TECHNICAL NOTES
This news release presents the weekly unemployment insurance (UI) claims reported by each state's unemployment
insurance program offices. These claims may be used for monitoring workload volume, assessing state program
operations and for assessing labor market conditions. States initially report claims directly taken by the state liable for the
benefit payments, regardless of where the claimant who filed the claim resided. These are the basis for the advance initial
claims and continued claims reported each week. These data come from ETA 538, Advance Weekly Initial and
Continued Claims Report. The following week initial claims and continued claims are revised based on a second
reporting by states that reflect the claimants by state of residence. These data come from the ETA 539, Weekly Claims
and Extended Benefits Trigger Data Report.
A. Initial Claims
An initial claim is a claim filed by an unemployed individual after a separation from an employer. The claimant requests
a determination of basic eligibility for the UI program. When an initial claim is filed with a state, certain programmatic
activities take place and these result in activity counts including the count of initial claims. The count of U.S. initial
claims for unemployment insurance is a leading economic indicator because it is an indication of emerging labor market
conditions in the country. However, these are weekly administrative data which are difficult to seasonally adjust, making
the series subject to some volatility.
B. Continued Weeks Claimed
A person who has already filed an initial claim and who has experienced a week of unemployment then files a continued
claim to claim benefits for that week of unemployment. On a weekly basis, continued claims are also referred to as
insured unemployment, as continued claims reflect a good approximation of the current number of insured unemployed
workers filing for UI benefits. The count of U.S. continued weeks claimed is also a good indicator of labor market
conditions. While continued claims are not a leading indicator (they roughly coincide with economic cycles at their peaks
and lag at cycle troughs), they provide confirming evidence of the direction of the U.S. economy.
C. Seasonal Adjustments and Annual Revisions
Over the course of a year, the weekly changes in the levels of initial claims and continued claims undergo regularly
occurring fluctuations. These fluctuations may result from seasonal changes in weather, major holidays, the opening and
closing of schools, or other similar events. Because these seasonal events follow a more or less regular pattern each year,
their influence on the level of a series can be tempered by adjusting for regular seasonal variation. These adjustments
make trend and cycle developments easier to spot. At the beginning of each calendar year, the Bureau of Labor Statistics
provides the Employment and Training Administration (ETA) with a set of seasonal factors to apply to the unadjusted
data during that year. Concurrent with the implementation and release of the new seasonal factors, ETA incorporates
revisions to the UI claims historical series caused by updates to the unadjusted data. For further questions on the seasonal
adjustment methodology, please see the official release page for the UI claims seasonal adjustment factors or contact
BLS directly through the Local Area Unemployment Statistics web contact form.
