In this retrospective review of demographic aspects of race and the metropolis, presented as a basis from which to speculate about the 1970's, the period of mass migration of blacks out of the rural South is seen as drawing to a close. The U.S. black population is more urban and more metropolitan than the white population. The development of black…

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.

Despite gains in the number of blacks who found housing in the suburbs in the…

Aside from the growth of world population itself, urbanization is the dominant demographic trend of the late twentieth century. The number of people living in cities increased from six hundred million in 1950 to over two billion in 1986. If this growth continues unabated, more than half of humanity will reside in urban areas shortly after the turn…

The viability of urban cable television (CATV) as an economic phenomenon is examined via a case study of its feasibility in Boston, a microcosm of general urban environment. To clarify cable's economics, a unitary concept of viability is used in which all local characteristics, cost assumptions, and growth estimates are structured dynamically as a…
