A study analyzed the revenues of the Chicago Public Schools since 1970; all the relevant data on these revenues are compiled in this document, which presents a comprehensive picture of the finances of the Chicago Public Schools. In response to a fiscal crisis that has continued since 1979-80, the Chicago Board of Education has cut its staff by nearly 18 percent, but the state legislature also cut the board's revenues by $40 million at the same time. For the last three years, the board has achieved a balanced budget by a series of one-time "gimmicks" to fill the gap between anticipated revenues and planned expenditures. The projected deficit for 1984-85 is now $171 million, primarily because revenue is expected to be $125 million lower for the following year. Accordingly, it seemed appropriate to examine revenues of the board from all sources, local, state, and federal, in this document. Major findings are as follows: (1) since 1978, total revenues have risen slowly; (2) the board's total purchasing power fell by 16.5 percent due to inflation; (3) local revenues have been static since 1972; (4) state aid has declined steadily since 1978 in constant dollars; (5) federal aid has kept pace with inflation, but educational programs have been drastically curtailed; (6) per student support, adjusted for inflation, has declined 19 percent since 1978; (7) Chicago stands sixth among eight major cities in per student revenues, but its balance of state/local revenues is comparable to that of other cities; (8) suburban Chicago districts have higher local tax rates and higher per student revenues and their share of state aid has increased since 1980; and (9) the school property tax burden has lagged behind inflation. The report concludes with recommendations to reverse the deterioration of public school funding and to restore federal support for educational programs to 1980 levels. Thirty-five tables are appended. (TE)
