In the first half of 2013, the U.S. oil and gas industry added 23,700 jobs, for a net growth rate of 2.4%. Between June 2012 and June 2013, industry employment grew by 2.6%, which was faster than the overall U.S. private sector. Moreover, during the past 18-months, from January 2012 to June 2013, the industry grew by as much as 5.7%, a figure that also topped the overall U.S. private sector. The majority of the growth in 2013 was concentrated in oil and gas extraction, drilling and support activities. Over the 18-month period, nearly half the employment growth for the oil and gas industry was driven by supporting activity, which added 26,900 jobs compared to the 54,900 jobs added for the entire oil and gas industry. A new report from the Texas Independent Producers & Royalty Owners Association (TIPRO) examines nine primary sectors comprising the U.S. oil and natural gas industry, revealing growth across all sectors for the first half of 2013 and ending June 30, 2013, with the exception of the oil & gas field machinery and equipment sector.
