This report is divided into seven sections. Section one deals with the design of the study which includes the basic questions asked, the nature of the data collected in order to answer these questions, and the samples upon which the statistical analyses are performed. Sections two and three are concerned with the matter of social and economic inequalities among suburban school districts and specifically with trends through time with respect to these inequalities. Sections four and five are devoted to an investigation of the determinants of local spending for education. Section six concentrates upon the role of state aid both with respect to the social and economic inequalities previously explored, and with respect to the determination of local expenditure levels. In the final section the empirical findings are summarized and some recommendations for legislative action are offered. (Author)
