FRED has reestablished an update of Moody’s Aaa and Baa corporate bond yields. These series are constructed by Moody’s from bonds with maturities of 20 years and above.

These 3,143 county-level series measure the percentage of a racial group’s population in a county who would have to move Census tracts for each tract in that county to have the same percentage of that group as the whole county. Jahn, Schmid and Schra originally developed this process of measuring racial equalization in 1947. The U.S. Census Bureau’s American Community Survey provides the composite county- and tract-level data.

These 3,139 county-level series come from the Dartmouth Atlas of Healthcare. The Dartmouth Atlas of Healthcare calculates the preventable hospital admissions rate by dividing the number of discharges of ambulatory care sensitive conditions per 1,000 medicare enrollees.

These 3,143 county-level series come from the U.S. Census Bureau’s American Community Survey. Each series represents the percentage of the population in a county who live below the federal poverty line.

These 3,143 series on commute time are calculated from the U.S. Census Bureau’s American Community Survey. Each series is calculated by dividing the aggregate travel time to work for all workers by the total number of workers, 16-years of age and older, who commute.

These 3,140 series are calculated from the U.S. Census Bureau’s American Community Survey. For each series, the 20:20 ratio is used to determine the level of inequality in a county. The 20:20 ratio is the ratio of the mean income for the highest quintile (top 20 percent) of earners divided by the mean income of the lowest quintile (bottom 20 percent) of earners for a particular geographical area.
