Title: Differential fertility makes society more conservative on family values
Data from the General Social Survey indicate that higher-fertility individuals and their children are more conservative on “family values” issues, especially regarding abortion and same-sex marriage. This pattern implies that differential fertility has increased and will continue to increase public support for conservative policies on these issues. The association of family size with conservatism is specific to traditional-family issues and can be attributed in large part to the greater religiosity and lower educational attainment of individuals from larger families. Over the 2004 to 2018 period, opposition to same-sex marriage and abortion was 3 to 4 percentage points more prevalent than it would have been were traditional-family conservatism independent of family size in the current generation. For same-sex marriage, evolutionary forces have grown in relative importance as society as a whole has liberalized. As of 2018, differential fertility raised the number of US adults opposed to same-sex marriage by 17%, from 46.9 million to 54.8 million.  more » « less

  1. This study examines the idea that attitudes toward marriage are liberalizing in the US in the face of federal recognition of same-sex marriage legislation by examining attitudes toward conventional marriage ideals, same-sex marriage, and polyamorous marriage. It draws on a sample of liberal arts college students (n = 330) in the southeastern United States as a representation of a cohort more flexible to change and greater social tolerance. Findings indicate shifts away from conventional marriage and toward marriage as more inclusive of same-sex couples. At the same time, less than half support polyamorous marriage. Unsurprisingly, religious students are more likely to support conventional marriage ideals and less likely to support same-sex marriage and students with conservative political ideology are less likely to support same-sex marriage or polyamorous marriage. In particular, the negative impact of political ideology on these attitudes is stronger for men and straight students. Women are more likely than men to support same-sex marriage. LGBQ students are less likely to support conventional views of marriage and more likely to support polyamorous marriage than heterosexual students. While college students today have entered adulthood in the age of marriage equality, and are accepting of same-sex unions, students indicate more mixed feelings about what marriage encompasses, the value of marriage, and whether to support polyamorous marriage.

  2. ImportanceAbortion bans may lead to births among those who are unable to overcome barriers to abortion. The population-level effects of these policies, particularly their unequal impacts across subpopulations in the US, remain unclear. ObjectiveTo assess heterogeneity in the association of abortion bans with changes in fertility in the US, within and across states. Design, Setting, and ParticipantsDrawing from birth certificate and US Census Bureau data from 2012 through 2023 for all 50 states and the District of Columbia, this study used a bayesian panel data model to evaluate state-by-subgroup-specific changes in fertility associated with complete or 6-week abortion bans in 14 US states. The average percent and absolute change in the fertility rate among females aged 15 through 44 years was estimated overall and by state, and within and across states by age, race and ethnicity, marital status, education, and insurance payer. ExposureComplete or 6-week abortion ban. Main outcome and MeasuresFertility rate (births per 1000 reproductive-aged females) overall and by subgroups. ResultsThere were an estimated 1.01 (95% credible interval [CrI], 0.45-1.64) additional births above expectation per 1000 females aged 15 through 44 years (reproductive age) in states following adoption of abortion bans (60.55 observed vs 59.54 expected; 1.70% increase; 95% CrI, 0.75%-2.78%), equivalent to 22 180 excess births, with evidence of variation by state and subgroup. Estimated differences above expectation were largest for racially minoritized individuals (≈2.0%), unmarried individuals (1.79%), individuals younger than 35 years (≈2.0%), Medicaid beneficiaries (2.41%), and those without college degrees (high school diploma, 2.36%; some college, 1.58%), particularly in southern states. Differences in race and ethnicity and education across states explain most of the variability in the state-level association between abortion bans and fertility rates. Conclusion and RelevanceThese findings provide evidence that fertility rates in states with abortion bans were higher than would have been expected in the absence of these policies, with the largest estimated differences among subpopulations experiencing the greatest structural disadvantages and in states with among the worst maternal and child health and well-being outcomes.

  3. The deinstitutionalization of marriage suggests more support for divorce and the forgoing of marriage. In this study, we examine attitudes toward both marriage and divorce in the context of having children and how they coincide with each other, creating a new typology of attitudes. Based on a national probability sample of 2,789 adults from the American Marriage Survey conducted in 2021, we find that just over half (55%) of people express transformative deinstitutionalization attitudes, in which they support divorce as well as forgoing marriage, while the next largest group (22%) hold divorce deinstitutionalization attitudes, in which they support divorce but also encourage marriage when children are involved. Findings show that women, gay, lesbian, bisexual, and pansexual individuals, and those who are cohabiting or divorced are more likely to hold transformative deinstitutionalization attitudes compared to pro-institutionalization attitudes, which support marriage and oppose divorce when children are involved. Meanwhile, older individuals, those who attend religious services more frequently, and those who identify as more politically conservative are less likely to hold any form of deinstitutionalization attitudes. Interestingly, education and parenthood have no impact on this set of attitudes. Given trends that show decreases in marriage and increases in LGBT identification, there may be further movement toward the disconnection of marriage and children.

  4. Scholars have long questioned whether and how courts influence society. We contribute to this debate by investigating the ability of judicial decisions to shape issue attention and affect toward courts in media serving the LGBTQ+ community. To do so, we compiled an original database of LGBTQ+ magazine coverage of court cases over an extended period covering major decisions, includingLawrence v. Texas(2003),Goodridge v. Massachusetts Department of Public Health(2003), andLofton v. Secretary of Department of Children & Family Services(2004). We argue these cases influence the volume and tone of LGBTQ+ media coverage. Combining computational social science techniques with qualitative analysis, we find increased attention to same-sex marriage after the decisions inLawrence,Goodridge, andLofton,and the coalescence of discussions of courts around same-sex marriage afterLawrence.We also show how LGBTQ+ media informed readers about the political and legal implications of struggles over marriage equality.

  5. Behavior is often linked to gonadal sex; however, ecological or social environments can induce plasticity in sex-biased behaviors. In biparental species, pairs may divide offspring care into two parental roles, in which one parent specializes in territory defense and the other in nest care. The African cichlid fish Julidochromis marlieri displays plasticity in sex-biased behaviors. In Lake Tanganyika, J. marlieri form female-larger pairs in which the female is more aggressive than the male who performs more nest care, but under laboratory conditions, male-larger pairs can be formed in which these sex-biased behaviors are reversed. We investigated the influence of social environment on behavior by observing how individuals in both pair-types respond to conspecific intruders of either sex. We examined behavioral responses to three factors: sex of the subject, relative size of the subject, and the sex of the intruder. We confirm that relative size is a factor in behavior. The larger fish in the pair is more aggressive than the smaller fish is towards an intruder. While neither fish in the female-larger pairs varied their behaviors in response to the sex of the intruder, both members of the male-larger pairs were sensitive to intruder sex. Both individuals in the male-larger pairs engaged in more biting behaviors towards the intruder. Intruder biting behaviors strongly correlated with the biting behavior of the larger individual in the pair and occurred more frequently when encountering pairs with same sex as the larger fish when compared to pairs with the same sex as the smaller fish. Our results support the role of the social environment as a contributor in the expression of sex-biased behavior.
