Frequently Asked Questions
What is the International Poverty Line and how is it set?
There is no single definition of poverty. Our understanding of the extent of poverty and how it is changing depends on which definition we have in mind.
What are international-$ and why are they used to measure incomes?
Much of the economic data we use to understand the world – for instance on the goods and services bought or produced by households, firms and governments, or the incomes they receive – is initially recorded in terms of the units in which these transactions took place. That means this data starts out being expressed in a variety of local currencies – as so many rupees, US dollars, or yuan, etc. – and without adjusting for inflation over time. This is known as being in ‘current prices’, or in ‘nominal’ terms.
How comparable is the World Bank data on household incomes across time or between countries?
Because there is no global survey of incomes, researchers need to rely on available national surveys. Such surveys are designed with cross-country comparability in mind, but because the surveys reflect the circumstances and priorities of individual countries at the time of the survey, there are some important differences. In collating this survey data the World Bank takes steps to harmonize it where possible, but comparability issues remain.
How does the World Bank produce global and regional estimates of poverty and inequality from national data?
