Arizona's seasonally adjusted jobless rate ticked up a tenth of a point last month, to 5 percent, driven by weaker than normal growth in the private sector.
Companies added 10,300 jobs in August. That compares with an average gain of 15,600 during the past decade at this time of year.
The new numbers increase the difference between what's happening in Arizona versus the rest of the country, where the unemployment rate for August remained at 3.7 percent.
But Doug Walls, the labor market information director for the state's Office of Economic Opportunity said the overall economic situation remains good in Arizona, with the number of people in the labor force here up by 2.8 percent in the past year compared to 1.3 percent for the rest of the country.
As has been the pattern now for some time, retail trade remains weak, shedding another 1,100 jobs between July and August. Though, employment in transportation and warehousing -- including the e-commerce firms -- is up by 1,900.
Aside from the shift in consumer buying patterns, there may be another factor at work, particularly in the Tucson area: border politics.
"We are seeing weak retail job growth here in Pima County,'' said George Hammond, director of the Economic and Business Research Center at the Eller College of Management at the University of Arizona.
Part of that issue, he said, is likely related to the fact that it is more difficult for shoppers from Mexico to get across the border to make their purchases. Hammond said that is borne out by statistics showing that northbound crossings from Mexico into the United States have been "significantly slower.''
Mexican shoppers aside, Hammond said the fact remains that the growth rate in the Phoenix area, where three-fourths of the jobs are located, has historically been faster, driven by a more diverse economy.
The latest monthly report produced few surprises, with growth in most major economic sectors.
One outlier is construction, which lost 1,300 jobs between July and August.
That, however, could be a statistical aberration, as the industry has been showing strong and steady growth now for a while, with the number of people working in construction now up 9.5 percent from a year ago.
Manufacturing employment is up by another 300 in August, with a 5.4 percent year-over-year increase.
The new report also found that wages in Arizona in the past quarter are up 3.3 percent from the same time a year earlier.
That is less than the 3.5 percent figure for the nation. And it leaves the average hourly wage in Arizona at $26.54 compared with $27.89 nationally, nearly 5 percent lower.
Walls said none of this should be a surprise, pointing out that wages in Arizona have traditionally run behind the rest of the country. He said at least part of the factor is that the cost of living is lower in Arizona.
That, however, is subject to debate.
The web site BestPlaces, which provides advice to those seeking to move, finds the overall cost of living in Arizona is 12.4 percent higher than the national average.
In some areas, the web site reports, Arizona is close, with the cost of health care here less than 1 percent higher than nationally. But it finds transportation costs, including gasoline, car insurance and maintenance expenses, running 21 percent above the rest of the country.
And housing costs, covering both buying and renting, are more than 28 percent higher.
But USA Today, in a May 2018 story, found Arizona to have lower-than-average costs when all factors are combined. It concluded that what the average dollar could purchase nationally could buy $1.04 worth of goods and services in Arizona.
