A review of state data shows the counties with the most oil and gas production lag behind the rest of Ohio in terms of employment rates, according to Energy News Network.

Employment rates in Belmont, Carroll, Guernsey, Harrison, Jefferson, Monroe and Noble counties have fallen short of the state average every year since 2010. The data contrasts what supporters of the industry believed would happen — the shale boom would create jobs.

According to a report commissioned by the industry-funded Ohio Oil and Gas Energy Education Program, the shale industry was expected to create 204,000 jobs in Ohio as soon as 2015.

However, reports by the Ohio Department of Jobs and Family Services show a net increase of less than 21,000 jobs in core and supporting industries since 2012.
