Abstract:	In 2004 the U.S. Bureau of Labor Statistics plans to adopt concurrent seasonal adjustment for national household employment and unemployment data from the Current Population Survey. Gains from concurrent over the present method with projected factors will be presented for 21 series, including the national unemployment rate and series used to derive it. Revision diagnostics for both levels and month-to-month changes are analyzed. Alternative revisions policies with concurrent will be examined, including no revision, revising last month only, and revising all values.
