Understanding How Immigrant Fertility Differentials Vary over the Reproductive Life Course

Forced Migration and the Childbearing of Women and Men: A Disruption of the Tempo and Quantum of Fertility?

It is well known that migrant fertility is associated with age at migration, but little is known about this relationship for forced migrants. We study an example of displacement in which the entire population of Finnish Karelia was forced to move elsewhere in Finland in the 1940s. This displacement was unique because of its size and scale, because we have data on almost the whole population of both men and women who moved, and because of the similarity between origin and destination. These aspects enable us to investigate the disruptive impact of forced migration, net of other factors such as adaptation and selection. For all ages at migration from one to 20, female forced migrants had lower levels of completed fertility than similar women born in present-day Finland, which suggests a permanent impact of migration. However, women born in the same year as the initial forced migration showed no difference, which may indicate the presence of a counterbalancing fertility-increasing effect, as observed elsewhere for people born during a humanitarian crisis. There is less evidence of an impact for men, which suggests a gendered impact of forced migration-and its timing-on fertility. Results are similar after controlling for social and spatial mobility, indicating that there may be no major trade-off between reproduction and these forms of mobility.

Nativity differentials in first births in the United States: Patterns by race and ethnicity

BACKGROUND

While recent decades have seen gradual convergence in ethno-racial disparities in completed fertility in the United States, differences in the age pattern of first births remain. The role of nativity has not been fully understood.

OBJECTIVE

This paper examines how first births vary by nativity, and how this variation contributes to more significant racial and ethnic differentials.

METHODS

Using data from the National Survey of Family Growth (1997-2017), we jointly estimate the correlates of the timing of first births and childlessness. We assess differences between immigrants and US-born and child-migrant women across ethno-racial groups.

RESULTS

The unique first-birth patterns among foreign-born women have a notable impact on Hispanics, reducing differences from Whites in the average age at first birth and contributing to more significant differentials in childlessness. The impact of immigrant women on White and Black first births is more modest in scope.

CONTRIBUTION

Our work shows the importance of nativity for ethnic/racial disparities in the timing and quantum of fertility in the United States. We demonstrate how the migrant population is more determinant for Hispanic fertility patterns than for Black or White. We conclude by elaborating on the implications of these results for future research as the immigrant population in the United States becomes ethnically and racially more diverse.

The Fertility of Immigrants From Low-Fertility Settings: Adaptation in the Quantum and Tempo of Childbearing?

Immigrant women who have lived longer in a destination often have relatively low levels of fertility, which is sometimes taken as evidence of the adaptation of behavior. This evidence is almost exclusively based on studies of immigrants from high-fertility settings, while the fertility of immigrants from low-fertility settings has been largely overlooked. Research has also rarely studied the fertility of immigrants who migrated as children, despite the methodological advantages of applying such an approach. This study focuses on women who grew up in Sweden with a migration background from low-fertility origins. We expect that Sweden's welfare regime makes it easier for women to combine childbearing and working life, regardless of migration background, thereby facilitating an adaptation of fertility behavior toward that prevailing in Sweden. We find evidence of adaptation in terms of birth timing for at least half of the country-origin groups that we study, but very little evidence of adaptation in terms of completed fertility. Further, we find that, in comparison with ancestral Swedes, completed fertility differentials are larger for second-generation individuals than for immigrants who arrived during childhood. This is evidence against the notion of "straight-line" adaptation for immigrants and the children of immigrants who are born in Sweden.

Differences in Abortion Rates between Asian Populations by Country of Origin and Nativity Status in New York City, 2011-2015

Despite the size of the Asian population in New York City (NYC) and the city’s robust abortion surveillance system, abortion-related estimates for this population have not been calculated previously. This study examined the use of abortion services among specific Asian groups in NYC from 2011–2015. Using NYC surveillance data, we estimated abortion rates for Asians, disaggregated by five country of origin groups and nativity status, and for other major racial/ethnic groups. We compared rates between groups and over time. From 2014–2015, the abortion rate for Asian women in NYC was 12.6 abortions per 1000 women aged 15–44 years, lower than the rates for other major racial/ethnic groups. Among country of origin groups, Indian women had the highest rate (30.5 abortions per 1000 women), followed by Japanese women (17.0), Vietnamese women (13.0), Chinese women (8.8), and Korean women (5.1). Rates were higher for U.S.-born Asian groups compared to foreign-born groups, although the differential varied by country of origin. The abortion rate declined or remained steady for nearly all Asian groups from 2011–2015. These findings reinforce the importance of disaggregating data on this population at multiple levels and begin to provide much-needed evidence on the use of abortion services among Asian groups.

Visualising Immigrant Fertility -- Profiles of Childbearing and their Implications for Migration Research

Different measures of fertility have strengths and limitations when used to describe the fertility of immigrants, and no single measure captures every aspect of this complex phenomenon. This paper introduces a novel visual framework that shows life course profiles of immigrant childbearing in a multifaceted way. It develops the well-known cohort fertility curve—showing the average number of children ever born over the life course—and adds lines for immigrant women arriving at different ages, using their average number of children born on arrival as a starting point. These immigrant fertility profiles can illustrate a number of important aspects of childbearing simultaneously, including children born before arrival, fertility after arrival and completed fertility at the end of childbearing. In addition to showing numbers of children born (i.e. fertility quantum), the slopes of each profile indicate the tempo of fertility and how this changes by age and duration of residence. The fertility profiles of different immigrant groups can be plotted in the same graph, and can be compared and contrasted with non-immigrant groups—at origin as well as destination—through the augmentation of each visualisation. Using Nordic register data, we illustrate how these fertility profiles can be used to expand our knowledge of immigrant childbearing and to investigate various hypotheses of migrant fertility, giving a novel overview of the relationships between fertility measures such as period and quantum, before and after arrival.
