In the last year, Wyoming has seen an increase in industrial employment by 1.2 percent as the state now accounts for 1,200 manufacturers and 33,463 workers, according to the 2013 Wyoming Manufacturers Directory, an industrial directory published annually by Manufacturers’ News Inc. in Evanston, Ill.

Based on this percentage, Wyoming added 640 manufacturing jobs between October 2011 and October 2012.

“Wyoming has perhaps the nation’s most favorable tax structure for businesses and has enjoyed an energy boom in recent years,” says Tom Dubin, president of MNI. “The state’s significant oil, gas and coal extracting industries have led the way in the creation of new jobs.”

All of Wyoming’s largest industrial sectors by employment experienced employment gains from last year, MNI reports. In fact, oil and gas extraction, which has the most industrial employment, accounts for 10,219 jobs, an increase of 6.3 percent. Coal mining comes in second second with 6,431 jobs, a gain of 0.5 percent. Meanwhile, industrial machinery and equipment, the third-ranked sector, has 3,707 jobs, up 4.2 percent.

Of the remaining industrial sectors that added jobs are stone, clay and glass at 5.1 percent and electronics at 4 percent, MNI finds. Industrial sectors that saw losses are rubber and plastics at minus 18 percent, printing and publishing at minus 8 percent, fabricated metals at minus 7 percent, textiles and apparel at minus 6.5 percent, and lumber and wood at minus 5.3 percent.

Gillette continues to rank as the top Wyoming city for manufacturing employment with 6,058 jobs, a 1.5 percent increase, MNI finds. Second-ranked Casper is home to 4,276 jobs, marking a decrease of 0.5 percent, while Wright follows with 3,237 jobs. Next is Rock Springs with 2,663 jobs for no significant change, and Green River accounts for 2,481 jobs, a gain of 1.4 percent.
