Every year, the U.S. Census Bureau issues a report on the overall state of public education finances in the U.S. There is usually a roughly 2-3 year lag on the data – for example, the latest report applies to the 2011-12 fiscal year – but the report and accompanying data are a good way to keep an eye on the general education finance situation both in individual states as well as nationwide, particularly among those of us who are somewhat casual followers (though it bears keeping in mind that these data do not include many charter schools).
One of the more interesting trends in recent years is the breakdown of total revenue by source. As most people know, U.S. public school systems are funded by a combination of federal, state and local revenue. Today, although states vary considerably in the configuration of these three sources, on the whole, most funding comes from state and local revenue, with a smaller but still significant contribution from federal government sources (total revenue in 2011-12 was about $595 billion).
But there has been some volatility in these relative contributions over the past few years (at least the past few years for which data are available). The graph below presents the percent of total elementary/secondary education revenue from federal, state and local sources between 1989-90 and 2011-12.
