Effective with data for January 2023, updated population estimates were incorporated
into the household survey. Population estimates for the household survey are developed
by the U.S. Census Bureau. Each year, the Census Bureau updates the estimates to
reflect new information and assumptions about the growth of the population since the
previous decennial census. The change in population reflected in the new estimates
results from adjustments for net international migration, updated vital statistics, and
improvements in estimation methodology.
In accordance with usual practice, BLS will not revise the official household survey
estimates for December 2022 and earlier months. However, to show the impact of the
population adjustments, table B displays differences in selected December labor force
series based on the old and new population estimates.
The adjustments increased the estimated size of the civilian noninstitutional
population in December by 954,000, the civilian labor force by 871,000, employment by
810,000, and unemployment by 60,000. The number of persons not in the labor force
increased by 82,000. Although the total unemployment rate was unaffected, the
employment-population ratio and labor force participation rate each increased by 0.1
percentage point.
Data users are cautioned that these annual population adjustments can affect the
comparability of household data series over time. Table C shows the effect of the
introduction of new population estimates on the change in selected labor force
measures between December 2022 and January 2023. Additional information on the
population adjustments and their effect on national labor force estimates is
