The US poverty rate rose in 2010 to 15.1 percent, the highest rate since 1993, the Census Bureau reported Tuesday in another sign of a sputtering economy following a deep recession.
The report showed a sharp increase in poverty from 14.3 percent in 2009, and a fourth consecutive rise in the number of people below the poverty threshold, to 46.2 million.
The number of people in poverty was the highest since data collection began in 1959, although the rate was 7.3 percentage points lower than in 1959.
The US definition of poverty is an annual income of $22,314 for a family of four, and $11,139 for a single person in 2010.
The survey showed struggles for the rest of Americans, with median household income falling 2.3 percent to $49,445.
The Census Bureau also said the number of people without health insurance coverage rose to 49.9 million in 2010 from 49.0 million in 2009, while the percentage without coverage -- 16.3 percent -- was not statistically different from the rate in 2009.
The census report said there no "statistically significant" change in inequality between 2009 and 2010 based on its index.
The poverty rate for blacks and Hispanics was much higher than for the overall population at 25.8 percent and 25.3 percent, respectively. Among regions, the South had the highest poverty rate at 15.7 percent and the highest percentage without health insurance, 19.2 percent.
The report, showing the first full year since the recession officially ended in June 2009, supports the notion that Americans have been losing ground economically. It showed real median incomes fell 6.4 percent from pre-recession levels in 2007 and were 7.1 percent below the peak in 1999.
