This data is described by PEW as follows:  "Data for the federal share of state revenue are drawn from the U.S. Census Bureau’s Annual Survey of State Government Finances and Annual Survey of State & Local Government Finances. These surveys provide yearly data on states’ revenue, including tax revenue, higher education tuition, hospital fees, and revenue from federal and local government sources. For each state, this indicator divides the total amount of federal revenue to the state, most of which is in the form of grants, by the total amount of state revenue for the year to calculate the federal share of that state’s revenue. The denominator is the Census Bureau’s “general revenue,” which is broader than what most state budget officials call “general fund” revenue. General revenue accounts for all state revenue sources except state-owned liquor stores, utilities, and insurance trust funds. The 50-state share is the total amount of federal grants to states divided by the total amount of state revenue, excluding the revenue sources previously noted."

Source: Pew’s analysis is based on states’ sources of revenue data from the U.S. Census Bureau’s “Annual Survey of State Government Finances”  for all years except fiscal 2012 for New York. Data for New York in fiscal 2012 are from the Census Bureau’s “Annual Survey of State & Local Government Finances”. Data for the dates and number of states that adopted the Medicaid expansion under the Affordable Care Act are drawn from the Henry J. Kaiser Family Foundation’s “Status of State Action on the Medicaid Expansion Decision,” accessed May 15, 2019.
