries that have seen positive changes in female labor force participation rates appear below the line. As we can see, most countries lie on the bottom right. Indeed, in some cases, countries are very far below the diagonal line—in the United Arab Emirates, for example, there was a four-fold increase over the period.

On the aggregate, what does this imply for the global trend? The answer is not obvious, since some countries have missing data, and global trends are particularly sensitive to changes in large countries, such as India. Using statistical assumptions to impute missing data, the World Development Report (2012) estimates that in the period 1980-2008, the global rate of female labor force participation increased from 50.2 to 51.8 percent, while the male rate fell slightly from 82.0 to 77.7 percent. So the gender gap narrowed from 32 percentage points in 1980 to 26 percentage points in 2008.

An important point to note is that the chart includes all women above 15 years of age. This means that the trends conflate changes across different population sub-groups (e.g. young women, married women, older women above retirement age, etc.). We discuss this in more detail below.

The global expansion of female labor supply has come with an increase in the average age of women in the labor force

The next visualization shows the age distribution of women who are economically active worldwide.

As we can see, today the number of women in the global labor force who are younger than 25 is slightly less than what it was fifteen years ago. However, the global female labor force grew by almost 50% over the same period.

This shows that the global expansion of the female labor supply has come with an increase in the average age of women in the labor force.

In rich countries, there has been a steeper increase in the age of women in the labor force, partly because participation among younger women has actually gone down.

How does women’s labor force participation look like?

Types of labor force participation

We have already said that labor force participation is defined as being ‘economically active’. But what does that actually mean? Being able to answer this question is crucial to understanding changes in female participation in labor markets since women typically invest time in productive activities that do not count as ‘market labor supply’.

From a conceptual point of view, people who are economically active are those who are either employed (including part-time employment starting from one hour a week) or unemployed (including anyone looking for job, even if it is for the first time). Students who do not have a job and are not looking for one, are not economically active.

In the guidelines stipulated by the ILO, 'employment' also includes self-employment, which means that in principle, the labor force includes anyone who supplies labor for the production of economic goods and services, independently of whether they do so for pay, profit or family gain. The ILO shows an overview of what counts and what doesn’t towards producing 'economic goods and services'.⁷

Loosely speaking, the guidelines stipulate that unpaid activities should be excluded if they lead to services or goods produced and consumed within the household (and they are not the prime contribution to the total consumption of the household).⁸ This often means excluding unpaid work on things like "Preparation and serving of meals"; "Care, training and instruction of children"; or "Cleaning, decorating and maintenance of the dwelling". The implication, then, is that even if the guidelines are followed closely to include all possible forms of economic activities, even in the informal sector, there will still be an important number of 'working women' who are excluded from the labor force statistics. And these exclusions are even more salient if we consider that in many countries actual measurement deviates from the guidelines.

In many countries with poor capacity to produce national statistics, labor force participation is measured from population censuses, rather than from labor force surveys especially designed for that purpose.⁹ The consequence of this is that labor force statistics often exclude individuals who should be covered by the definitions above. Among the most important exclusions are workers engaged in unpaid work.¹⁰

Given all of this, it is natural to wonder if the 'key facts' would look different if we used an alternative definition of labor supply. Let's try to break down the figures to understand any relevant differences between 'labor supply' and other notions of 'work'.

Formal employment

The first and most obvious line splitting the economically active population in a country is employment. The chart here plots female employment-to-population ratios across the world (national estimates before ILO corrections). These figures show the number of employed women as a share of the total female population (in both cases, for women ages 15 or older).

To emphasize, here we are leaving aside unemployment, and we are focusing on trends for employed women – who are, by definition a subset of the whole economically active population.

As we can see, the trends are consistent with those for labor force participation: In the period 1980-2016, the majority of countries saw an increase in the share of women who are employed. This is what we would expect – it means that by and large, the participation of women in the labor market was driven by employment, rather than unemployment.

Female employment-to-population ratio using ILO modeled estimates

ILO modeled estimates provide a shorter time perspective, but are more accurate and complete.

Informal employment

Let us turn now to informal employment. As we mentioned above, the ILO guidelines stipulate that labor participation should include informal employment. So this is another important line that, in principle, cuts across the economically active population.

The first point to note is that, despite the guidelines, in practical terms work in the informal sector is not always reflected in labor statistics due to measurement issues. So an empirical study of economically active women in the informal sector remains a challenge. Nevertheless, some progress has been made on this front, and today many countries do report disaggregated figures for some forms of informal employment, mainly those relating to paid work in non-agricultural economic activities. (You can read more about measurement and definitions of informal employment in the ILO report "Women and Men in the Informal Economy: A Statistical Picture".) The chart shows these estimates.

