Occupations are based on the Standard Occupational Classification system. An asterisk (*) next to an occupation title indicates the occupation has the same title but not necessarily the same content as an 2010 SOC occupation. For more information about the occupational classification used in 2011, see the Frequently Asked Questions (FAQ). For definitions of any occupation, or a more complete profile, see www.bls.gov/oes/current/oes_stru.htm.
A location quotient is a measure of the prevalence of an occupation in an area relative to the US average. It is the ratio of the share of an occupations local area employment to its share of U.S. employment. A location quotient greater than one indicates the occupation has a higher share of employment than average, and a location quotient less than one indicates the occupation is less prevalent in the area than average. For example, an occupation that makes up 2 percent of an areas employment, but only 1 percent of U.S. employment will have a location quotient of 2.
Industry data is based on the North American Industrial Classification System (NAICS). Charts use OES data for NAICS sectors and 4-digit industries. Charts show the largest 10 occupations for each industry. For a more complete occupational profile of any industry, including wages, in sortable tables go to www.bls.gov/oes/current/oessrci.htm. OES data is also available for 3-digit NAICS industries and for selected 5-digit industries for a total of almost 500 industries.
Data values that are illustrated in the charts can be seen by hovering over the bars within the charts. They can also be exported to Excel files. Data values in maps can be obtained by hovering over the state or area. Data for almost 600 areas is available in downloadable Excel files at www.bls.gov/special.requests/oes/oesm11ma.zip.
Metropolitan areas are metropolitan statistical areas or metropolitan divisions as defined by the Office of Management and Budget. The non-metropolitan areas are counties or combinations of counties in the balance of each state. There may be up to 6 nonmetropolitan areas in each state. A list of the metropolitan and nonmetropolitan area definitions can be found at www.bls.gov/oes/current/msa_def.htm
Navigation. Many charts have two drop down menus to help you isolate a detailed industry or detailed occupation. To find data for a detailed industry or occupation, select the sector or group in the first drop down menu and then select the detail from the second drop down menu.
Employment is the number of people working in the occupation in the area or industry.
Wages in the charts and maps refer to mean hourly wages for most occupations. For some occupations that do not work full time year round such as teachers and pilots, annual mean wages are presented. More wage information, including medians and 10th, 25th, 75th and 90th percentiles is available in other formats. The percentile data give a wider view of the range of wages in each occupation or area or occupation and industry.
Acknowledgements The information in these maps and charts is possible through the cooperation of more than a million business establishments that provide information on their workers to their state workforce agency and the U.S. Bureau of Labor Statistics (BLS). State workforce agencies within each state collect and verify almost all data provided. BLS selects the sample, produces the estimates, and provides technical procedures and financial support to the states. BLS also collects a small portion of the data from employers. The charts and maps were designed and created by Benjamin Cover, Chris Cunningham, David Tanner Beam, Stella Fayer, Laurie Salmon, and Jay McDaniel.
