1998 Occupational Employment and Wage Estimates

Employment and Wage Estimates by Occupation

Tables for each area listed below have the following columns:

  • OES Code: a unique, five-digit numerical identifier for each OES occupation.
  • Occupation Title: a descriptive title that corresponds to the OES code.
  • Employment: the estimated total occupational employment (not including self-employed).
  • Median Hourly Wage: the estimated 50th percentile of the distribution of wages; 50 percent of workers in an occupation earn less than the median wage, and 50 percent earn more than the median wage.
  • Mean Hourly Wage: the estimated total wages of an occupation divided by its estimated employment.
  • Mean Annual Wage: the estimated mean wage of an occupation per year.
  • Relative Standard Error: the reliability or precision of mean wage estimates. The relative standard error is defined as the ratio of the standard error to the survey estimate. For example, a relative standard error of 10 percent implies that the standard error is one-tenth as large as the survey estimate.

OES occupational classification system

The 1998 OES Estimates are the last estimates produced using the OES occupational classification system. Begining with the 1999 estimates, the OES program began using the Standard Occupational Classification (SOC) system.

Revision Note

The 1998 OES estimates for California, the District of Columbia, and Oregon were revised to incorporate corrections to some of the occupational wage estimates. These changes, in turn, required a revision of the national wage estimates. The corrections were required for those States in which the State minimum wage over the three-year data collection period was significantly higher than the Federal minimum wage level. These corrections did not affect employment estimates.

Virtually all (99 percent) of the corrections to the Statewide and MSA-level wage estimates were within the published sampling error range for the estimate. While the majority of the changes were within a +/- 5 cents an hour range, there were some occupations with larger changes. The changes to hourly mean wage estimates at the statewide level ranged between an increase of 1 cent to an increase of 27 cents per hour for California; a decrease of 70 cents to an increase of 55 cents per hour for the District of Columbia; a decrease of $1.19 to an increase of 12 cents per hour for Oregon; and a decrease of 3 cents an hour to an increase of 14 cents per hour at the national level.

National Estimates by Occupation and Industry

National Employment and Wage Estimates are available at the 2- and 3-digit Standard Industrial Classification (SIC) industry level. The estimates, in XLS format, can be fownloaded from the OES download page.

1996, 1997, and 1998 respondent data

The 1998 estimates have a fourth-quarter 1998 reference period and are based on information from the 1996, 1997, and 1998 surveys. The 3 years of survey responses for employment and wage data have been combined to produce the 1998 results. The employment data from 1996, 1997, and 1998 have been adjusted to the full universe count for the 1998 survey reference period based on the Quarterly Census of Employment and Wages (ES-202) program. (Estimates for New Jersey were adjusted to second quarter 1998, since data for fourth quarter 1998 were unavailable.) The 1996 and 1997 wage data have both been adjusted to the 1998 reference period using the over-the-year wage change in the most applicable Employment Cost Index series.
