Important Information

Annual Revisions

Each year, historical estimates from the Local Area Unemployment Statistics (LAUS) program are revised to reflect new population controls from the Census Bureau, updated input data, and reestimation. The data for model-based areas also incorporate new seasonal adjustment, and the unadjusted estimates are controlled to new census division and U.S. totals. Substate area data subsequently are revised to incorporate updated inputs, reestimation, and controlling to new statewide totals.

Model-Based Areas

On March 4, 2020, the LAUS program issued 2019 annual-average civilian labor force and unemployment estimates for census regions and divisions; all states and the District of Columbia; the Los Angeles-Long Beach-Glendale, CA Metropolitan Division; the Miami-Miami Beach-Kendall, FL Metropolitan Division; the Chicago-Naperville-Arlington Heights, IL Metropolitan Division; the Detroit-Warren-Dearborn, MI Metropolitan Statistical Area; New York city, NY; the Cleveland-Elyria, OH Metropolitan Statistical Area; and the Seattle-Bellevue-Everett, WA Metropolitan Division, as well as the seven corresponding balance-of-state areas. As described above, the data incorporate new population controls, updated inputs, reestimation of models, and adjustment to new census division and national control totals. Both not-seasonally-adjusted and smoothed-seasonally-adjusted (SSA) monthly data for these areas were revised from January 2015 forward. The updated population controls reflect recent U.S. Census Bureau revisions from April 2010 forward.

Statewide data for Puerto Rico (which are not model-based, but rather are tabulated from a household survey similar to the Current Population Survey for the U.S.) similarly were revised from January 2015 forward. The not-seasonally-adjusted data reflect the incorporation of new population controls, while the SSA data reflect seasonal adjustment and smoothing of the recontrolled not-seasonally-adjusted data.

Annual-average and historical supplemental items on the website containing data for model-based areas, including data files, rank tables, and maps, were updated on or shortly after March 4 to reflect these revisions.

In conjunction with the revisions for model-based areas, statewide series for civilian noninstitutional population ages 16 and older, labor force participation rates, and employment-population ratios were loaded into the BLS time-series database on March 4. Previously, these measures had been available only in the supplemental series files listed toward the bottom of www.bls.gov/lau/rdscnp16.htm.

Substate Areas

In conjunction with the issuance of the Metropolitan Area Employment and Unemployment news release for January 2020 on March 20, data from 2010 forward were restored in the BLS time-series database for New England towns with 2010 Census populations of less than 1,000. These areas had been discontinued from publication in early 2018, with their series truncated at the end of 2009 at the time.

On April 17, 2020, routine revisions will be made to data from 2015 through 2019 for geographic areas below the state level (other than the model-based areas noted above), and official annual averages for 2019 will be issued. For substate areas, estimation inputs generally will be revised back to 2018, while the revisions for 201517 generally will consist of controlling to the new state totals described above. However, some states will have revisions as far back as January 2010.
