Absolute income mobility obscures marginalized children's disadvantages.

Intergenerational mobility captures the distance between the socioeconomic positions of parents versus their adult children. Researchers measure this distance in absolute and relative units, such as absolute dollars and relative ranks. Absolute and relative mobility often diverge.

Childhood Family Instability and Young-Adult Union Experiences: Black-White Differences in Outcomes and Effects.

Today's young adults have diverse union experiences; some enter enduring marital or cohabiting unions at young ages, but many delay or dissolve their unions or remain single. Childhood family instability-defined as parents' transitions into or out of romantic coresidential unions-offers one explanation for why some people are more likely than others to enter and exit unions. We evaluate whether this family instability hypothesis-a union-specific version of the general hypothesis that instability affects people across multiple life domains-can explain Black and White young adults' union formation and dissolution.

Is the Effect Larger in Group A or B? It Depends: Understanding Results From Nonlinear Probability Models.

Demographers and other social scientists often study effect heterogeneity (defined here as differences in outcome-predictor associations across groups defined by the values of a third variable) to understand how inequalities evolve between groups or how groups differentially benefit from treatments. Yet answering the question "Is the effect larger in group A or group B?" is surprisingly difficult. In fact, the answer sometimes reverses across scales.

Ankle Arthroscopy as an Adjunct to the Management of Ankle Fractures.

Background: Ankle fractures are one of the most common injuries managed by orthopedic surgeons. Although the etiology of posttraumatic osteoarthritis in anatomically reduced ankle fractures is not completely known, several studies suggest that undetected intra-articular pathology at the time of injury may play a role. The purpose of this study is to report the operative findings of ankle arthroscopy as an adjunct to ankle fracture open reduction and internal fixation.

Marriage and Union Formation in the United States: Recent Trends Across Racial Groups and Economic Backgrounds.

Family formation in the United States has changed dramatically: marriage has become less common, nonmarital cohabitation has become more common, and racial and economic inequalities in these experiences have increased. We provide insights into recent U.S.
