The share of young adults living in married-couple family households in the USA has declined in recent decades. Research on alternative living arrangements focuses on cohabitation among unmarried couples and parent-adult child coresidence. Less is known about trends in non-family living arrangements and the characteristics of young adults living with non-relatives. This study documents trends over time in non-family living arrangements among young adults in the USA and examines the sociodemographic profile of those living with non-relatives. Using pooled US Census and American Community Survey microdata from 1990 to 2019, the authors document age patterns in non-family living arrangements over time and use logistic regression to estimate the likelihood of living with non-family based on individual-level characteristics. Results indicate that non-family living among young adults has increased over time, and that the arrangement is associated with markers of both advantage and disadvantage. Differences across age groups explain some of these mixed results. Trends among younger groups are linked to socioeconomic patterns around family formation. Among older groups, the demographic and labor force characteristics of the foreign born and constraints of their kin availability may be driving trends. The exploratory analysis provides relevant evidence around an increasingly common living arrangement in the USA and also identifies several areas for future research on living arrangements among young adults and the implications of these trends.

近几十年来,美国生活在已婚夫妇家庭中的年轻成年人比例有所下降。有关替代性生活安排的研究主要集中在未婚夫妇同居和父母与成年子女同住方面。至于非家庭生活安排的趋势以及与非亲属生活在一起的年轻成年人的特点,人们所知甚少。本研究记录了美国青壮年非家庭居住安排的长期趋势,并考察了与非亲属同住的青壮年的社会人口特征。作者利用 1990 年至 2019 年美国人口普查和美国社区调查的汇总微观数据,记录了不同时期非家庭生活安排的年龄模式,并使用逻辑回归估计了基于个人层面特征的非家庭生活可能性。结果表明,随着时间的推移,青壮年中的非家庭生活有所增加,而且这种安排与优势和劣势的标志物都有关联。不同年龄组的差异解释了其中一些好坏参半的结果。年轻群体的趋势与围绕组建家庭的社会经济模式有关。在年龄较大的群体中,外国出生者的人口和劳动力特征以及其亲属可用性的限制可能是趋势的驱动因素。探索性分析围绕美国日益普遍的生活安排提供了相关证据,同时也确定了未来研究青壮年生活安排的几个领域以及这些趋势的影响。

We use longitudinal data on religious affiliation in Finland to examine childbearing behavior. All analyses are based on detailed fertility information from the Finnish national register of each person's religious denomination for men and women born in 1956-1975. We identify higher fertility according to parity among members of the Evangelical Lutheran state church and other Protestant churches, and lower fertility among individuals with no religious affiliation. Most other religious groups-Orthodox Christians, Jews, Muslims, and adherents of Eastern religions-have intermediate levels of fertility. We also find that religious converts, that is, those observed with more than one religious denomination over their life course, typically are similar to the non-converts of the group they convert to, though with more distinct deviations from the Finnish population. Women show larger differences by religious affiliation than men. We find the largest differences across religions when we examine the proportion of childless men and women. Overall, differences between religious groups are rather modest, and childbearing patterns are quite similar. Our results provide, to our knowledge, the first examination of religion and fertility using national-level longitudinal data.

我们利用芬兰宗教信仰的纵向数据来研究生育行为。所有分析都基于芬兰国家登记册中关于 1956-1975 年出生的男性和女性每个人宗教派别的详细生育信息。我们发现,福音路德教派(Evangelical Lutheran)国教和其他新教教徒的生育率较高,而无宗教信仰者的生育率较低。大多数其他宗教团体--东正教、犹太教、穆斯林和东方宗教信徒--的生育率处于中等水平。我们还发现,宗教皈依者,即那些在一生中被观察到拥有一个以上宗教派别的人,通常与他们所皈依的群体中的非皈依者相似,但与芬兰人口的偏差更为明显。与男性相比,女性在宗教信仰上的差异更大。当我们研究无子女男性和女性的比例时,我们发现不同宗教之间的差异最大。总体而言,不同宗教团体之间的差异不大,生育模式也十分相似。据我们所知,我们的研究结果首次利用国家级纵向数据对宗教和生育率进行了研究。

Self-Perceived Infertility is Not Always Associated with Having Fewer Children: Evidence from German Panel Data. 自认不育并非总是与少子化相关:来自德国面板数据的证据。

