From the summary:
The Census Bureau will release alternative income and poverty estimates covering calendar year 2008. The data were collected from the 2009 Current Population Survey (CPS) Annual Social and Economic Supplement (ASEC). The first set of alternative measures include poverty estimates only and are based on recommendations from a 1995 National Academy of Sciences panel on measuring poverty. These estimates use a broadened definition of income and a set of poverty thresholds that are conceptually consistent with this income measure. The second set of alternative measures includes both income and poverty estimates and shows the impact of cash and noncash benefits and taxes on the distribution of income and prevalence of poverty. The poverty estimates in this series are based on the official poverty thresholds. Both of these alternative measures are similar to estimates released in January 2009 covering calendar year 2007 from the 2008 CPS ASEC.