The data shows that a large part of female employment around the world takes place in the informal economy. In fact, in low and middle-income countries, the vast majority of women engaged in paid work are in the informal economy.

In another interactive data visualization, you can see how the figures for women compare to those for men. The data suggests that in the majority of countries, women tend to work in the informal economy more often than men. It is likely that this gender difference would be larger if we accounted for the informal agricultural economy, for which data is not available. This is important because national sources of protection and support – as well as legal and policy frameworks – tend to favor formal workers.¹¹

Employment across sectors

The following chart plots the share of women in different economic sectors, country by country.

As we can see, in most countries there is 'occupational segregation': Women tend to be disproportionately concentrated in certain types of jobs. And in some cases (e.g. Italy in the chart), these patterns of segregation have become more pronounced in recent decades.

As we discuss elsewhere, this also has important consequences for pay differences between men and women.

Another way to explore segregation patterns is to cut the data the other way around, and look at the distribution of female employment across sectors. That is, the sectoral composition of female employment, rather than the gender composition of sectoral employment.

This can be seen in the charts for industry, services and agriculture.

All over the world men are more likely to work in industry than women (most countries lie below the diagonal line). And women tend to work more often than men in services.

The pattern for services is also interesting because it shows some important regional differences: In many low-income countries where the service sector is small in relative terms (i.e. countries in the bottom left, where both male and female employment in services is low), the pattern is reversed, and men tend to work more often in services than women. India is an important case in point.

Share of male vs female employment in agriculture

Unemployment

The next scatter plot looks at unemployment, and compares rates for men with those for women. As we can see, in most countries unemployment rates are higher for women than for men.

But the difference of the unemployment rates depends on the overall unemployment rate in the country:

On the left-hand side of the chart we can see that most countries lie close to the diagonal line marking gender parity. This means that in countries with generally low unemployment rates, the gender differences in unemployment are not very large.

However, on the right-hand side of the chart, most countries lie significantly above the diagonal line – so in countries where unemployment is more common, women tend to be disproportionately affected.

The map shows unemployment rates for women across the world. As we can see, the highest female unemployment rates correspond to the countries with the lowest female labor force participation, notably in North Africa and the Middle East.

Closely related to this is the fact that in many countries with low female labor force participation, people think that whenever jobs are scarce, men should have more rights to a job.

Unpaid work

Let us now have a look at unpaid work. As we have noted, domestic unpaid care work is an important activity on which women tend to spend a significant amount of time – and it is an activity that is typically unaccounted for in labor supply statistics. In the chart here we show just how skewed the gender distribution of unpaid care work in the household is.

The bars show the female-to-male ratio of time devoted to unpaid services provided within the household, including care of persons, housework and voluntary community work.

As we can see, gender differences in time devoted to unpaid care work cut across societies: All over the world, women spend more time than men on these activities.

Yet there are clear differences when it comes to the magnitude of these gender gaps. In some countries, women work around 70% more than men in unpaid care activities at home. In others, women work four or six times more than men on these activities.

Another chart provides a sense of perspective on the levels. In the MENA region, where the gap tends to be largest, women spend on average over 5 hours on unpaid care work per day, while men spend less than one hour.¹²

What affects women’s labor force participation?

In order to understand changing female labor force participation, it is important to first conceptualize the overarching context within which various factors operate. For women to be able to participate in the labor market, they have to have the time and opportunity to do so. This means that we can only fully analyze labor force participation if we understand time allocation more generally. In the case of female labor supply in particular, time allocation is crucially affected by the fact that women all over the world tend to spend a substantial amount of time on activities such as unpaid care work, which fall outside of the traditional economic production boundary. In other words, women often work but are not regarded as 'economically active' for the purpose of labor supply statistics.

Across all world regions, women spend more time on unpaid care work than men. On average, women spend between three and six hours on unpaid care work per day, while men spend between half an hour and two hours. If we consider the sum of paid and unpaid work, women tend to work more than men – on average, 2.6 extra hours per week across the OECD.

It is therefore not surprising that the factors driving change in female labor supply – whether they are improvements in maternal health, reductions in the number of children, childcare provision, or gains in household technology – all affect unpaid care work. Because time allocation is gendered in this way, female participation in labor markets tends to increase when the time cost of unpaid care work is reduced, shared equally with men, and/or made more compatible with market work.

