赤貧
Median inflation-adjusted ("real") household income generally increases and decreases with the business cycle, declining in each year during the periods 1979 through 1983, 1990 through 1993, 2000 through 2004 and 2008 through 2012, while rising in each of the intervening years. Extreme poverty in the United States, meaning households living on less than $2 per person per day before government benefits, more than doubled in absolute terms from 636,000 to 1.46 million households (including 2.8 million children) between 1996 and 2011, with most of this increase occurring between late 2008 and early 2011.
