Silicon Valley, San Francisco, and Austin may grab lots of glory as American tech hubs, but Houston, Dallas, and San Antonio blast past all three of them in a new assessment of the top cities for tech workers.

Personal finance website SmartAsset combed through five data factors for 201 U.S. cities — average salary, average cost of living, concentration of tech employment, jobless rate, and average pay versus average tech pay — to come up with its 2018 ranking of the top U.S. cities for tech workers.

Houston comes in at No. 10, up from No. 15 in 2017. As SmartAsset points out, federal data shows the typical tech worker in Houston makes $94,200 a year — 75 percent more than the typical Houston worker.

"One concern, though, if you live in Houston — a bachelor's degree is no guarantee of employment," the report from SmartAsset says.

Why? About 3.6 percent of residents who have bachelor's degrees are unemployed, according to SmartAsset.

Dallas comes in at No. 3, and San Antonio ranks No. 8. Austin is No. 19 on the list, which is up from No. 20 last year.

Topping SmartAsset's ranking is Columbus, Ohio, followed by Des Moines, Iowa. It's worth noting that Silicon Valley and San Francisco didn't crack the top 25, thanks in large part to the high cost of living in that region.
