Unemployment dipped to a two-year low in March, but people with disabilities don’t appear to be sharing in the gains of the economy as a whole.

The unemployment rate among Americans with disabilities hit 15.6 percent in March, up just slightly from 15.4 percent the previous month, the Labor Department said Friday.

Meanwhile, the unemployment rate for the general population dropped to 8.8 percent from 8.9 percent as the economy added 216,000 jobs.

The Department of Labor began tracking employment among people with disabilities in October 2008. There is not yet enough data compiled to establish seasonal trends among this population, so statistics for this group are not seasonally adjusted.

Data on people with disabilities covers those over the age of 16 who do not live in institutions. The first employment report specific to this population was made available in February 2009. Now, reports are released monthly.
