The state's jobless rate shot up two-tenths of a point last month, to 8.0 percent, driven largely by higher-than-expected seasonal layoffs in education.

Arizona lost 1,000 jobs in the private sector between May and June. But that's actually good news, compared with the 10-year average loss of 4,000 jobs for that time of year, said Aruna Murthy, director of economic analysis for the Arizona Department of Administration.

What skewed the numbers was the loss of 34,800 jobs in local education and another 11,100 jobs in state education. This sector of the economy loses jobs in June, as nonprofessional staff like cafeteria workers, custodians and bus drivers are laid off for the summer. But this year's figures are particularly high, Murthy said.

Overall, local education employment in June was 6,600 below its level a year earlier.

Arizona's jump in the employment rate comes as the national figure last month remained at 7.6 percent.

Overall the state's private sector economy was a mixed bag.

Employment in wholesale trade, such as warehouse workers, rose sharply, adding 3,100 jobs.

Retail employment also was up, by about 2,800, much of it due to hiring by car dealers, Murthy said. "People are buying cars," she said.

That trend also is reflected in sales tax data gathered by the state Department of Revenue. But Murthy cautioned there are indications interest rates are increasing, which could put monthly car payments out of range for some consumers.

At the other end of the spectrum, department stores and other general merchandise retailers are continuing to shed workers, dropping 400 between May and June. Employment in this sector is 1,100 below June 2012.

Murthy cited increases in Internet sales and changing technology as possible factors. Many stores have gone to self-checkout systems, with the customers scanning and bagging their own items. "So the number of people being hired in retail stores are fewer," she said.

Elsewhere in the economy, construction employment dropped by 500. But there are still signs of recovery, with the overall number of people working these jobs up 9,900 from a year ago.

Employment in health care also continues to increase, up 1,400 from May and 7,300 since last year.

But, not surprisingly for June, there were fewer people working in bars and restaurants than the month before. Still, overall employment is up 9,500 year over year.
