Analysis of individual-level data from the 1970 Census confirms earlier findings, based on census tract data, about Hispanic and Black spatial assimilation in selected cities. Besides validating the theory of spatial assimilation, the results also indicate that errors resulting when individual-level inferences are made from ecological data are…

Analyzes the scale and size distribution of U.S. metropolitan areas from 1910-95. Before World War II, the population became increasingly concentrated in the largest metropolitan areas in the top decile of size distribution. Since 1950, there has been loss of population share for these areas. This is not counterbalanced by increasing share among…

Revision of a paper prepared for discussion at the Columbia University Seminar on Population and Social Change, December 1967.

This paper describes and tests a series of hypotheses about the effects of locality characteristics upon the growth of nonmetropolitan urban places. In the cross-sectional analysis of this study, the potential effectiveness of resource-based development seems limited as a factor in urban growth except in the North Central region. On the other…

Analyzes the racial breakdowns of population by census tract for Chicago; these figures, released in April 1970 by the Bureau of Census, use the Negro consolidation index which measures the rapidity of racial turnover of a neighborhood after entry by blacks. (JM)

Data from a land-use study of small- and medium-sized towns in New Zealand are used to ascertain the relationship between official and effective density measures. It was found that the reliability of official measures of density is very low overall, although reliability increases with community size. (Author/RLV)

A prediction from ecological theory relating the distribution of residential segregation between inner and outer zones of a metropolitan area to conditions of population growth, expansion, etc. was tested using 1960 data on the Atlanta standard metropolitan statistical area. (JM)

Explanations for growth beyond central city borders are examined. Presented is a general overview of the confrontation between conventional and critical urban theory. (Author/RM)

Investigated in this article are several factors that affect the annexation by central cities of urbanized areas to retain decentralized populations. A multivariate model of the responses of central cities to over- and underboundedness is presented and evaluated. (Author/EB)

This research study explores changes in the geographic dispersal of social classes in Philadelphia over a 20-year period. Discussed are the changes which occurred between the central city and its suburbs and those which occurred among suburban municipalities. Descriptions of several hypothetical models about the changes are tested. (EB)

Data for 318 metropolitan areas confirm the Burgess model's positive relationship between social status and residential distance from the urban core. Over time, all categories of metropolitan areas moved in the predicted direction of status distribution, with stronger associations for older, larger, and more industrial cities. Contains 53…

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)

Discusses the increasing proportion of minority enrollments in urban schools and the ensuing social isolation of Black and Hispanic American students. Reviews four models of metropolitan school desegregation plans. Suggests a federal initiative that would require states to develop plans involving multiple school districts. (FMW)

A detailed regional profile that compares rural and urban populations of seven North Central states (Illinois, Indiana, Iowa, Michigan, Minnesota, Ohio, and Wisconsin) is presented in this report. Following an overview of the report, sources, and definitions, the next eight sections discuss the region as a whole and each of the seven states by…

This United Nation's publication presents data on the size and growth of urban and rural populations for all countries of the world and contains revised estimates and projections for all urban agglomerations that had at least one million inhabitants in 1990. Chapter 1 presents levels of urbanization and future trends for urban and rural…
