The job market is roaring to highs not seen in decades, according to economic data that shows improvement week after week.

But the national numbers mask stark regional divides, according to an analysis out Thursday.

Jessica Rabe, co-founder of DataTrek Research, analyzed data from Google Trends, a tracker of what people all over the world are searching for. That tool offers what Rabe calls “a novel take on a two-speed job market.”

The two speeds, of course, are urban and rural.

The most search interest in “job openings” comes from southern or midwestern states like Mississippi, North Dakota, and Iowa, Rabe wrote, while the strongest interest in “jobs” comes from rural states like Virginia, New Mexico, and Alaska.

In contrast, the search term “ask for a raise” comes more from people in states like California, New York, Illinois, and Texas.

“Our takeaway,” Rabe wrote, is that “workers in large urban areas (who are statistically more likely to have a college degree) are asking for raises, while people in more rural areas are still searching for jobs.”

Rabe suggests this explainer on educational attainment of rural Americans, which the U.S. Department of Agriculture notes “has not kept pace with urban gains.”

It’s worth noting that trying to analyze complex economic shifts at the state level is often not much more granular than looking at the national picture. According to the Labor Department, in August many of the rural states Rabe mentioned had jobless rates well below some of the states where people felt confident enough to be asking for raises, not jobs.

State Unemployment rate, August 2017 Mississippi 5.3% North Dakota 2.3% Iowa 3.3% Virginia 3.8% New Mexico 6.3% Alaska 7.2% California 5.1% New York 4.8% Illinois 5.0% Texas 4.2%

The Labor Department also tracks annual changes in unemployment, at this colorful page, and there aren’t clear trends there either. In fact, some of the rural states have seen bigger declines than the urban ones.
