Washington County's February unemployment rate of 5.6 percent was barely changed from January, according to the Maryland Department of Labor, Licensing and Regulation.
The county's jobless rate was up from January's rate of 5.5 percent.
The rate in Frederick County, Md., also went up slightly, from 4 percent to 4.3 percent.
Despite the slight increase, the unemployment picture in the county and statewide looks better than it did a year ago, when Washington County had 6.3 percent unemployment and Frederick County had 5 percent unemployment.
This mirrored the statewide trend.
Maryland's unemployment rate in February was 5.2 percent, unchanged from January.
Post-holiday layoffs in retail establishments and seasonal reductions in construction were offset by recalls in manufacturing and education, the state unemployment office said.
"We are optimistic that the mild winter weather may help moderate seasonal employment reductions in certain industries, which could favorably influence employment opportunities as spring approaches," said Secretary Eugene A. Conti Jr.
