The unique health and aging challenges of rural populations often go unnoticed. In fact, the United States is home to disproportionate shares older sicker people, there are large growing rural-urban within-rural mortality disparities, many communities in population decline, racial/ethnic diversity increasing.Yet not monolithic, although some places characterized by declining health, others have seen improvements health. We draw on these realities call for new research five areas.First,...

Underemployment goes beyond mere unemployment (being out of a job looking for work), include those who have given up work, part‐time workers whose employer(s) cannot give them full‐time the working poor.

A broad literature has made it clear that geographic units must be selected with care or they are likely to introduce error and uncertainty into results. Nevertheless, researchers often use data “off the shelf” implicit assumptions their observations consistent geographical concept relevant for research question, of uniformly high quality in capturing this identity. In paper, we consider “labor market” offer a template both clarifying its meaning testing suitability extant labor-market...

A bstract The “rural paradox” refers to standardized mortality rates in rural areas that are unexpectedly low view of well‐known economic and infrastructural disadvantages there. We explore this paradox by incorporating social capital, a promising explanatory factor has seldom been incorporated into residential research. do so while being attentive spatial dependence, statistical problem often ignored Analyzing data for counties the contiguous United States, we find that: (1) is confirmed...

Abstract Underemployment, which goes beyond unemployment to include the working poor, discouraged workers, and involuntary part‐time is a useful measure of employment hardship. We argue that underemployment should be included with other conventional indicators disadvantaged circumstances nonmetropolitan (nonmetro) labor, in terms not only prevalence, but also likelihood transitions into out underemployment. take advantage quasi‐longitudinal nature U.S. Current Population Surveys estimate...

Elderly persons in nonmetropolitan areas are more likely to be poor than their metropolitan counterparts, and the gap between them increases with age. This study provides a comprehensive empirical comparison of nature income poverty among (metro) (nonmetro) elders. Drawing on 1990 Current Population Survey, we document differences by age for various demographic subgroups elderly population. These analyses show that rates higher nonmetro elders virtually all subgroups. We estimate logistic...
