Figure S2 in the report covers public community college revenue sources for 2000 to 2010.

As you can see most of the money is from the state/local level and a pretty high percentage is from net tuition. Of course this is going to vary a lot across the nation. Some schools have relatively low tuition rates and end up with a higher percent of the money coming from the state or local level. The chunk of revenue from the axillary category will probably vary tons as well.
