The number of "working poor" in the United States was 10.5 million in 2013. The working poor are people who spent at least 27 weeks in the labor force during the year—either working or looking for work—but whose incomes were below the official poverty level. The working-poor rate, or the ratio of the working poor to all those in the labor force for at least 27 weeks, was 7.0 percent in 2013.
In 2013, the number of women classified as working poor (5.4 million) was higher than that of men (5.0 million). Similarly, the working-poor rate continued to be higher for women (7.8 percent) than for men (6.3 percent).
Blacks and Hispanics were more than twice as likely as Whites and Asians to be among the working poor. In 2013, the working-poor rate was 13.3 percent for Blacks, 12.8 percent for Hispanics, 6.1 percent for Whites, and 4.5 percent for Asians.
