Why are There So Many Manufacturing and Industrial Jobs in Tulsa, OK?

"How did Tulsa cement itself as a major manufacturing hub? What influenced most jobs in Tulsa, OK to land in the industrial sector? Oil and Planes The oil rush had its own contribution in shaping America. Long before the state of Oklahoma was born, the Glenn Pool was discovered. Today, it's a city 15 miles south of Tulsa; back in 1905, more than 120,000 barrels of black gold determined Tulsa's destiny as an industrial economy. These reserves were easy to harvest using oil drilling equipment of the time."

Companies Urged to Make Blue-Collar Tulsa Jobs a Thriving Gold Mine

"This is what the Tulsa Regional Chamber of Commerce, in coordination with various consulting agencies, found out in its workforce analysis report. Tulsa's job market growth (4.2 percent) is slightly below both federal (4.6 percent) and state (4.7 percent) market growth. West Tulsa jobs saw the most growth between 2010 and 2013 at 9.9 percent. Although unemployment rates continue to drop in many states including Oklahoma, experts see another problem. Most of the growing sectors include manufacturing, construction, and other blue-collar jobs, which is a given considering Tulsa's manufacturing economy. Despite a strong outlook, however, most people either don't have the right skillset or don't like the job at all."
