Since President Lyndon B. Johnson launched the War on Poverty 50 years ago, the characteristics of the nation’s poor have changed: A larger share of poor Americans today are in their prime working years and fewer are elderly. In addition, those in poverty are disproportionately children and people of any age who are black, Hispanic or both.

But perhaps just as striking is that the geographic distribution of the poor has changed dramatically, too. A new Pew Research Center analysis of U.S. Census Bureau data finds that the South continues to be home to many of America’s poor, though to a lesser degree than a half-century ago. In 1960, half (49%) of impoverished Americans lived in the South. By 2010, that share had dropped to 41%.

Much of the geographic shift of poverty reflects general trends in population shifts across the country over that same period. As rural areas, such as in the Midwest, have become less impoverished since the 1960s, those areas make up a smaller share of the U.S. population overall. At the same time, urban centers have gained in total population and hold a greater share of the U.S. population overall.
