A comprehensive survey of government activities in New York City's housing markets. The study covers 24 housing programs funded and administered by city, state, and federal governments, including land assembly and clearance, public ownership and operation of housing units, various forms of aid to private owners and developers, direct financial assistance to consumers of housing, regulation of rents, and enforcement of construction and maintenance standards. Sources of information were reports published by HDA and its predecessor agencies, the New York City Housing Authority, the City Planning Commission, and the Bureau of the Budget; unpublished data from the files of these agencies; expenditure records from the Office of the City Comptroller and from HDA's Bureau of Audit and Finance; reports and records of the New York State Division of Housing and Community Renewal and of the Federal Housing Administration. Annual outputs and expenditures for each program are compiled for the period 1963-1967. These data are used to compile a base case of outputs and expenditures for fiscal 1967-1968 as a benchmark for program budgeting for future years. 132 pp.
