Fifty years ago today, President Lyndon Johnson stood before Congress and declared an “unconditional war on poverty in America.” His arsenal included new programs: Medicaid, Medicare, Head Start, food stamps, more spending on education, and tax cuts to help create jobs.

At the time, 1 in 5 Americans was poor. Today, things are better, but tens of millions of Americans are still living at or below the poverty level. That raises the question: Did the war on poverty fail? In the coming year, NPR will explore this question and others about the impact and extent of poverty in the U.S., and what can be done to reduce it.
