OKLAHOMA CITY (AP) — Oklahoma's treasurer says state revenue declined for the 18th consecutive month in August as unemployment in Oklahoma exceeded the national rate for the first time in 26 years.

Treasurer Ken Miller said Tuesday that gross receipts to the state treasury were down 4 percent last month compared with the same month last year. Collections during the past 12 months were off by more than 7 percent compared with the prior period.

Meanwhile, the Oklahoma Employment Security Commission says the state's unemployment is 5 percent, higher than the national rate of 4.9 percent in July. Miller says the last time Oklahoma's jobless rate topped the nation's was October 1990.

Miller says that two revenue sources — individual income and motor vehicle taxes — were each around 5 percent higher than in August 2015.
