Occupational Wages - Technical Notes

Survey Based

The occupational wage data contained on this website were collected through the Occupational Employment and Wage Statistics (OEWS) survey, conducted by the Labor Market Information Center in cooperation with the U.S. Bureau of Labor Statistics (BLS).

The OEWS wage survey is based on a three-year data collection cycle; surveys are sent twice a year to capture data for second quarter and fourth quarter reference periods. Survey recipients are scientifically selected based on business activity, geographic location and worker levels. Over the three-year survey cycle, more than 6,000 establishments in the state are contacted. South Dakota continually meets or exceeds the 75% response rate required by BLS.

The website contains combined data from the entire three-year survey cycle. Estimates produced using only one year of sample data would be subject to a higher sampling error (due to the smaller sample size). Estimates based on more than one year of data provide significant sampling error reductions (particularly for small geographic areas and occupations), and the multiple years of data allow for the production of estimates at finer levels of geographic and occupational detail. The older panels' wage data are adjusted to the current May reference period using a modeling procedure and data from the Employer Cost Index (ECI). The employment levels from the six panels are benchmarked to the average of the most current May and previous November employment.

Statistical Definitions

Published occupational statistics include the estimated number of workers, average wage and percentile wage data. Data is published only if confidentiality and statistical reliability criteria are met. Per federal regulations under the Confidential Information Protection and Statistical Efficiency Act (CIPSEA), LMIC cannot provide data if there is a risk of employer identification. Wage data is initially viewed in the database as hourly rates, although an option is available to display the annual rates as well. Please note that hourly data is not available for some occupations, such as teachers. Workers in these occupations generally do not work the norm of 2,080 hours per year, and pay is usually based on an annual amount. Therefore, wages for these occupations are available only as annual salaries.

For certain entertainment occupations, only hourly wage data is available. There is a wide variation in the number of hours worked by those employed as actors, dancers, musicians and singers. Many jobs are for a duration of one day or one week and it is extremely rare for a performer to have guaranteed employment for a period that exceeds three to six months.

Mean/Average Wage: represents the arithmetic mean of the wage data collected, calculated by dividing the estimated total wages for an occupation by the number of workers in that occupation. The mean wage is also referred to as the average wage.

Percentile Wages: represents the percentage of an occupation's workers who earn less than or equal to that wage. For certain occupations, the upper percentile wages may not be available because of disclosure concerns or reliability issues. The following percentile wages represent distinct measures of the entire wage range:

10th Percentile: 10% earn less than or equal to this amount; 90% earn more

25th Percentile: 25% earn less than or equal to this amount; 75% earn more

50th Percentile: 50% earn less than or equal to this amount; 50% earn more (median wage)

75th Percentile: 75% earn less than or equal to this amount; 25% earn more

90th Percentile: 90% earn less than or equal to this amount; 10% earn more

Employment: represents an estimate of the total wage and salary workers employed in an occupation across all industries. For certain occupations, the number of workers statistic may not be available because of disclosure concerns or reliability issues.

Data Inclusions/Exclusions

Wages for the Occupational Employment and Wage Statistics (OEWS) survey are straight-time, gross pay, exclusive of premium pay. Base rate, cost-of-living allowances, guaranteed pay, hazardous-duty pay, incentive pay including commissions and production bonuses, and tips are included. Excluded are overtime pay, severance pay, shift differentials, nonproduction bonuses, employer cost for supplementary benefits, and tuition reimbursements.

About the Sioux Falls and Sioux City MSA data

Beginning with 2024 data, the Sioux Falls Metropolitan Statistical Area (MSA) is a cross-state MSA and includes Lincoln, Minnehaha, McCook and Turner counties of South Dakota as well as Rock County of Minnesota.

The Sioux City MSA is also a cross-state MSA including Union County in South Dakota, Plymouth and Woodbury counties in Iowa, and Dakota and Dixon counties in Nebraska. The Iowa Labor Market Information Division is responsible for gathering and compiling employment and wage data for the Sioux City cross-state MSA. Any questions regarding the Sioux City data should be directed to the Iowa Labor Market Information Division by calling 515.242.5862 or by visiting their website.

Differences Between South Dakota Data Published on this Website and South Dakota Data Published on BLS website

The BLS does not publish state occupational wage data on their website if the unrounded employment level in the occupation is less than 30. Since South Dakota is a small state and we make every attempt to publish wage data for as many occupations as possible, we publish data within our virtual labor market data system for small occupations (with unrounded employment less than 30) as long as the data meets data quality standards and confidentiality safeguards.