Proximate determinants theory considers infertility rates a risk factor for lower fertility rates, but the assumption that people who perceive infertility will have fewer children has not been tested. This study investigates the association of self-perceived infertility with the number of children people have had after 11 years. Infertility implies reduced chances of conception (rather than sterility), but people do not always consistently perceive infertility over time. If people who think they are infertile at one time can later report no infertility, then does self-perceived infertility necessarily lead to having fewer children? We answer this question by analyzing 11 waves of the German family panel (pairfam) data using negative binomial growth curve models for eight core demographic subgroups created by combinations of gender (men/women), parity (0/1+children), and initial age groups (25-27 and 35-37). Those who repeatedly perceived themselves to be infertile (three times or more) had fewer children than those who perceived themselves to be infertile once or twice in only four of eight gender by initial parity by age groups. Only in four groups did people who perceived themselves to be infertile once or twice have fewer children than those who never perceived themselves to be infertile in both the unadjusted and adjusted models. Thus, self-perceived infertility does not necessarily result in fewer children. Rather, the association depends upon life course context and gender.

近因决定理论认为不孕不育率是导致生育率降低的一个风险因素,但认为不孕不育的人会少生育子女的假设尚未得到验证。本研究调查了自我感觉不育与 11 年后生育子女数量的关系。不育意味着受孕机会减少(而不是不育),但人们对不育的看法并不总是长期一致的。如果在某一时期认为自己不育的人后来又报告说自己没有不育,那么自我感觉不育是否一定会导致少生孩子呢?我们使用负二叉增长曲线模型分析了 11 波德国家庭面板(pairfam)数据,针对由性别(男性/女性)、均龄(0/1+子女)和初始年龄组(25-27 岁和 35-37 岁)组合而成的八个核心人口亚组,回答了这个问题。在按性别、初始奇偶数和年龄分组的八个组别中,多次认为自己不育(三次或三次以上)的人的子女数仅在四个组别中少于认为自己不育一次或两次的人。在未调整模型和调整模型中,只有四组认为自己不育一次或两次的人比从未认为自己不育的人子女少。因此,自我感觉不育并不一定会导致子女减少。相反,这种关联取决于生活过程的背景和性别。

This paper is the first to examine to what extent ethnicity affects ever migrating and the number of migrations across the lifespan for the case of internal migration in Indonesia. We use all five waves of the Indonesia Family Life Survey (IFLS) to study migration behaviour of respondents belonging to some of the largest ethnic groups in Indonesia. Our logistic regression results show that the Minangkabau, Betawi, Madurese, Balinese, Buginese and Makassarese, and Sasak, Bima and Dompu are less likely to ever migrate than the Javanese. Using only migrants and controlling for the first migration and other characteristics, truncated negative binomial regression results show that, in comparison with the Javanese, the Minangkabau and Banjarese have a higher expected number of migrations while the numbers are lower for the Betawi and Balinese. Thus, ethnicity contributes to ever migrating as well as the number of migrations, but we find that the differences between the ethnic groups diminish for the latter. These results also point out that a higher likelihood of ever migrating does not always correspond with a higher number of migrations, highlighting the importance of studying migration count to complement the study of migration as a one-time event.

本文首次以印度尼西亚国内移民为例,研究了种族在多大程度上影响曾经移民和一生中的移民次数。我们利用印尼家庭生活调查(IFLS)的全部五次波次,研究了属于印尼一些最大族群的受访者的移民行为。我们的逻辑回归结果显示,米南卡保、贝塔维、马都拉、巴厘、布吉、马卡萨雷、萨萨克、比马和东布族比爪哇族更不可能移徙。仅使用移民并控制首次移民和其他特征,截断负二项回归结果显示,与爪哇人相比,米南卡保人和班贾瑞人的预期移民次数较高,而贝塔维人和巴厘人的预期移民次数较低。因此,民族因素对曾经移民和移民次数都有影响,但我们发现,就后者而言,各民族之间的差异有所减小。这些结果还指出,曾经移徙的可能性越高,移徙次数就越多,这突出了研究移徙次数的重要性,以补充将移徙作为一次性事件的研究。

The Impact of Education on Fertility During the Chinese Reform Era (1980-2018): Changes Across Birth Cohorts and Interaction with Fertility Policies. 中国改革时期(1980-2018 年)教育对生育率的影响:不同出生组群的变化以及与生育政策的相互作用》,中国人民大学出版社,2011 年。

We examined the influence of education on fertility decisions in contemporary China, drawing upon theoretical insights that emphasise the role of social institutions, gender relations, and life course dynamics in shaping family behaviour. This led us to propose a set of hypotheses that explain the differential effect of education on each parity. We used information on female cohorts born between 1960 and 1989, coming from the China Family Panel Studies for 2010-2018. We applied event history models with both independent and simultaneous equations models to account for selection and endogeneity effects. The results point to a substantial contribution of the increased educational attainment in the population in the fertility decline and current low levels of fertility, beyond the role of fertility policies. Consistent with our hypotheses, the results show that woman's educational attainment has a strong negative effect on the hazard of bearing a second or third child. Male partner's educational attainment also has a negative effect on the hazard of transition to a second or third birth, yet with a weaker intensity. We also found that the negative effect of education on second birth rates significantly declines across birth cohorts. The results show little educational differentials in the probability of bearing a first child, while the better educated postpone first births. Moreover, the effect of fertility policies, measured at the individual level, gradually increases with the level of education.

