The role of access in explaining state abortion rates.

The likelihood of having an abortion in the U.S.A. is strongly dependent upon where a woman lives. Abortion rates vary markedly from state to state, and these variations have been increasing, especially in recent years. Path analysis shows the causal structure of public demand and access variables that determined state abortion rates in 1991 and 1992. Access variables, including the restrictiveness of state laws regulating abortion, state funding of abortions for poor women and the availability of hospital abortions, affect abortion rates directly. Greater accessibility leads to higher abortion rates. Public demand variables affect abortion rates both directly and indirectly through access conditions. The number of women at risk of unintended pregnancies leads to higher abortion rates directly and indirectly through its effects on medical access. Per capita income, percent Catholic, and percent of the population born outside the state affect abortion rates indirectly through the access variables. High per capita income leads directly to greater availability of hospital abortions, higher levels of state funding of abortions for poor women, less restrictive state abortion laws, and indirectly to higher abortion rates. States with large non-native populations have less restrictive abortion laws and higher abortion rates. The presence of a large Catholic population reduces the number of hospitals offering abortion services and leads indirectly to lower abortion rates. The interaction of public demand and access at the state level creates geographically varying environments in which abortion decisions are made.

Using moving-industry data to depict U.S. migration patterns.

"Migration analysis is hindered by the lack of up-to-date migration data. This paper examines the feasibility of using information from the American Moving Conference (AMC), the trade organization of the moving industry, to develop timely estimates of gross in- and out-migration and net migration rates at the state level. When adjusted for the spatially varying size of migrant households and the spatially varying market share of the professional moving industry, the number of AMC inbound and outbound shipments provides useful, but slightly imperfect, estimates of migration in 1990 and 1991. Viewed as a time series, adjusted AMC shipment data accurately reveal the major migration stories of the last decade. AMC-based estimates for 1992, 1993, and 1994 provide a picture of state in- and out-migration for years in which official data are not yet available."

Short-term dynamics of the U.S. interstate migration system, 1980-1988.

"This paper identifies short-term fluctuations in the [U.S.] interstate migration system using annual state-to-state migration flow data from Internal Revenue Service (IRS) records for the period, 1980 to 1988. Measures of migration efficiency are employed to indicate the net redistribution of population between states relative to the size of underlying gross interstate flows. Three findings stand out: (1) migration was more effective in redistributing the population in years of economic retrenchment than during periods of growth and expansion, (2) the dominant pattern of population redistribution shifted from a core-periphery configuration evident in the 1970s and early 1980s to a bi-coastal distribution by the mid-1980s, and (3) the most dramatic event of the 1980s was the oil glut and decline in oil prices and profits which ravaged the economies of energy states in the West South Central and Mountain regions....Overall, results demonstrate the high degree of temporal and spatial volatility in the U.S. interstate migration system."

Urban housing demography.

"The purpose of this article is to review the literature in housing demography with emphasis on its geographic aspects." The differences among developed countries concerning patterns of home ownership are noted. "After a short discussion of households as the point of articulation between population and housing, I will examine interurban differentials in housing demography, review various population-oriented and housing-oriented approaches to intraurban housing demography, and finally, discuss the problems of and challenges for geographic research in this field."

Determinants of short- and long-term mobility expectations for home owners and renters.

Confusion about the role of residential satisfaction vis-à-vis structural factors in the mobility process stems from the failure to examine the determinants of mobility over varying time frames and housing tenures. Using survey data for a random sample of 580 Phoenix-area households, we test models of short-term (1 year) and long-term (5 years) mobility expectations for home owners and renters. The results show that residential satisfaction mediates the effects of structural variables on mobility expectations in the short term for home owners. In the long-term model for home owners and the short-term model for renters, the role of satisfaction as an intervening force declines in relative importance. Among renters, structural variables operate directly on long-term mobility expectations.

Homogeneity versus heterogeneity in household structure: the recent experience of twenty US cities.

"This paper is an investigation of the variation in household structure at the census tract level in twenty US cities between 1970 and 1980. Results indicate that households were, in 1980, more likely to reside in proximity to households with different compositions. In 1980 the most genuinely diverse census tracts, in terms of household composition, were in neighborhoods with recently constructed, single-family housing."

Falling household size and its effect on metropolitan population growth and density.

"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."
