Six alternative measures of labor underutilization have long been available on a monthly basis from the Current Population Survey (CPS) for the United States as a whole. They are published in the Bureau of Labor Statistics' monthly Employment Situation news release. (See table 15.) The official concept of unemployment (as measured in the CPS by U-3 in the U-1 to U-6 range of alternatives) includes all jobless persons who are available to take a job and have actively sought work in the past four weeks. This concept has been thoroughly reviewed and validated since the inception of the CPS in 1940. The other measures are provided to data users and analysts who want more narrowly (U-1 and U-2) or broadly (U-4 through U-6) defined measures.

BLS is committed to updating the alternative measures data for states on a 4-quarter moving-average basis. The use of 4-quarter averages increases the reliability of the CPS estimates, which are based on relatively small sample sizes at the state level, and eliminates seasonality. Due to the inclusion of lagged quarters, the state alternative measures may not fully reflect the current status of the labor market. The latest estimates are the 2013 annual averages. Data are also available for the following periods:

- Fourth quarter of 2012 through third quarter of 2013
- Third quarter of 2012 through second quarter of 2013
- Second quarter of 2012 through first quarter of 2013
- 2012 annual averages
- Fourth quarter of 2011 through third quarter of 2012
- Third quarter of 2011 through second quarter of 2012
- Second quarter of 2011 through first quarter of 2012
- 2011 annual averages
- Fourth quarter of 2010 through third quarter of 2011
- Third quarter of 2010 through second quarter of 2011
- Second quarter of 2010 through first quarter of 2011
- 2010 annual averages
- Fourth quarter of 2009 through third quarter of 2010
- Third quarter of 2009 through second quarter of 2010
- Second quarter of 2009 through first quarter of 2010
- 2009 annual averages
- Fourth quarter of 2008 through third quarter of 2009
- Third quarter of 2008 through second quarter of 2009
- Second quarter of 2008 through first quarter of 2009
- 2008 annual averages
- 2007 annual averages
- 2006 annual averages
- 2005 annual averages
- 2004 annual averages
- 2003 annual averages

The six state measures are based on the same definitions as those published for the U.S.:

- U-1, persons unemployed 15 weeks or longer, as a percent of the civilian labor force;
- U-2, job losers and persons who completed temporary jobs, as a percent of the civilian labor force;
- U-3, total unemployed, as a percent of the civilian labor force (this is the definition used for the official unemployment rate);
- U-4, total unemployed plus discouraged workers, as a percent of the civilian labor force plus discouraged workers;
- U-5, total unemployed, plus discouraged workers, plus all other marginally attached workers, as a percent of the civilian labor force plus all marginally attached workers; and
- U-6, total unemployed, plus all marginally attached workers, plus total employed part time for economic reasons, as a percent of the civilian labor force plus all marginally attached workers.
