If we want to build authentic evidence-based policy, we need a strong descriptive foundation of evidence on the everyday experience of poverty. The National Poverty Study (NPS), which is currently in development, provides this foundation with a new “qualitative census” of the everyday conditions of poverty in rural, suburban, and urban sites. The NPS will allow us to build new evidence-based theories of poverty, evaluate and improve existing place-based antipoverty policies, validate official poverty measures, and assist local communities in improving the safety net for vulnerable populations.
