The Census definition, or rate, determines poverty by comparing pretax cash income against a poverty threshold dollar amount that is adjusted for family size and composition.[1] In 2010, according to the official measure, 46.2 million people, or 15.1 percent of the total U.S. population, lived in poverty. This figure was up from 43.6 million people, or 14.3 percent, in 2009, making 2010 the fourth consecutive year that the official U.S. poverty rate has increased. Additionally,
2010 had the highest total number of people living in poverty in the 52 years that poverty estimates have been published.
