Following up on its September 16 release of national data on poverty in 2009 (which we analyzed here), the Census Bureau today released poverty data for the state and local levels showing that poverty rose in 31 states and fell in none. We analyzed the new data and found that the percentage of people in deep poverty — that is, with incomes below half the poverty line — rose by a statistically significant amount in 28 states in 2009. (See table.) It dipped in one state, Wyoming. Between 2000 and 2009, the share of the population living in deep poverty increased in 36 states.
Half of the poverty line corresponds to an income of $5,478 for an individual and $10,977 for a family of four.
The states with the highest rates of deep poverty in 2009 were Mississippi and Kentucky, where the shares of residents below half the poverty line were 9.3 percent and 8 percent, respectively. The state with the largest increase in deep poverty in 2009 was Colorado, where the deep poverty rate rose from 4.7 percent to 5.9 percent — an increase of more than one-fourth in a single year.
The earlier, nationwide Census figures showed that the number of people in deep poverty hit a record high in 2009, in data going back to 1975. Nineteen million people, or 6.3 percent of the population, were below half the poverty line in 2009, up 2 million from 2008. And 43.7 percent of poor people were below half the poverty line in 2009, also the highest on record.
Since the start of the recession in 2007, the number of people in deep poverty has risen 22 percent, even faster than the increase in regular poverty (17 percent).
Studies have found that deep poverty has a particularly strong effect on the education and development of young children. Even relatively small changes in incomes among low-income young children are associated with significant changes in school achievement.
