Smoothed Seasonally Adjusted Metropolitan Area Estimates
On May 1, 2019, seasonally-adjusted data for non-modeled metropolitan areas and metropolitan divisions were updated from January 2010 forward based on revised historical
not-seasonally-adjusted estimates and re-fitting of seasonal-adjustment models. At the same time, the data were smoothed using the Reproducing Kernel Hilbert Space (RKHS)
filter that had been implemented for model-based areas in early 2018. The implementation of the smoothing filter resulted in changes back to the series beginnings in January 1990.
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 1990 forward. The statistical technique used to adjust estimates is SEATS, or
Signal Extraction in ARIMA (Auto Regressive Integrated Moving Average) Time Series. Following seasonal adjustment, the data are smoothed using a Reproducing Kernel
Hilbert Space (RKHS) filter. For each area and division, separate SEATS specifications are used to seasonally adjust employment and unemployment levels, from which
civilian labor force levels and unemployment rates are then derived. The SEATS specifications also vary by decade (1990-99 and 2000 forward), in order to minimize
performance problems stemming from decennial discontinuities in the not-seasonally-adjusted input data.
For the sake of completeness, data for model-based areas and divisions are included in the files below. These are the Cleveland-Elyria, OH, and Detroit-Warren-Dearborn, MI,
metropolitan areas and the Chicago-Naperville-Arlington Heights, IL; Los Angeles-Long Beach-Glendale, CA; Miami-Miami Beach-Kendall, FL; and Seattle-Bellevue-Everett, WA, metropolitan
divisions. Data for these model-based areas and divisions first are seasonally adjusted using an X-11 type of filter then are smoothed using an RKHS filter, as are the model-based
data for states.