Crucially, this analysis is not intended to diminish the importance of unpaid care work. On the contrary, such work is fundamental to – rather than separate from – economic activity and wellbeing, and the fact that it is omitted from national accounts is a point of debate.¹³

With this said, an obvious question remains: why do women perform a disproportionate amount of unpaid care work in the first place? As we discuss below, although time use should be a choice, evidence shows that social norms play a large part in determining gender roles and consequently, gendered time use.

Keeping this context in mind, let's have a look at the evidence behind the 'drivers' of rising female labor force participation.

Maternal health

The various aspects related to maternity – pregnancy, childbirth, and the period shortly after childbirth – impose a substantial burden on women's health and time. This, in turn, can have a significant impact on women's ability to participate in the labor force.

Before 1930, maternal mortality was the second biggest cause of death for American women in their childbearing years, claiming 850 deaths for every 100,000 live births in 1900. And for each such death, 20 times as many mothers experienced pregnancy-related health conditions which often included long-lasting or chronic disability.¹⁴ While maternal mortality has dropped to 10 deaths per 100,000 births across most rich countries, it is still comparatively high in poorer countries. Sub-Saharan Africa, for example, had a rate of 547 maternal deaths per 100,000 live births in 2015. For more information on maternal health, see our topic page on Maternal Mortality.

In a recent study, researchers Albanesi and Olivetti (2016)¹⁴ consider how improvements in maternal health between 1930 and 1960 contributed to rising female labor force participation in the US during that time period. Their approach is based on a calibrated macroeconomic model of household behavior. In other words, the authors incorporate numerical measures of medical progress into a quantitative model to assess the role of improving maternal health in accounting for the rise in labor force participation of married women in the US.

To measure 'medical progress', Albanesi and Olivetti draw on historical data and use it to estimate the burden of maternal conditions using the concept of 'disability-adjusted life years', or DALYs (you can find more details about this concept in our topic page on Burden of Disease). Their estimates suggest that the time lost to disabilities associated with maternal conditions declined from 2.31 years per pregnancy in 1920 to 0.17 in 1960. According to their model, the historical decline in the burden of maternal conditions and the introduction of infant formula can account for approximately 50 percent of the increase in married women’s labor force participation between 1930 and 1960 in the US.

The chart here plots US maternal mortality and female labor force participation as an index to their respective values in 1900 (thus 1900 = 100). As we can see, the correlation is stark: maternal mortality declined steeply between 1930 and 1960, while female labor force participation rose rapidly. Alternatively, you can see the data in a connected scatterplot.

The number of children per woman

On average, mothers around the world continue to spend more time on childcare than fathers. Because of this, fewer children per woman – lower fertility rates – can theoretically free up women's time and contribute to an increase in female labor force participation.

The chart here shows women’s fertility rate and female labor force participation across the world. Most countries are in the upper-left quadrant – that is, in most countries female labor force participation is high while fertility is low.

However, correlation is not the same as causation: a woman's choice to have fewer children might be influenced by the rising female labor force participation itself or other factors driving it. Instead, causal evidence can be found in studies that have identified exogenous – in other words, externally caused – changes in family size and measured their impact on labor market outcomes.

Some such studies provide evidence from twins, as conceiving twins can be seen as an unexpected increase in fertility.¹⁵ Other studies have considered women who sought medical help in achieving pregnancy. In those cases, fertility treatments create a 'control group' of women who were unable to become pregnant and a 'treatment group' of those who were able to get pregnant.¹⁶ And yet other studies have used country-level policies, such as abortion legislation, as an exogenous source of variation in fertility. When available, abortion can be seen as a way to avoid unwanted childbirth, and researchers argue that the timing of policy shifts making abortion legal and available is exogenous.¹⁷

In all of these studies, researchers find strong evidence of a causal link between higher fertility rates and lower labor market participation. In the most recent of the studies, Lundborg, Plug and Rasmussen (2017)¹⁸ find that women who are successfully treated by in vitro fertilization (IVF) in Denmark earn persistently less because of having children. This decline in annual earnings is explained by the fact that women tend to work less when their children are young and in turn get paid less when their children are older.

