The rate for May was 5.7 percent, compared with 5.8 percent in April, the state Department of Economic and Employment Development reported last week.
Fifty-five fewer people were unemployed in the county in May than in April, the numbers show.
The county's jobless rate has been declining since February, when it was 8.5 percent.
A year ago in May, Carroll's unemployment rate was 5.1 percent, DEED reported.
Theodora Stephen, manager of the DEED office in Westminster, said the county has been lucky that its larger companies have not permanently laid off workers.
She said her office has been busy in the past week processing paper work for people eligible for the latest 13-week extension of federal unemployment benefits.
In Carroll, 3,644 people were unemployed in May, compared with 3,699 in April, DEED reported.

Maryland's unemployment rate increased for May to 6.7 percent, up from 6.6 percent for April, DEED reported. In May, 5,094 more people were unemployed in the state than in April.
More people entering the labor market to look for summer jobs caused the increase, a state official said.
"The increase in Maryland's jobless rate was mainly caused by the entry of students and other summer job-seekers into the labor force, a typical occurrence for this time of year," DEED Secretary Mark L. Wasserman said.
"The good news is that hiring has increased and unemployment insurance claims are declining."
The number of jobs in trade, construction and service industries has increased, according to DEED.
May was the third consecutive month that the state's jobless figure rose, DEED reported.
Across the state, jobless rates ranged from 3.7 percent in Montgomery County to 15.4 percent in Garrett County.
The U.S. unemployment rate for June was 7.8 percent, an increase from May's rate of 7.5 percent. (U.S. numbers are one month ahead of state numbers.)
