Connecticut lost an estimated 1,500 jobs in October while an estimated gain of 3,600 jobs in September was revised upward by an additional 1,100 jobs, the state Labor Department reported Monday.

Over the year, nonagricultural employment in the state has grown by 4,800 jobs.

The state’s October unemployment rate remained at 3.6 percent, unchanged from the revised rate for September. The U.S. unemployment rate also is 3.6 percent.

“The October decline of 1,500 payroll jobs is the first (decline) we’ve seen since June and was particularly impacted by the loss of trade jobs,” Andy Condon, director of the department’s Office of Research, said in a statement.

Private sector employment fell by 1,000 jobs in October while the government sector — all federal, state and local employment, including public higher education and Native American casino employment on tribal land — lost 500 jobs.

Construction and mining added 700 jobs, the most of any industry “supersector,” followed by manufacturing, which added 500 jobs. Trade, transportation and utilities lost 1,000 positions, the biggest loss of any supersector.

Four of the state’s six labor market areas experienced job increases in October, led by the Norwich-New London-Westerly and Bridgeport-Stamford-Norwalk areas, each of which added 700 jobs. The Hartford area lost 1,200 jobs.
