"The most urbanized provinces of the Netherlands are North-Holland, South-Holland and Utrecht. In these provinces, the population density (number of inhabitants per square kilometer of land) is five times that of the Northern provinces and Zeeland.... According to the Regional Population Forecasts 1994, up to 2015 all the provinces are expected to have a positive population growth. The population of the youngest province Flevoland will grow most rapidly: by about 50%. The population growth, both in relative and absolute terms, will be small in the Northern provinces and Zeeland (in the South West)." (SUMMARY IN ENG)
The author analyzes "levels and trends of urbanization in Bangladesh. It also makes an attempt to elucidate the implications of urbanization.... The...analysis corroborates that although the overall level of urbanization remained low, the sheer magnitude of total urban population has become formidable."

"The paper deals with the increasingly more unfavourable natural movement of the population in Croatia.... It is concluded that today's demographic dynamism and the structure of Croatia is a continuation of a long-term unfavourable process. The introduction of an appropriate population policy is necessary and should not be delayed, together with re-direction of...urbanization."

"In this paper we trace and interpret changes in the geographical pattern and city-size distribution of the world's largest cities in the twentieth century. Since 1900 the geographical distribution of these cities has become increasingly dispersed; their city-size distribution by rank was nearly linear in 1900 and 1940, and convex in 1980. We interpret the convex distribution which emerged following World War 2 as reflecting an economically integrated but politically and demographically partitioned global urban system. Our interpretation of changes in size distribution of cities emphasizes demographic considerations, largely neglected in previous investigations, including migration and relative rates of population change."

A model of urban population density functions is proposed that uses all available data on densities in urban areas. "This model postulates that population density at each census tract in each city is determined by city size, transportation costs, land supply, income and age of city." The model is applied to data on cities in Israel.
"The paper presents a discussion of the economic justification for taking cities seriously, a section outlining the scale of urbanisation and some of the issues raised, a section that discusses the policy approaches, one that looks at the local agencies for the formulation and execution of policy, and a short final part on some of the implications for aid policy." The focus is on the importance of the urban sector for economic development in developing countries.
"This study offers a broad overview of the urbanization dilemma in the Third World--within the context of elusive development--with particular attention to its current trends, components, consequences and policies to manage it."

"In the present study the allometric equations for urban places in the [United States] are derived and interpreted. Data on the area and population size of the urbanized area (as defined in the U.S. Census) for 1960, 1970, and 1980 are fitted to the allometric equation. The data set for each of the three time periods is further disaggregated by population-size class (seven classes) and by region (nine regions in total). The results of the analysis are interpreted with reference to works of allometric growth in the biology and urban growth literature."
"This paper investigates the relationship between economic development and primacy advanced by El-Shakhs, Mera and others, and finds no statistically significant link when obvious demographic influences are taken into account. Three variables (national population, the urban population share, and a Latin American dummy) explain 40% of the variation in primacy in a sample of 116 countries (including 82 developing countries). Economic factors do not appear to be important. Demography may be more influential than economics in attempts to explain primacy."
The relationship between economic development and urbanization in developing countries is reviewed. The authors conclude that urbanization is a necessary but not in itself a sufficient condition of development. They note that policies designed to either encourage or discourage urbanization have proved ineffective. Problems encountered are primarily due to the fact that, although urbanization is not occurring in developing countries at the same rate as it did previously in today's developed ones, the overall rate of population growth is much higher. "The degree of concentration of urban systems reflects a moving equilibrium between economies of agglomeration (centripetal), and diseconomies (centrifugal) and distance costs. Big city environmental costs are externalities not reflected in market prices, and which public authorities are called upon to manage. The choice of public investment in infrastructures can influence, marginally, the patterns of urban systems." (SUMMARY IN ENG)

"This paper analyses whether the basic monocentric model of urban structure and commuting explains actual commuting in Europe, i.e. The Netherlands. As in the USA much wasteful commuting is established. The basic model has a low degree of explanatory power. In order to get more in line with actual commuting, the paper elaborates two alternatives to the basic model. Besides a deconcentrated model, a cross-traffic model is developed. Particularly the latter is quite successful in explaining actual commuting. The paper pleads for endogenising employment and stresses heterogeneity in labour demand and supply."
