Recent migration trends affecting the Tokyo metropolitan area (TMA) in Japan are analyzed. The focus is on the factors affecting the change in migration patterns which resulted in a net outflow of migrants from the area in 1994, the first time this has occurred. "The results from a set of time-series analyses lead the authors to conclude that, as far as the study period (1979-92) as a whole is concerned, the changing migration pattern of the TMA arose from factors closely related to Tokyo's transformation into a world city (specifically in terms of industrial restructuring and changes in residential land prices) and from cycles of economic boom and bust. However, it was found that the change to world city was more important than the economic cycle. Such findings suggest that the Japanese migration system experienced structural change during the 1980s and entered a new phase in the 1990s."

The author adopts "Coale's scenario-building approach to focus on some of the demoeconomic consequences of rapid urbanization....[He describes] the construction and evolution of four alternative population scenarios and then [examines] the implications that these alternative trends in migration and fertility would have for Coale's three important population characteristics: the dependency burden, the growth rate of labor force 'eligibles,' and the density of the population."

The author "has examined trends in interstate migration during the 1970s for the four regions of the United States and, in particular, explored the relationship of this migration with nonmetropolitan expansion and the return to the city movement. The data show that the former trend is a very real one which has persisted throughout the decade and that population growth through interstate migration in nonmetropolitan America is, on balance, the result of nonblacks moving to the South from elsewhere in the nation. Except in the West, central cities continue to experience substantial losses of population through interstate migration. Interstate migration continues to be directed toward suburbs, and is especially vigorous in the West." Data are from the March 1975 and March 1979 Current Population Surveys.

"A sample of Soviet cities (the largest 100 cities in the RSFSR) is used to develop a model relating city size, city function and the city's force of attraction (in-migration rates)....[It is found that] city growth...is accompanied by a change in functional structure and an increase in the importance of some functions at the expense of others....A change in functional structure, in turn, produces a change in the city's force of attraction, resulting in either an increase or a decline of in-migration."
"A number of investigators have noted a movement of Soviet population toward the seacoasts, contrasting with the nation's traditional inland development. The pull of the coast has been linked to the increasing foreign trade of the USSR and to greater involvement in ocean affairs in general. The author analyzes the recent growth of maritime urban places in terms of the nation's major maritime regions: Azov-Black Sea, Baltic, Caspian, Pacific and Arctic, compares the rates of urban population growth and discusses some of the factors that account for differences in regional development."
"A time-minimization problem of attaining a full-employment state is solved in a dual economy model where the rural-urban migration mechanism is of [the] Harris-Todaro type. The optimum solution may appear as a policy of urban development at the most rapid rate."
