This study uses aggregate intertemporal poverty indices proposed by Gradin, Del Rio, and Canto (2012) to measure poverty among older American households of different races from 2001 through 2009 employing data from the Health and Retirement Study. The findings indicate that the incidence of intertemporal poverty is higher among Black and Hispanic households and that it is also more intense and of longer duration. In our investigation of antipoverty effects of the Supplemental Nutrition Assistance Program, we find that the program has a significant impact in reducing intensity and inequality of poverty among poor populations. However, it does not significantly alter the incidence of intertemporal poverty.