我们研究了教育对当代中国生育决定的影响,并借鉴了强调社会制度、性别关系和生命历程动态在塑造家庭行为中的作用的理论观点。这促使我们提出了一系列假设,以解释教育对每个均等的不同影响。我们使用了 2010-2018 年中国家庭面板研究中关于 1960 年至 1989 年出生的女性群体的信息。我们采用了独立方程和同步方程的事件史模型,以考虑选择和内生效应。结果表明,在生育政策的作用之外,人口受教育程度的提高对生育率下降和目前的低生育率水平也有很大贡献。与我们的假设一致,结果表明妇女的教育程度对生育第二或第三个孩子的风险有很大的负面影响。男性伴侣的受教育程度对生育第二或第三个孩子的风险也有负面影响,但强度较弱。我们还发现,在不同的出生组群中,教育对二胎生育率的负面影响显著下降。结果显示,生育第一胎的概率几乎没有教育差异,而教育程度较高的人则会推迟生育第一胎。此外,从个人层面衡量,生育政策的影响随着教育水平的提高而逐渐增大。

Spatial assimilation theory asserts that immigrants' socioeconomic progress leads to residential adaptation and integration. This association has proven robust in USA and European urban areas through much of the twentieth century, but drastic change of ethnic and class compositions yet persistent (neighbourhood) inequality in the urban landscape urge us to reconsider the dynamic interaction between stability and change. In this study, we investigate to what extent education shapes residential mobility differently for young adults with varying ethnic and social origins. Focussing on Brussels, we use multinomial logistic regressions on linked longitudinal population-based censuses from 1991 and 2001 and register data for the period 2001-2006. Analyses show that dispersal away from poor inner-city neighbourhoods appears least likely for the offspring of poor low-educated non-Western households, regardless of their own educational attainment. While our approach roughly confirms traditional arguments of socio-spatial integration, it also reveals how educational success generates opportunities to escape poor neighbourhoods for some but not for others. With this, it points at the subtle ways in which factors and mechanisms in traditional spatial assimilation theory affect residential behaviour of young adults over their life course, at the intersection of specific locales, ethnic groups, social classes and generations.

空间同化理论认为,移民的社会经济进步会导致居住地的适应和融合。在 20 世纪的大部分时间里,这种关联在美国和欧洲城市地区被证明是强有力的,但种族和阶级构成的急剧变化以及城市景观中持续存在的(邻里)不平等促使我们重新考虑稳定与变化之间的动态互动。在本研究中,我们调查了教育在多大程度上影响了不同种族和社会出身的年轻人的居住流动性。我们以布鲁塞尔为研究对象,对 1991 年和 2001 年的纵向人口普查数据以及 2001-2006 年的登记数据进行了多项式逻辑回归分析。分析表明,对于贫困的低学历非西方家庭的后代而言,无论其自身的教育程度如何,他们似乎最不可能从贫困的市中心街区分散出去。我们的研究方法大致证实了社会空间融合的传统论点,同时也揭示了教育成功是如何为一些人创造了逃离贫困街区的机会,而对另一些人则不然。因此,它指出了传统空间同化理论中的因素和机制在特定地区、种族群体、社会阶层和世代交替中影响年轻成年人一生居住行为的微妙方式。

Fertility Declines Near the End of the COVID-19 Pandemic: Evidence of the 2022 Birth Declines in Germany and Sweden. COVID-19大流行即将结束时的生育率下降:德国和瑞典 2022 年出生率下降的证据。

Following the onset of the COVID-19 pandemic, many countries faced short-term fertility declines in 2020-2021, a development which did not materialize in the majority of German-speaking and Nordic countries. However, more recent birth statistics show a steep fertility decline in 2022. We aim to provide empirical evidence on the unexpected birth decline in 2022 in Germany and Sweden. We rely on monthly birth statistics and present seasonally adjusted monthly Total Fertility Rates (TFR) for Germany and Sweden. We relate the nine-month lagged fertility rates to contextual developments regarding COVID-19. The seasonally adjusted monthly TFR of Germany dropped from 1.5-1.6 in 2021 to 1.4 in early 2022 and again in autumn 2022, a decline of about 10% in several months. In Sweden, the corresponding TFR dropped from about 1.7 in 2021 to 1.5-1.6 in 2022, a decline of almost 10%. There is no association of the fertility trends with changes in unemployment, infection rates, or COVID-19 deaths, but a strong association with the onset of vaccination programmes and the weakening of pandemic-related restrictions. The fertility decline in 2022 in Germany and Sweden is remarkable. Common explanations of fertility change during the pandemic do not apply.

