There
have been substantial changes made to the 2008 American Community
Survey (ACS) questions on labor force participation and number of weeks
worked. After thoroughly investigating the extent to which each of the
Kids Count indicators of economic well-being may be affected, we believe
that the changes in methodology were significant enough to constitute a
break in the trend. We therefore do not recommend that you make
comparisons to previous years’ estimates.

2007 and 2008 state-level estimates of employment and unemployment read
