Occupational Requirements Survey

Understanding ORS Series IDs: A guide to series ID usage and formatting

When working with data from the Occupational Requirement Survey (ORS), each series available will be assigned a specific series ID code. These codes are 20 digits long with each part corresponding to a feature of that series. Using the codes listed below, users can put together each portion of any series ID used in the ORS.

Understanding the different components of series IDs allows users to quickly find series using the Series ID shortcut, create custom database query code using the BLS Public Data API, and reference IDs in existing literature. Series ID codes are used for more programs than the ORS; the Series ID Format page contains information on each ID format used by any BLS program.

ORS Series ID Graphic

 

  1. Publication Prefix (AA) ▸
    • Every BLS database uses a unique prefix to identify the specific publication. ORS Series are labeled as either OR or OA. The OR prefix is used for the most recently published ORS dataset (including preliminary estimates). The OA prefix is used for the final second wave ORS dataset, which contains final estimates with a reference year of 2023. Other series ID prefixes can be found on the Series ID Format page.
  2. Seasonal Adjustment (B) ▸
    • The ORS does not contain any seasonally adjusted series so this code will always read “U” for not seasonally adjusted.
  3. Requirement (C) ▸
    • The Occupational Requirements Survey elements are grouped into four main categories: physical demands (P), environmental conditions (E) under which the work is typically performed, cognitive and mental requirements (C), and education, training, and experience (V). Response rates (R) are also available.

  1. Ownership (D) ▸
    • Indicates the sector for which the estimates represent. All workers covered by the ORS are referred to as civilian workers. Civilian workers include private industry and state and local government workers.

  1. Industry (EEEE) ▸
    • Sampled establishments are classified into industries using the North American Industry Classification System (NAICS). ORS estimates are not published at this level of detail, so all industry codes are assigned “All workers”.

While it is easy to break series down like this, it’s also important to know that not all combinations of series ID codes will result in a published series. Some estimates are only available for certain occupations, requirements, or simply not collected.

Example

We can put together an example pulling from the components above; let’s make the ID for the percent of civilian workers in management occupations; minimum education level is a high school diploma in education, training, and experience for all workers:

OAUV1000027P00000076

OA: ORS - final second wave dataset

U: Not seasonally adjusted

V: Education, training, and experience

1: Civilian workers

0000: All workers

27P: Management occupations

000: All workers

00076: Percent of workers, minimum education level is a high school diploma

For More Information

Each BLS series has a unique series ID, and while many have the same components, most have different codes. To find a series ID format for a different BLS program, see the Series ID Format page.

For more information on the Occupational Requirement Survey (ORS): data can be found in the ORS complete dataset or through the database search tools, factsheets provide information on key concepts, and the Handbook of Methods can provide more information on the ORS survey such as key terms, data sources and confidentiality, survey design, and calculation methodology.