COVID-19 大流行爆发后,许多国家在 2020-2021 年面临生育率短期下降的问题,但大多数德语国家和北欧国家并未出现这种情况。然而,最近的出生统计数据显示,2022 年的生育率急剧下降。我们旨在为德国和瑞典 2022 年出生率意外下降提供经验证据。我们依据月度出生统计数据,提出了德国和瑞典经季节调整的月度总和生育率(TFR)。我们将滞后 9 个月的生育率与 COVID-19 的背景发展联系起来。德国经季节调整的月总和生育率从 2021 年的 1.5-1.6 降至 2022 年初的 1.4,并在 2022 年秋季再次下降,几个月内下降了约 10%。在瑞典,相应的总生育率从 2021 年的约 1.7 降至 2022 年的 1.5-1.6,降幅接近 10%。生育率趋势与失业率、感染率或 COVID-19 死亡人数的变化没有关联,但与疫苗接种计划的启动和与大流行相关的限制措施的减弱密切相关。德国和瑞典 2022 年的生育率下降非常明显。大流行期间生育率变化的常见解释并不适用。大规模疫苗接种的开始与随后生育率下降之间的联系表明,妇女调整了行为,在怀孕前接种疫苗。随着社会开放,生活条件更加正常化,生育率也随之下降。我们提供了有关大流行期间和之后生育率下降以及 COVID-19 与生育率关系的新信息。

However, more recent birth statistics show a steep fertility decline in 2022. We aim to provide empirical evidence on the unexpected birth decline in 2022 in Germany and Sweden. We rely on monthly birth statistics and present seasonally adjusted monthly Total Fertility Rates (TFR) for Germany and Sweden. We relate the nine-month lagged fertility rates to contextual developments regarding COVID-19. The seasonally adjusted monthly TFR of Germany dropped from 1.5-1.6 in 2021 to 1.4 in early 2022 and again in autumn 2022, a decline of about 10% in several months. In Sweden, the corresponding TFR dropped from about 1.7 in 2021 to 1.5-1.6 in 2022, a decline of almost 10%. There is no association of the fertility trends with changes in unemployment, infection rates, or COVID-19 deaths, but a strong association with the onset of vaccination programmes and the weakening of pandemic-related restrictions. The fertility decline in 2022 in Germany and Sweden is remarkable. Common explanations of fertility change during the pandemic do not apply.

Despite increasing diversity within many societies, ethnically endogamous unions remain common. In contexts where one ethnic minority has lived alongside the majority for centuries, understanding who partners with whom is central to understanding how ethnic boundaries are maintained or dissolved. This study examines the role of own and parental ethnolinguistic affiliation for the first partner choice in Finland. We provide a unique test of the relevance of ethnic endogamy across two generations, in a context where both groups are native, but one (Finnish speakers) overwhelmingly outnumbers the other (Swedish speakers). Using register data on the total population, we examine how a person's ethnolinguistic affiliation and background affect the choice of the first cohabiting partner in terms of the partner's ethnolinguistic affiliation and background. We apply discrete-time competing risk models for men and women born 1970-1983. Results indicate that Swedish-registered individuals with two Swedish-registered parents are, by far, the most likely to partner with another Swedish-registered person with endogamous background. Partnering with a Swedish-registered person with exogamous background is most likely among individuals who themselves come from mixed unions. Patterns are remarkably consistent across gender, and adjustments for education and residential area only marginally alter the results.

