The United States Small-Area Life Expectancy Project (USALEEP) is the first public health outcome measure available nationwide at the census tract level—measuring life expectancy at birth for nearly every neighborhood in the country. A joint effort of The Robert Wood Johnson Foundation, National Association for Public Health Statistics and Information Systems (NAPHSIS), and the National Center for Health Statistics (NCHS) at the Centers for Disease Control (CDC), USALEEP data provide unparalleled insights into community health and demonstrate that not everyone has the same opportunity to be healthy where they live.
