US Poor Gain Wealth... If They Behave

From the essay:

For the most part, long-term poverty today is self-inflicted. To see this, let's examine some numbers from the Census Bureau's 2004 Current Population Survey. There's one segment of the black population that suffers only a 9.9 percent poverty rate, and only 13.7 percent of their under-5-year-olds are poor. There's another segment of the black population that suffers a 39.5 percent poverty rate, and 58.1 percent of its under-5-year-olds are poor.

Among whites, one population segment suffers a 6 percent poverty rate, and only 9.9 percent of its under-5-year-olds are poor. Another segment of the white population suffers a 26.4 percent poverty rate, and 52 percent of its under-5-year-olds are poor.

What do you think distinguishes the high and low poverty populations? The only statistical distinction between both the black and white populations is marriage.
