How the Department of Labor creates these projections

Step 1: Project industry employment

Data from the Quarterly Census of Employment and Wages are used to determine the number of jobs for each industry during the first year, or “base year” of the projection period. Certain types of public-sector employment – such as education, hospitals, rail transportation, and U.S. Postal Service – are combined with employment in private-sector industries.

The department creates projections for each industry based on historical trends and expected economic changes, Alaska and U.S. population projections, and other industry-specific variables. The projections also take into account any knowledge of specific projects and observations of the current economic climate.

Step 2: Determine the occupational makeup, or “staffing pattern,” of each industry

To estimate base year employment for each occupation, the department determines the occupational “staffing pattern” of each industry. Most industries have a wide variety of occupations. The staffing pattern is the breakdown of each occupation’s share of the industry’s total employment, referred to as “staffing ratios.”

Employers in Alaska report the occupations of their workers when they submit their unemployment insurance quarterly contributions report. The reported occupations are the basis of Alaska’s Occupational Database (ODB). We use an analysis of ODB data that corresponds to the projections’ base year, the most recent Occupational Employment Statistics data, available, and a baseline of historic industry staffing patters to calculate occupational staffing ratios for the industries. Since the ODB does not include federal government workers, staffing ratios were developed using occupation data from public and private industries closely related to individual federal divisions or agencies. For example, for civilian employment from army commissaries, staffing patterns for Other General Merchandise Stores (NAICS 452900) was used. Anecdotal information or survey data was also used as available.

Step 3: Calculate base year and projected occupational employment

For each occupation, the department multiplies each industry’s estimated base year employment by the staffing ratio, then sums the results to get the base year estimate.

For the projections, adjustments to staffing ratios within an industry are called “change factors.” Change factors are multipliers that increase or decrease an occupation’s estimated share of industry employment based on factors other than an industry’s projected employment change. Some examples are changes in consumer demands, technology, or business practices.

Each industry’s projected employment is then multiplied by the adjusted staffing ratio for each occupation, with the results summed by each occupation to get the projections. For more information on separations visit: Bureau of Labor Statistics

Step 4: Estimate job openings

Job openings for an occupation result from both job growth and occupational separations. An occupation’s growth openings are equal to its positive change over the projection period. Estimates of separation openings are based on rates provide by the Bureau of Labor Statistics that account for labor force exits and occupational transfers.
