Abstract
"In determining metropolitan population size and changes therein, urban theorists traditionally have focused on the number of occupied dwelling units or households and have assumed that these households are equal in size. This paper argues that average household size is an indicator of how intensively the housing stock is utilized and that there is substantial variation in household size across SMSAs in the U.S. The experience of 150 SMSAs is examined for the time period 1960 to 1970. The study model attributes varying household size to differentials in birth and divorce rates, racial composition and age of housing. Ramifications of recent household size declines involve the internal spatial organization of metropolitan areas and the Census controversy with cities over alleged undercounts of urban populations.", (excerpt)

Abstract
"This paper examines the impact of age on migration by providing estimates of identically specified migration equations for each of six age groups. Hypothesized effects of age on the relative importance of various explanatory variables are developed from a model viewing migration as an investment decision." This model is then tested empirically using U.S. data on inter-regional migration between 1965 and 1970. "The effects of economic opportunity differentials on migration are found to decline sharply with age. Lagged migration, the 'friends and relatives effect,' is found to be the most significant explanatory variable in all age group equations. Past migration is the only variable found to significantly influence the migration of persons over 65.", (excerpt)

Abstract
"This paper has examined the impact of climate on migration. It has compared the results that are obtained when various indicators of climatic conditions, both those which have been used in the literature and those which have not, are included in a regression used to explain migration behavior. The results suggest that individuals do indeed consider climatic conditions in different areas when deciding where to live; people generally prefer areas which have moderate climates to areas which have either extremely hot or extremely cold climates. The results also indicate that the climate variables which yield the best results are generally those which have not been used in the literature." The study is based on U.S. data concerning in-migration to 36 SMSAs between 1960 and 1970., (excerpt)

Abstract
"This paper presents and tests a regression-based model of black interstate migration. Explanatory variables include characteristics of origins and destinations, distance, and two migrant stock measures. The model is tested using black interstate migration flows published by the U.S. Bureau of the Census for 1965-70 and 1975-80." The emphasis is on the determinants of black migration, particularly for the period 1975-1980., (excerpt)
