[Excerpt] In 2013, 45.3 million people were counted as poor in the United States under the official poverty measure—a number statistically unchanged from the 46.5 million people estimated as poor in 2012. The poverty rate, or percent of the population considered poor under the official definition, was reported at 14.5% in 2013, a statistically significant drop from the estimated 15.0% in 2012. Poverty in the United States increased markedly over the 2007-2010 period, in tandem with the economic recession (officially marked as running from December 2007 to June 2009), and remained unchanged at a post-recession high for three years (15.1% in 2010, and 15.0% in both 2011 and 2012). The 2013 poverty rate of 14.5% remains above a 2006 pre-recession low of 12.3%, and well above an historic low rate of 11.3% attained in 2000 (a rate statistically tied with a previous low of 11.1% in 1973).
The incidence of poverty varies widely across the population according to age, education, labor force attachment, family living arrangements, and area of residence, among other factors. Under the official poverty definition, an average family of four was considered poor in 2013 if its pre-tax cash income for the year was below $23,834.