尽管许多社会的多样性日益增加,但种族间的一夫一妻制仍然很普遍。在一个少数民族与多数民族共同生活了几个世纪的情况下,了解谁与谁结为伴侣对于了解民族界限是如何维持或消解的至关重要。本研究探讨了在芬兰,自己和父母的民族语言归属对第一伴侣选择的影响。在两个群体都是本地人,但其中一个群体(讲芬兰语的群体)的人数压倒性地超过另一个群体(讲瑞典语的群体)的情况下,我们对两代人之间的种族内婚的相关性进行了独特的检验。我们利用总人口的登记数据,研究了一个人的民族语言归属和背景如何影响其对第一位同居伴侣的民族语言归属和背景的选择。我们对 1970-1983 年出生的男性和女性采用了离散时间竞争风险模型。结果表明,到目前为止,父母双方都是瑞典户籍的瑞典人最有可能与另一个具有内婚背景的瑞典户籍的人成为伴侣。而与具有外婚背景的瑞典户籍人士建立伴侣关系的可能性最大的是那些本身就来自混合婚姻的人士。不同性别之间的模式非常一致,对教育程度和居住地区的调整只对结果产生微小的影响。

Sequence analysis is employed in different fields-e.g., demography, sociology, and political sciences-to describe longitudinal processes represented as sequences of categorical states. In many applications, sequences are clustered to identify relevant types, which reflect the different empirical realisations of the temporal process under study. We explore criteria to inspect internal cluster composition and to detect deviant sequences, that is, cases characterised by rare patterns or outliers that might compromise cluster homogeneity. We also introduce tools to visualise and distinguish the features of regular and deviant cases. Our proposals offer a more accurate and granular description of the data structure, by identifying-besides the most typical types-peculiar sequences that might be interesting from a substantive and theoretical point of view. This analysis could be very useful in applications where-under the assumption of within homogeneity-clusters are used as outcome or explanatory variables in regressions. We demonstrate the added value of our proposal in a motivating application from life-course socio-demography, focusing on Italian women's employment trajectories and on their link with their mothers' participation in the labour market across geographical areas.

序列分析应用于不同领域,如人口学、社会学和政治学,以描述以分类状态序列表示的纵向过程。在许多应用中,序列被聚类以识别相关类型,这些类型反映了所研究的时间过程的不同经验现实。我们探讨了检查内部聚类组成和检测偏差序列的标准,即具有罕见模式或异常值的情况,这些情况可能会影响聚类的一致性。我们还介绍了可视化和区分正常与异常情况特征的工具。除了最典型的类型外,我们的建议还能识别从实质和理论角度来看可能很有趣的特殊序列,从而对数据结构进行更准确、更细化的描述。在应用中,根据内部同质性假设,聚类被用作回归中的结果或解释变量,这种分析可能非常有用。我们将在生命历程社会人口学的一个激励性应用中展示我们建议的附加价值,重点关注意大利妇女的就业轨迹及其与母亲跨地域参与劳动力市场的联系。

Does Abortion Liberalisation Accelerate Fertility Decline? A Worldwide Time-Series Analysis. 堕胎自由化会加速生育率下降吗?全球时间序列分析

Since WWII, the two most important global trends in family planning have been fertility decline and abortion liberalisation. But are they related? Specifically: Does abortion liberalisation affect changes in fertility rates? The demographic literature has yet to answer this important question and instead offers two opposing predictions. Some studies argue that liberalisation of this medical procedure reduces fertility rates. By contrast, others note that such legal reforms may merely have an average, negligible effect on fertility levels. We adjudicate between the two approaches by conducting, in our view, the most comprehensive global, quantitative analysis of the relationship between those legal reforms and changing fertility rates. The analysis relies on two-way fixed models and three different indicators of abortion policy liberalism created by independent research teams to estimate the relationship between abortion liberalisation and total fertility changes. The data cover 185 independent states between 1970 and 2019. Fertility rates are significantly related to average public education levels and alternative contraceptive use. Using multiple model specifications, however, abortion reforms do not have a robust association with the outcome.

自二战以来,生育率下降和堕胎自由化是全球计划生育的两大重要趋势。但它们之间有关联吗?具体来说是什么?堕胎自由化是否会影响生育率的变化?人口文献尚未回答这一重要问题,而是给出了两种截然相反的预测。一些研究认为,放开这一医疗程序会降低生育率。与此相反,另一些研究则指出,这种法律改革可能只会对生育水平产生平均的、可忽略不计的影响。在我们看来,我们对这些法律改革与生育率变化之间的关系进行了最全面的全球性定量分析,从而对这两种观点进行了评判。分析依赖于双向固定模型和由独立研究团队创建的三个不同的堕胎政策自由化指标,来估计堕胎自由化与总生育率变化之间的关系。数据涵盖 1970 年至 2019 年间的 185 个独立国家。生育率与平均公共教育水平和替代避孕药具的使用有明显关系。然而,使用多重模型规格,堕胎改革与结果并没有稳健的联系。本文的复制材料可在 https://figshare.com/s/5336a4422f47c8c39228 上找到。
