Migration data suggest an evolutionary process in which central cities attract high status migrants when cities are relatively small, attract migrants less as they grow, and then again become attractive. Large northern cities may currently be in the middle stage. (Author/MJL)

The cumulative adverse impact of residential white flight from large central cities on the residual population has led policy makers to be wary of instituting programs which will further exacerbate the process. Recent policy debates have evolved over the question of whether white city-to-suburb movement is affected more significantly by…

The 1980 United States Census showed a marked acceleration in the suburbanization of blacks during the 1970s. This study analyzes statistical data from the 1985 American Housing Survey (AHS) National and Metropolitan Files to determine if that pattern of acceleration continued in the 1980s. These sets of data also permitted racial and…

The United States is a highly urbanized nation with space in abundance, yet large portions of its national territory are emptying out. The counterpart of this pervasive population decline is a highly selective pattern of growth, conferred by a national system of migration flows that has increasingly favored a certain few metropolitan areas. This…

This report contains the text of five briefings on research in Rand's Urban Policy Analysis program. "Brief History of Rand's Urban Policy Analysis Program," by Barbara R. Williams, discusses the changing Federal role in urban policy, problems encountered in Rand's attempt during the early 1970s to examine the central policy problems of…

It is proposed in this document that the selectivity of migration, in terms of both people and places become a more imposing influence in urbanization as the role of natural increase as a source of urban growth diminishes. Recent U.S. growth policy proposals have frequently been marked by a simplistic view of how urban growth works, compounded by…

Adopting the demographer's cohort-component projection model, this study examines migration patterns for six cities. The results show that White and Black lifecourse migration patterns have become more alike in the post-1970 period; yet, significant racial disparities still exist. Thus, recent migration patterns do not imply eventual metropolitan…

Examines three hypotheses regarding the relationship between nativity, language affiliation, and interurban mobility in Canada during the intercensal period 1976-81. A series of crosstabular and logistic regression analyses provide support for all three hypotheses. Theoretical and policy implications are discussed in the context of ethnic…

Measures black segregation at four geographic levels: state, county, city, and neighborhood, from 1900 to 1990. Cross-references data from the decennial U.S. census with dissimilarity and isolation indices. Concludes that segregation patterns have consistently evolved to minimize white contact with blacks.

This paper focuses on partial models for solving urban problems to contrast our achievements as social scientists with our aspirations as prescribers of public policy. The objectives of this paper are (1) to review some of the reasons that an ideal set of solutions for urban problems has not been produced by social scientists and (2) to describe…

This report separates Puerto Ricans into four major subgroups: those who were born on the mainland and live either in New York City, or elsewhere in the United States, and those who were born in Puerto Rico and live either in New York City, or elsewhere in the United States. The report places considerable emphasis on those born on the mainland. A…
