Total Emp : Estimated total employment rounded to the nearest 10 (excludes self-employed).

‍Emp Prse  :   Percent relative standard error (PRSE) for the employment estimate. PRSE is a measure of sampling error, expressed as a percentage of the corresponding estimate. Sampling error occurs when values for a population are estimated from a sample survey of the population, rather than calculated from data for all members of the population. Estimates with lower PRSEs are typically more precise in the presence of sampling error.

‍Loc Quotient : The location quotient represents the ratio of an occupation’s share of employment in a given area to that occupation’s share of employment in the U.S. as a whole. For example, an occupation that makes up 10 percent of employment in a specific metropolitan area compared with 2 percent of U.S. employment would have a location quotient of 5 for the area in question.

Jobs 1000 :  The number of jobs (employment) in the given occupation per 1,000 jobs in the given area. Only available for the state and MSA estimates; otherwise, this column is blank.

A Mean : Mean Annual Wage

A Pct 10 : Annual wage 10 percentile

A Pct 25 : Annual wage 25 percentile

A Median :  Annual median wage (or 50th percentile)

A Pct 75 : Annual wage 75 percentile