But of course, while 'exogenous variation' in the number of children per woman is an important way to establish causality, what actually matters is how women's control over their reproductive choices affects labor market outcomes. In their widely cited 2002 paper, "The Power of the Pill: Oral Contraceptives and Women's Career and Marriage Decisions", Goldin and Katz (2002) examine the behavioral effect of increasing women's control over their fertility.¹⁹ Their research shows how the diffusion of the birth control pill in the US during the late 1960s contributed to changing women's career and marriage choices by eliminating the risk of pregnancy, encouraging career investment, and "enabling young men and women to put off marriage while not having to put off sex."

Childcare and other family-oriented policies

The fact that falling fertility rates lead to higher labor force participation for women is certainly important from an empirical point of view. But it is obviously contradictory to promote female agency while suggesting women should have fewer children.

So it is helpful to consider other factors that make employment compatible with childbearing and thus broaden the choices available to women. Let's begin with childcare, parental leave, and other family-oriented policies.

While the years after World War II saw a rise in women’s labor force participation across every OECD country, growth in participation began at different points in time and proceeded at different rates in each country. In 2016, for example, Sweden’s female labor force participation rate was 70%, while it was only 56% in Germany and 40% in Italy. Researchers comparing broad policy configurations argue that the different types of welfare states that emerged in rich countries after World War II have contributed to these differences.²⁰

Social democratic policies such as those seen in Sweden, for example, are characterized by subsidized childcare, paid parental leave that is designed to encourage both mothers and fathers to participate in childcare, and support for full employment. Liberal welfare states, on the other hand, take a more hands-off approach to social policy – one prominent example is the US’s maternity leave.

In the chart here, we show that female employment, measured as the employment-to-population ratios for women 15+, tends to be higher in countries with higher levels of public spending on family benefits (i.e. child-related cash transfers to families with children, public spending on services for families with children, and financial support for families provided through the tax system, including tax exemptions).

While the pattern seen in this chart is only a correlation, evidence suggests that this relationship is in fact causal. A natural experiment from Canada, for example, provides compelling proof that childcare support can have a positive effect on the labor force participation rate of mothers with young children. In 1997, the provincial government of Quebec introduced a generous subsidy for childcare services, effectively imposing an exogenous reduction in childcare prices. Researchers Lefebvre and Merrigan (2008) found that this policy had substantial labor supply effects on the mothers of preschool children, both among well-educated and less well-educated mothers.²¹ In 2002, the policy increased the participation rate of mothers (with at least one child aged 1-5 years) by 8 percentage points, and their hours worked increased by 231 per year.

Labor-saving consumer durables

In 1890, only 24% of US households had running water. In 1900, 98% of households in the US washed their clothes using a scrubboard and water heated on a wood or coal-burning stove. It is not hard to see then why in 1900, the average American household spent 58 hours per week on housework. By 1975, that figure had declined to 18. Progress in labor-saving consumer durables in the household has thus been another factor contributing to the rise in female labor force participation, especially in early-industrialized countries. Of course, this is feasible especially because women – both in 1900 and now – take on a disproportionate amount of unpaid domestic work.

Greenwood et al. (2005) present evidence for this by calibrating a quantitative economic model to show that the consumer goods revolution – which, as we can see in the chart here, introduced washing machines, vacuum cleaners, and other time-saving products – can help explain the rise in married female labor force participation in the US.²²

It is important to know, however, that these improvements have not yet reached all households around the world. Hundreds of millions of people are still without access to improved water sources. A recent study by Graham, Hirai, and Kim (2016) looked at water collection in Sub-Saharan Africa – where it is estimated that more than two-thirds of the population must leave their home to collect water – and found that this time-consuming and physically grueling chore falls primarily to women.²³

Social and cultural factors

Some argue that there is a "natural" distribution of gender roles, with women being better suited to domestic and child-rearing responsibilities and men to working outside of the home. Such assertions lack compelling evidence and more importantly, perpetuate a status quo that limits the choices available to both men and women.²⁴ Instead, it is known that social norms and culture influence the way we see the world and our role in it. To this end, there is little doubt that the gender roles assigned to men and women are in no small part socially constructed.²⁵

To determine when and how existing gender norms first gained a foothold, researchers have attempted to connect historical evidence to modern norms and opinions.²⁶ For example, Alesina, Giuliano and Nunn (2013) contribute to the explanation of existing cross-cultural beliefs and values about the appropriate role of women in society by looking at the division of labor in the distant past.²⁷ They test the hypothesis that historically, societies that adopted plow-based agriculture, which required "significant upper body strength", gave men an advantage relative to women in a crucial aspect of production. They contrast such societies to those that employed 'shifting cultivation', which uses hand-held tools like the hoe, and in which women participated actively.

