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.
