The State of Economic Inclusion Report 2021 sheds light on one of the most intractable challenges faced by development policy makers and practitioners: transforming the economic lives of the world’s poorest and most vulnerable people. Economic inclusion programs are a bundle of coordinated, multidimensional interventions that support individuals, households, and communities so they can raise their incomes and build their assets. Programs targeting the extreme poor and vulnerable groups are now under way in 75 countries. This report presents data and evidence from 219 of these programs, which are reaching over 90 million beneficiaries. Governments now lead the scale-up of economic inclusion interventions, often building on preexisting national programs such as safety nets, livelihoods and jobs, and financial inclusion, and 93 percent of the total beneficiaries are covered by government programs. The report offers four important contributions: • A detailed analysis of the nature of these programs, the people living in extreme poverty and vulnerability whom they support, and the organizational challenges and opportunities inherent in designing and leading them. • An evidence review of 80 quantitative and qualitative evaluations of economic inclusion programs in 37 countries. • The first multicountry costing study including both government-led and other economic inclusion programs, indicating that programs show potential for cost efficiencies when integrated into national systems. • Four detailed case studies featuring programs under way in Bangladesh, India, Peru, and the Sahel, which highlight the programmatic and institutional adaptations required to scale in quite diverse contexts. Data from the report are available on the PEI Data Portal (http://www.peiglobal.org), where users can explore and submit data to build on this baseline.
