On Long Island in New York State, approximately 3/4 of all public
school expenses are paid by local taxpayers. The remaining 1/4
is paid by the state government. In the early 1990s, there were
large budget cuts by the state, resulting in a nearly 20\% decline
in state aid to the schools. Researchers wish to
examine the pattern of aid allocation across districts. 

The data are: percent change in state aid from the 1984-1985 school year
to the 1994-1995 school year, average ninth grade class size, and 
percent of students which are white, for each district in Nassau County.

These data come from:  Chatterjee, Handcock, and Simonoff (1995).

The authors originally obtained the data from a Newsday article on 
September 4 1994, which reported figures from the New York Department of
Education.
