Greg Mankiw notes:The standard story is that poverty is stuck; superficially, the statistics support that. The poverty rate measures the share of Americans below the official poverty line, which in 2006 was $20,614 for a four-person household. Last year, the poverty rate was 12.3 percent, down slightly from 12.6 percent in 2005 but higher than the recent low, 11.3 percent in 2000. It was also higher than the 11.8 percent average for the 1970s. So the conventional wisdom seems amply corroborated.
It isn't. Look again at the numbers. In 2006, there were 36.5 million people in poverty. That's the figure that translates into the 12.3 percent poverty rate. In 1990, the population was smaller, and there were 33.6 million people in poverty, a rate of 13.5 percent. The increase from 1990 to 2006 was 2.9 million people (36.5 million minus 33.6 million). Hispanics accounted for all of the gain.
Consider: From 1990 to 2006, the number of poor Hispanics increased 3.2 million, from 6 million to 9.2 million. Meanwhile, the number of non-Hispanic whites in poverty fell from 16.6 million (poverty rate: 8.8 percent) in 1990 to 16 million (8.2 percent) in 2006. Among blacks, there was a decline from 9.8 million in 1990 (poverty rate: 31.9 percent) to 9 million (24.3 percent) in 2006. White and black poverty has risen somewhat since 2000 but is down over longer periods.
Of course, many of these poor immigrants are nonetheless richer than they were in their country of origin.Great point. Mankiw also points out that immigration changes the population distribution in the US and affects statistics like median household income.
Bottom line: Improvements in poverty levels and increasing incomes in the US are typically under-reported and misrepresented because they are skewed by data that includes recent immigrant populations. Factoring this data out shows a much truer (and optimistic) outlook for improvements in American standards of living.
