Seasonally adjusted data for metropolitan areas and metropolitan divisions based on the 2010 Office of Management and Budget (OMB) delineations were
introduced on July 1, 2015. These replaced the smoothed seasonally adjusted data based on the 2000 OMB delineations that had been removed on March 17, 2015,
when the unadjusted input data were converted from the 2000- to the 2010-based OMB delineations.
The statistical technique being used to adjust estimates for the 2010-based areas and divisions is SEATS, or Signal Extraction in ARIMA (Auto Regressive
Integrated Moving Average) Time Series. For the 2000-based areas and divisions, a mixture of the SEATS and X-11 procedures had been used. Also, data for the
2010-based areas and divisions do not reflect the application of the Henderson 13 smoothing algorithm. This was determined to be unnecessary, because the
unadjusted input series are benchmarked prior to seasonal adjustment.
For the sake of completeness, data for model-based areas and divisions are included in the files below. These are the Cleveland-Elyria and
Detroit-Warren-Dearborn metropolitan areas and the Chicago-Naperville-Arlington Heights, Los Angeles-Long Beach-Glendale, Miami-Miami Beach-Kendall, and
Seattle-Bellevue-Everett metropolitan divisions. Data for these model-based areas and divisions are smoothed via a Trend-Cycle Cascade Filter, as are the
model-based data for states.
Effective with the release of metropolitan area data for May 2011, the Local Area Unemployment Statistics (LAUS) program began
to publish seasonally adjusted civilian labor force and unemployment estimates for all metropolitan areas and metropolitan
divisions. These data are updated via the downloadable files below on the day of each
Metropolitan Area Employment and Unemployment news release.
(See www.bls.gov/schedule/news_release/metro.htm for a schedule of upcoming release dates.) The files contain
estimates from January 2000 forward.
