Population Research and Policy Review - The current study examines the association between social context and the formation of same-sex coresidential unions, with a particular focus on sexual...     

A new look at Markov processes of G/M/1-type

We present a new method for deriving the stationary distribution of an ergodic Markov process of G/M/1-type in continuous-time, by deriving and making use of a new representation for each element of the rate matrices contained in these distributions. This method can also be modified to derive the Laplace transform of each transition function associated with Markov processes of G/M/1-type.     

Body Weight and Matching With a Physically Attractive Romantic Partner

Matching and attribute trade are two perspectives used to explain mate selection. We investigated patterns of matching and trade, focusing on obesity, using Add Health Romantic Pair data (N = 1,405 couples). Obese individuals, relative to healthy weight individuals, were less likely to have physically attractive partners, with this disadvantage greater for women than men, and greater for White women than Black women. Additional education, a more attractive personality, and better grooming increased the probability of having a physically attractive partner and offset the disadvantage of obesity for some individuals. Unexpectedly, we found women, like men, trade education for their partners’ physical attractiveness. Despite evidence of attribute trade, matching with respect to physical characteristics was the dominant mate selection pattern.     

Emotional Satisfaction and Physical Pleasure in Sexual Unions: Time Horizon,Sexual Behavior,and Sexual Exclusivity

This paper uses data from the 1992 National Health and Social Life Survey to examine emotional satisfaction and physical pleasure from sex in intimate unions for adults in the U.S. Using perspectives from evolutionary biology and rational choice theory, we examine the effects of the following factors on emotional satisfaction and physical pleasure: time horizon expected for the relationship, sexual behavior within the relationship, and sexual exclusivity. We find a significant effect of measures for all 3 of these dimensions on emotional satisfaction with sex. For both men and women, time horizon and sexual exclusivity are more strongly tied to emotional satisfaction than they are to physical pleasure from sex, but sexual behavior has the same impact on emotional satisfaction as it does on physical pleasure.     

You don't bring me anything but down: adolescent romance and depression

What accounts for the sex difference in depression that emerges during the period of adolescence? We propose that females become more depressed than males in adolescence partly as a consequence of their involvement in romantic relationships. Using two waves of data from the National Longitudinal Study of Adolescent Health (N = 8,181), a study which began interviewing respondents in 1994, we compare change in levels of depression for adolescents with and without romantic involvement between interviews. Our results suggest that males and females who become romantically involved between interviews experience a larger increase in depression than their counterparts who do not; however, females experience a larger increase in depression than males in response to romantic involvement. Our results suggest that females' greater vulnerability to romantic involvement explains a large part of the emerging sex difference in depression during adolescence.     

Social Exchange and The Progression of Sexual Relationships in Emerging Adulthood

Research has extensively examined matching on race and other characteristics in cohabitation and marriage, but it has generally disregarded sexual and romantic relationships. Using data from the 2002 National Survey of Family Growth and the National Longitudinal Study of Adolescent Health, we examine the tempo of key transitions in the recent relationships of young adults aged 18 to 24. We focus on how the racial mix of partners in relationships is associated with the timing to sex, cohabitation, and marriage. We find evidence that relationships between white men and minority women proceed more rapidly than relationships involving other racial combinations from romance to sexual involvement and from sexual involvement to cohabitation. Our findings have important implications for social exchange perspectives on mate selection.     

Do Hispanic and Asian Adolescents Practice Panethnicity in Friendship Choices?*

Objectives. Using data from the National Longitudinal Study of Adolescent Health (Add Health), we investigate whether Asian and Latino youth value racial boundaries more than ethnic boundaries. We evaluate the relative preferences of same‐ethnic, same‐race (but different‐ethnic), and different‐race friends. Methods. We use multilevel multinomial logistic regression models to examine the odds of choosing same‐ethnic, different‐ethnic (but same‐race), and different‐race friends net of the opportunity to interact. Results. We find strong effects of school racial and ethnic composition, immigrant status, and parental education on the likelihood of crossing boundaries in the selection of friends. In addition, we develop a new scale of panethnicity and find substantial ethnic group variation in panethnic sentiment. Conclusion. We find an overwhelming preference for same‐ethnic peers over same‐race (different‐ethnic) and different‐race peers.     

The Quality of Male Fertility Data in Major U.S. Surveys

Researchers continue to question fathers’ willingness to report their biological children in surveys and the ability of surveys to adequately represent fathers. To address these concerns, this study evaluates the quality of men’s fertility data in the 1979 and 1997 cohorts of the National Longitudinal Survey of Youth (NLSY79 and NLSY97) and in the 2002 National Survey of Family Growth (NSFG). Comparing fertility rates in each survey with population rates based on data from Vital Statistics and the U.S. Census Bureau, we document how the incomplete reporting of births in different surveys varies according to men’s characteristics, including their age, race, marital status, and birth cohort. In addition, we use Monte Carlo simulations based on the NSFG data to demonstrate how birth underreporting biases associations between early parenthood and its antecedents. We find that in the NSFG, roughly four out of five early births were reported; but in the NLSY79 and NLSY97, almost nine-tenths of early births were reported. In all three surveys, incomplete reporting was especially pronounced for nonmarital births. Our results suggest that the quality of male fertility data is strongly linked to survey design and that it has implications for models of early male fertility.     

DO RACE AND ETHNICITY MATTER AMONG FRIENDS?

Using the National Longitudinal Study of Adolescent Health (or Add Health), a nationally representative sample of adolescents in 1994–1995, we examine if and how friendship activities differ among interracial, interethnic, and interethnic friendships of white, black, Hispanic, and Asian youths. We find that best friends are more likely than higher-order friends to be from the same ethnic group and that best friends report more shared activities during the past week than do their higher-order friendship counterparts. Hence, we argue that shared activities is a useful indicator of friendship intimacy. In general, interracial friends report fewer shared activities than do intraracial friends, although this difference is strongest for white respondents. Moreover, we find that white, Asian, and Hispanic youths all report fewer activities with their black friends. We find little difference in friendship activities between interethnic and intraethnic friendships. Our findings suggest that, even when youths manage to break racial boundaries in friendship selection, these friendships face greater challenges than do those between individuals of the same race.     

Gender and the Stability of Same-Sex and Different-Sex Relationships Among Young Adults

Most research on the stability of adult relationships has focused on coresidential (cohabiting or married) unions and estimates rates of dissolution for the period of coresidence. Studies examining how the stability of coresidential unions differs by sex composition have typically found that same-sex female couples have higher rates of dissolution than same-sex male couples and different-sex couples. We argue that the more elevated rates of dissolution for same-sex female couples are a by-product of the focus on coresidential unions. We use data from the National Longitudinal Study of Adolescent to Adult Health to compare rates of dissolution based on the total duration of romantic and sexual relationships for same-sex male couples, same-sex female couples, and different-sex couples. Results from hazard models that track the stability of young adult relationships from the time they are formed demonstrate that male couples have substantially higher dissolution rates than female couples and different-sex couples. Results based on models restricted to the period of coresidence corroborate the counterintuitive finding from earlier studies that female couples have the highest rates of dissolving coresidential unions. This study underlines the importance of comparisons between these couple types for a better understanding of the role that institutions and gender play in the stability of contemporary relationships.
