Unreliable Sources: Education Revenue During The Recession
For the better part of the past century, U.S. public education revenue has come predominantly from state and local sources, with the federal government contributing only a relatively small share. For most of this time, local revenue (primarily property taxes) comprised the largest proportion, but this began to shift gradually during the 1970s, to the point where state funds constituted a slightly larger share of overall revenue.
As you can see in the simple graph below, which uses data from the U.S. Census Bureau, this situation persisted throughout the 1990s and most of the 2000s. During this period, states provided roughly 50 percent of total revenue, localities about 45 percent, and the federal government approximately 5-8 percent. Needless to say, these overall proportions varied quite a bit by state. Vermont represents one of the most extreme examples, where, as a result of a 1997 State Supreme Court decision, education funding comes almost entirely from the state. Conversely, since Hawaii’s education system consists of a single statewide district, revenue on paper is dominated by state sources (though, in Hawaii's case, you might view the state and local levels as the same).
That said, the period of 2008 to 2010 was a time of pretty sharp volatility in the overall proportions contributed by each level of government.
