According to a report from The Pew Charitable Trusts released in February 2020, states derive roughly one-third of their revenue from the federal government, funding that pays for health care, schools, roads, public safety, and other services. Since 2008, those grants have increased by 42 percent from $448 billion to $636 billion, adjusted for inflation, driven by rising Medicaid costs.
