Baby boomers retiring is my guess

A Tale of Two Jobs Markets looks at racial disparity in jobs.  But it may not be what it seems 

A striking picture of this lopsided reality is evident from the shares of the total job gains since the November 2007 pre-recession peak in employment. As the chart shows, of the five-million-plus net jobs added since that high-water mark nine years ago, some 56% went to Hispanics (rightmost green bar), about quadruple their 14% share of the labor force at the time (rightmost blue bar). Meanwhile, 29% of those job gains went to Asians, i.e., about six times their 5% share of the labor force (second set of bars from left). Moreover, 25% of those job gains went to Blacks, i.e., more than double their 11% share of the labor force (third set of bars from left).
In sharp contrast, Whites, who made up over 81% of the labor force in 2007 (leftmost blue bar) accounted for negative 9% of the net job gains (red bar). While the percentage shares for these four groups add up to more than 100% because White Hispanics are double-counted as both White and Hispanic, and Black Hispanics are double-counted as both Black and Hispanic, the reality is stark. Whites actually have fewer jobs than nine years ago, while Hispanics, Blacks and Asians together gained all of the net jobs added, and more.

This may be a case of baby boomers retiring, with few kids.
