HISTORICAL SPM DATA

With funding from the Annie E. Casey Foundation and The JPB Foundation, CPSP researchers have created a historical version of the Census' and Bureau of Labor Statistics' Supplemental Poverty Measure (SPM), which dates back to 1967. The SPM improves upon official poverty statistics by taking a fuller accounting of the resources that families have at their disposal. As such, it is a useful tool for analyzing the effects of social policies on the lives of low-income families.

hISTORICAL SPM DATA TABLE

The CPSP has released a data table featuring the poverty rates from 1967 to 2017 measured under the Supplemental Poverty Measure (SPM). The data table includes the historical SPM poverty rates and the SPM poverty rates anchored to the 2012 SPM poverty thresholds, both with and without taxes and transfers. Results are calculated at the population level, as well as for children, working-age adults, and the elderly. This data table allows researchers to determine poverty rates in a given year without needing to download the historical SPM public-use data files.
