In 2012, union members accounted for 7.5 percent of wage and salary workers in Oklahoma compared with 6.4 percent in 2011, the U.S. Bureau of Labor Statistics reported today. Regional Commissioner Stanley W. Suchman noted that the union membership rate for the state was at its peak in 1996, when it averaged 10.4 percent, and was at its low point in 2005 at 5.4 percent. (See chart 1.) Nationally, union members accounted for 11.3 percent of employed wage and salary workers, down from 11.8 percent in 2011. Since 1989, when comparable state data became available, Oklahoma union membership rates have never exceeded the U.S. average.

Oklahoma had 115,000 wage and salary workers who were union members in 2012. Additionally, another 25,000 workers in the state were represented by a union on their main job or covered by an employee association or contract while not being union members themselves. (See table A.) Nationwide, 14.4 million wage and salary workers were union members in 2012 and 1.6 million wage and salary workers were not affiliated with a union but had jobs covered by a union contract.

In 2012, 19 states had union membership rates above the U.S. average, of which 9 had rates above 15 percent. (See table 1.) Of the nine states with the highest rates, five were located in the West, three in the Northeast, and one in the Midwest. (See chart 2.) New York had the highest rate at 23.2 percent, followed by Alaska (22.4 percent), Hawaii (21.6 percent), and Washington (18.5 percent). In fact, New York has had the highest membership rate in the nation for 16 of the past 18 years.

Thirty-one states and the District of Columbia had union membership rates below the national average of 11.3 percent in 2012. Eight of these states had union membership rates below 5.0 percent with North Carolina having the lowest, 2.9 percent. The next lowest rates were recorded in Arkansas (3.2 percent) and South Carolina (3.3 percent). With the exception of Idaho, states with the lowest union membership rates were located in the South.

About half of the 14.4 million union members in the U.S. lived in just seven states (California, 2.5 million; New York, 1.8 million; Illinois, 0.8 million; Pennsylvania, 0.7 million; and Michigan, New Jersey, and Ohio, 0.6 million each), though these states accounted for only about one-third of wage and salary employment nationally.

State union membership levels depend on both the union membership rate and the employment level. For example, despite having nearly 250,000 fewer wage and salary employees statewide, Oklahoma had twice as many union members as South Carolina. North Carolina and Hawaii had comparable numbers of union members (112,000 and 116,000, respectively), though North Carolina's wage and salary employment level (3.8 million) was more than seven times that of Hawaii (537,000).

Technical Note

The estimates in this release are obtained from the Current Population Survey (CPS), which provides the basic information on the labor force, employment, and unemployment. The survey is conducted monthly for the Bureau of Labor Statistics by the U.S. Census Bureau from a scientifically selected national sample of about 60,000 households. The union membership and earnings data are tabulated from one-quarter of the CPS monthly sample and are limited to wage and salary workers. All
self-employed workers are excluded.

Union membership data, particularly for levels, are not strictly comparable for earlier years because of the introduction of updated population controls used in the CPS. For technical documentation and related information, including reliability of the CPS estimates, see www.bls.gov/cps/documentation.htm.
