Month-to-month declines were posted in the sectors of mining and logging; manufacturing; education and health services; and other services.
The mining and logging sector, which includes most oil and gas jobs, fell by 1,800 jobs for the month. The sector now accounts for 53,900 jobs, or about 3.3 percent of all jobs in Oklahoma.
Gray said the mining sector may be evening out after posting strong gains earlier in the year. He said lower prices for natural gas and decreased production also could be factoring into local employment levels.
Despite the monthly drop, the mining sector grew by 1,400 jobs, or 2.7 percent, since October 2011.
Overall, Oklahoma has added more than 42,200 jobs since October 2011, an increase of 2.7 percent. Manufacturing was among the best-performing sectors, adding 6,600 jobs in the last year to post an increase of 5.1 percent, the commission said. The trade, transportation and utilities sector grew by 4.2 percent and added 11,800 jobs in the last year.