Their findings suggest that the division of labor that arose around plow use generated persistent cultural norms about the appropriate role of women in society, which norms have continued to exist at an individual level beyond agrarian economies and under different institutional structures. By comparing pre-industrial ethnographic data with contemporary measures of individuals’ views on gender roles across countries, ethnic groups, and individuals, they show that historical plow use has a positive statistical relationship with unequal gender roles today.

Another study published in the journal Science by Dyble et al. (2015), goes even further back in time, arguing that hyper cooperation among hunter-gatherers – an important characteristic that may serve to evolutionarily differentiate modern humans from our ancestors – was enabled by sex egalitarianism.²⁸ The study uses agent-based modeling to suggest that wealth and sex inequalities began to emerge when "heritable resources, such as land and livestock, became important determinants of reproductive success."

And while it is possible that socially-assigned gender roles emerged in the distant past, our recent and even current practices show that these roles persist with the help of institutional enforcement. Goldin (1988), for instance, examines past prohibitions against the training and employment of married women in the US.²⁹ She touches on some well-known restrictions, such as those against the training and employment of women as doctors and lawyers, before focusing on the lesser known but even more impactful "marriage bars" that arose in the late 1800s and early 1900s. These work prohibitions are important because they applied to teaching and clerical jobs – occupations that would become the most commonly held among married women after 1950. Around the time the US entered World War II, it is estimated that 87% of all school boards would not hire a married woman and 70% would not retain an unmarried woman who married.

Where are there restrictions on the jobs women are allowed to have?

The map here shows that to this day, legal barriers to female labor force participation exist in parts of the world. The data in this map provides a measure of whether there are any specific jobs that women are not allowed to perform. So, for example, a country might be coded as "No" if women are only allowed to work in certain jobs within the mining industry, such as health care professionals within mines, but not as miners.

But even after explicit barriers are lifted and legal protections put in their place, discrimination and bias can persist in less overt ways. Goldin and Rouse (1997), for example, look at the adoption of "blind" auditions by orchestras, and show that by using a screen to conceal the identity of a candidate, impartial hiring practices increased the number of women in orchestras by 25% between 1970 and 1996.³⁰

Public opinion about working women

In fact, discrimination and biases operate in many other ways, permeating all spheres of life. As the chart here shows, at the end of World War II, only 18% of people in the US thought that a wife should work if her husband was able to support her. Indeed, it is not surprising that around this time, female labor supply in market activities was low, and demand-side barriers were high. As this chart shows, female labor supply started increasing in the US alongside changing social norms: people's approval of married women working went up during a period of remarkable growth in female labor force participation and then flattened at around the same time that participation stalled. For more details on this see Fortin (2015) and Goldin and Katz (2016)³¹.

Social norms and culture are clearly important determinants of female labor force participation. So how can social norms be changed? Research in this area shows that social norms and culture can be influenced in a number of non-institutional ways, including through intergenerational learning processes, exposure to alternative norms, and activism such as that which propelled the women's movement.³²

Structural changes in the economy

Having now discussed the various determinants affecting women's labor force participation in the context of socially assigned gender roles, we turn to the larger picture. How do these pieces factor into a global landscape of varied income levels and changing economic conditions?

In low-income countries, where the agricultural sector is particularly important for the national economy, we see that women are heavily involved in production, primarily as family workers. Under such circumstances, productive and reproductive work is not strictly delineated and can be more easily reconciled. With technological change and market expansion, however, work becomes more capital-intensive and is often physically separated from the home. In middle-income countries, there is an observed social stigma attached to married women working and "women’s work is often implicitly bought by the family, and women retreat into the home, although their hours of work may not materially change."³³

With sustained development, women make educational gains and the value of their time in the market increases alongside the demand-side pull from growing service industries. This means that in high-income countries, the rise in female labor force participation is characterized by women gaining the option of moving into paid, often white-collar work, while the opportunity cost of exiting the workforce for childcare rises.³⁴

The chart here shows some evidence of this pattern. As we can see, female labor force participation is highest in some of the poorest and richest countries in the world, while it is lowest in countries with incomes somewhere in between. In other words: in a cross-section, the relationship between female participation rates and GDP per capita follows a U-shape.

Given that informal employment in the agricultural sector is typically not captured in labor statistics, the chart here offers only partial evidence of the mechanisms described above. However, multiple studies have found support of a U-shaped female labor supply function, both within and across countries over the course of development.³⁵
