Changes in DC

There's a piece in the Washingtonian on how the Obama administration changed Washington, DC.

Perhaps the single most telling stat on changes in DC during the past years is contained in this Post article on the stagnation in high school graduations.  There's a table with the data on VA, MD, and DC, showing a graph of rates from 2000 to 2031-2.  While white rates in both states are flat, the graph for white rates in DC soars above all others, reaching 500+ percent over 2000-1 by the end of the period.  (I'm guessing that the rate is already 200 percent of 2000-1, an increase paralleling the Hispanic increase, but the Hispanic rate levels off and then drops in the 2020's.)

Perhaps the Obama administration symbolized the demographic changes in DC, without actually causing them.
