Ties That No Longer Bind? The Patterns and Repercussions of Age-Articulated Migration

Abstract: Rates of geographical mobility vary greatly, and fairly predictably, across the life course. Our analysis of special county-to-county migration tabulations of Census 2000 data discloses that, when flows are disaggregated by age, radically different patterns of net population redistribution are taking place upward and downward within the national urban hierarchy. The movements at the late-career, empty-nester, and retirement stage are the most “demographically effective” or unidirectional. The elderly fleeing large metropolitan areas have been congregating in micropolitan and rural counties with special climatic and other natural amenities. The opposite net flow is found for younger adults, who have been flocking into megametropolitan conurbations. At the midcareer stage, the net movement is from larger to medium metropolitan areas. We detail the age articulation of county-to-county migration flows with novel graphical portrayals and statistical measures. We give some thoughts on the relationship between i...

Spatial patterns of hospital utilization: the impact of distance and time.

Abstract: Although the impact of the physical proximity of health care facilities on utilization in rural areas is well established, its effect in metropolitan areas is still subject to question. This paper develops a spatial demand model of hospital choice to empirically estimate the impacts of distance and time on hospital utilization patterns. With a cross-product ratio estimation approach, the effects of physical access are estimated after controlling for spatial irregularities owing to the distribution of hospitals and population in metropolitan areas. The empirical results suggest that distance and time factors strongly influence hospital choice, even in metropolitan areas where alternatives are widely available, and that their effects vary across service classifications and hospitals.

An agent-based model for domestic water management in Valladolid metropolitan area.

Abstract: [1] In this work we demonstrate that the combination of agent-based modeling and simulation constitutes a useful methodological approach to dealing with the complexity derived from multiple factors with influence in the domestic water management in emergent metropolitan areas In particular, we adapt and integrate different social submodels, models of urban dynamics, water consumption, and technological and opinion diffusion, in an agent-based model that is, in turn, linked with a geographic information system The result is a computational environment that enables simulating and comparing various water demand scenarios We have parameterized our general model for the metropolitan area of Valladolid (Spain)The model shows the influence of urban dynamics (eg, intrapopulation movements, residence typology, and changes in the territorial model) and other socio-geographic effects (technological and opinion dynamics) in domestic water demand The conclusions drawn in this way would have been difficult to obtain using other approaches, such as conventional forecasting methods, given the need to integrate different socioeconomic and geographic aspects in one single model We illustrate that the described methodology can complement conventional approaches, providing descriptive and formal additional insights into domestic water demand management problems
