DEPARTMENT OF LABOR
Bureau of Labor Statistics
Proposal to Revise Method for Estimation of Monthly Labor Force
Statistics for Certain Subnational Areas
AGENCY: Bureau of Labor Statistics, Labor.
ACTION: Request for comments on proposed action.
-----------------------------------------------------------------------
SUMMARY: The Department of Labor, through the Bureau of Labor
Statistics, is responsible for the development and publication of local
area labor force statistics. This program includes the issuance of
monthly estimates of the labor force, employment, unemployment, and the
unemployment rate for each State and labor market area in the nation.
For 11 large States (California, Florida, Illinois, Massachusetts,
Michigan, New Jersey, New York, North Carolina, Ohio, Pennsylvania,
Texas) and two large areas (New York City, and the Los Angeles
Metropolitan Area), the Current Population Survey (CPS) sample is
sufficiently large to meet the BLS standard for direct use and the
monthly estimates are taken directly from the survey. Historically,
concern has been expressed over the volatility of monthly CPS estimates
in these large States and areas.
Under anticipated lower funding levels, BLS plans to reduce the
number of households in the CPS. One result will be that the 11 large
States and two large areas no longer will be estimated directly from
the monthly household survey. The BLS proposes to continue publishing
monthly estimates for these subnational areas based on the time series
modeling approach currently used in the other 39 States and the
District of Columbia beginning in January 1996.
DATES: Comments are due by December 1, 1995.

Area Unemployment Statistics, Bureau of Labor Statistics, Suite 4675, 2

SUPPLEMENTARY INFORMATION: The Bureau of Labor Statistics (BLS) has
been responsible for the Local Area Unemployment Statistics (LAUS)
program since 1972. In 1978, the BLS broadened the use of data from the
Current Population Survey (CPS) in the LAUS program by extending the
annual reliability criterion to monthly data. This action was within
the context of a budget proposal to expand the CPS to yield monthly
employment and unemployment data for all States by June 1981. Under the
expanded criterion, monthly CPS levels were used directly for the 10
largest States, two sub-State areas, and the respective balance-of-
State areas. The use of annual average CPS data continued for the other
40 States and the District of Columbia. Ultimately, the budget proposal
which initiated the direct use of monthly State CPS data was rejected
as too costly. Based on population ranking, the State of North Carolina
joined the group of direct-use States in 1985, bringing that group to
its current total size of 11 States. Also in 1985, sample redesign and
other efficiencies improved the reliability of CPS data at the State
level, resulting in the current criterion on monthly and annual average
data of an 8 percent coefficient of variation on the level of
unemployment when the unemployment rate is 6 percent.
Especially in regard to the monthly direct use of State CPS data,
concern has been expressed as to the volatility of the statistics. In
the typical direct-use State, a month-to-month change in the
unemployment rate must exceed 0.7 percentage point to be considered
statistically significant. Often, States experience consecutive,
offsetting large movements in the unemployment rate.
For the other 39 States and the District of Columbia, after
extensive research and simulation, variable coefficient time series
models for monthly estimation of State employment and unemployment were
introduced in 1989. Further improvement was effected with the
implementation of signal-plus-noise models in 1994. These models rely
heavily on monthly CPS data, as well as current wage and salary
employment and unemployment insurance statistics. At the end of each
year, the monthly model estimates are rebenchmarked so that the annual
averages for each State match the annual averages derived directly from
the CPS.
Because of the budget reductions that the Bureau anticipates, the
CPS sample may not be of sufficient size to provide monthly data
directly for the 11 large States, New York City, and the Los Angeles
Metropolitan Area. Monthly estimates will continue to be produced,
based on the time series modeling method currently used for the other
States and the District of Columbia. Data for the current direct-use
States and
[[Page 55856]]
areas would no longer be released by the BLS at the same time as the
monthly national labor force statistics, but would be published about
four weeks later in the State and Metropolitan Area Employment and
Unemployment news release. States that are able to do so will have the
option of releasing these data earlier, perhaps even simultaneously
with the release of national data. Monthly data for these States also
will become subject to end-of-year benchmarking.
The impact of the CPS sample cut on the national statistics would
be to increase the variability of most national estimates by about 5
percent. For example, under the reduced sample, a month-to-month change
of 0.19 percentage points in the national unemployment rate would
represent a statistically significant change at the 90-percent
confidence level; the corresponding change under the current design is
0.18 percent.
Detailed descriptions of the estimating methods are available at
the above address.
