Resources for the Future is a nonprofit corporation for research and education
in the development, conservation, and use of natural resources. It was established
in 1952 with the co-operation of The Ford Foundation and its activities since then
have been financed by grants from that Foundation. Part of the work of Resources
for the Future is carried out by its resident staff, part supported by grants to
universities and other nonprofit organizations. Unless otherwise stated, interpreta-
tions and conclusions in RFF publications are those of the authors; the organization
takes responsibility for the selection of significant subjects for study, the competence
of the researchers, and their freedom of inquiry.

This book is one of RFF's regional and urban studies, which are directed by
Harvey S. Perloff. Wilbur R. Thompson, professor of economics at Wayne State
University, began the present study in 1961 as an RFF research associate, while on
leave from his university. Through an RFF grant to Wayne State he began another
assignment with RFF in 1964 as staff director of the Committee on Urban Economics.

Director of RFF publications, Henry Jarrett; editor, Vera W. Dodds; associate
editor, Nora E. Roots.
