The "Analysis of School Finances in New York State School Districts" is an annual publication providing a meaningful perspective to staff in the Division of the Budget, the Legislature, the Education Department, and school officials concerning school expenditures, State Aid, and local support. This edition of the Analysis summarizes the finances of the 674 major school districts in school year 2016-17, as well as public school expenditures and State Aid since 1998-99. In summarizing school district expenditures, the Analysis compares various percentiles of operating expenditures per pupil and describes the magnitude of the disparity in approved operating expenditures per pupil between districts in the 10th and 90th percentiles for each year. Decile tables ranked by wealth, expenditure per pupil, and need/resource index are also included. These decile tables provide comparisons of school districts' expenditures per pupil, tax rates, and wealth per pupil. Another feature of the Analysis is its presentation of five-year trend data on full value, expenditures, State Aid, tax rates, and local revenue. These items are displayed on a per pupil basis for the entire State, New York City, and the rest of State (school districts outside New York City).
