About 1.2 billion people worldwide live under less than 1.25 USD per day, and this coincides to about 17 percent of the world’s population. Multidimensional measures of poverty may indicate even higher levels of the world’s population facing different kinds of deprivation. The global poor define extreme poverty as a lack of food, a lack of access to infrastructure, being in poor health, being illiterate, and being without a voice. These deprivations, together, put people at a severe disadvantage and, therefore, constitute the multiple dimensions of poverty. Priority actions for poverty eradication include providing access to sustainable livelihoods and equal opportunities for those with lesser means and providing access to basic services such as education, health, and basic infrastructure. Development Analytics focuses on both the measurement of poverty and inequality as well as the evaluations of poverty alleviation and social protection programs under this work program. The measurement of multidimensional poverty, measurement of inequality of opportunities, the link between poverty and access to basic social services and the targeting, effectiveness, and impact of social protection programs are key components of research projects we have carried out in this field.
