  • Estimating annual rates of homelessness (by James O'Donnell)

    • Abstract: BACKGROUND
      Homelessness is an important though exceedingly difficult phenomenon to measure and understand. The most common sources of data measure homelessness only on a given night or set of consecutive nights, contact with homelessness service providers, or past homeless episodes. We therefore lack an understanding of the wider impact and nature of homelessness in society.
      OBJECTIVE
      I set out to estimate the number of people who experience homelessness in a one year period by duration and type of homelessness.
      METHODS
      A microsimulation model is used to recreate homeless episodes and impute those missed in common data sources. Model parameters are estimated using a combination of retrospective and longitudinal survey data from Australia. Administrative data from homelessness service providers are used to validate the estimates.
      RESULTS
      According to the results, 3.4 times as many people experienced homelessness in Australia in the 2013–2014 financial year than would have been counted on an average night. Almost one-third (32%) of episodes last for less than one month and the large majority involve ‘couch surfing’ or ‘doubling up’ with relatives or friends.
      CONCLUSIONS
      Homelessness and housing deprivation is more prevalent though more diverse and episodic than typically measured, affecting a large cross-section of the population and likely embedded within the dynamics of poverty and deprivation.

  • The formal demography of kinship II: Multistate models, parity, and
           sibship (by Hal Caswell)

    • Abstract: BACKGROUND
      Recent kinship models focus on the age structures of kin as a function of the age of the focal individual. However, variables in addition to age have important impacts. Generalizing age-specific models to multistate models including other variables is an important and hitherto unsolved problem.
      OBJECTIVE
      The aim is to develop a multistate kinship model, classifying individuals jointly by age and other criteria (generically, “stages”).
      METHODS
      The vec-permutation method is used to create multistate projection matrices including age- and stage-dependent survival, fertility, and transitions. These matrices operate on block-structured population vectors that describe the age×stage structure of each kind of kin, at each age of a focal individual.
      RESULTS
      The new matrix formulation is directly comparable to, and greatly extends, the recent age-classified kinship model of Caswell (2019a). As an application, a model is derived including age and parity. It provides, for all types of kin, the joint age×parity structure, the marginal age and parity structures, and the (normalized) parity distributions, at every age of the focal individual. The age×parity distributions provide the distributions of sibship sizes of kin. As an example, the model is applied to Slovakia (1960–2014). The results show a dramatic shift in the parity distribution as the frequency of low-parity kin increased and that of high-parity kin decreased.

  • Mobile phones, digital inequality, and fertility: Longitudinal evidence
           from Malawi (by Francesco Billari, Valentina Rotondi, Jenny Trinitapoli)

    • Abstract: BACKGROUND
      In this paper, we introduce the digital revolution as a potential ingredient of sub-Saharan Africa’s fertility transition.
      OBJECTIVE
      We focus on the relationship between mobile phone ownership and childbearing in southern Malawi, showing that mobile phone acquisition is associated with reductions in ideal family size and lower overall parity among phone-owning women compared to their phone-less counterparts.
      METHODS
      We use nine waves of data from the Tsogolo la Thanzi (TLT) longitudinal study conducted in Balaka, Malawi, between 2009 and 2015.
      RESULTS
      Fixed-effects panel data models shows that mobile phone ownership is associated with smaller ideal family size and lower parity during the study period. Cox proportional hazard models suggest that mobile phones are not fundamentally associated with the timing of women’s first steps in family formation but rather with fertility trajectories on a longer time-horizon through child spacing. Furthermore, complementary cross-sectional analyses from a later survey round suggest that mobile phone ownership is associated with fertility through role modeling, preference change, and access to information.
      CONCLUSIONS
      Mobile phone ownership is associated with fertility via role modeling, preference change, and access to information rather than through substitution effects.

  • Greater mortality variability in the United States in comparison with peer
           countries (by Richard G. Rogers, Robert A. Hummer, Justin M. Vinneau,
           Elizabeth M. Lawrence)

    • Abstract: BACKGROUND
      Over the past several decades, US mortality declines have lagged behind other high-income countries. However, scant attention has been devoted to how US mortality variability compares with other countries.
      OBJECTIVE
      We examine trends in mortality and mortality variability in the US and 16 peer countries from 1980 through 2016.
      METHODS
      We employ the Human Mortality Database and demographic techniques – with a focus on patterns in the interquartile (IQR), interdecile (IDR), and intercentile (ICR) ranges of survivorship – to better understand US mortality and mortality variability trends in comparative perspective.
      RESULTS
      Compared to other high-income countries, the US: (1) mortality ranking has slipped for nearly all age groups; (2) is losing its old age mortality advantage; (3) has seen growth in relative age-specific mortality gaps from infancy through midlife; and (4) exhibits greater concentrations of deaths from infancy through adulthood, resulting in much greater mortality variability.
      CONCLUSIONS
      We contribute to calls for renewed attention to the relatively low and lagging US life expectancy. The ICR draws particular attention to the comparatively high US early and midlife mortality.

  • The power of the government: China's Family Planning Leading Group and the
           fertility decline of the 1970s (by Yi Chen, Yingfei Huang)

    • Abstract: BACKGROUND
      China introduced its world-famous One-Child Policy in 1979. However, its fertility appears to have declined even faster in the early 1970s than it did after 1979. The fertility rate declined by three children, from 5.7 in 1969 to 2.7 in 1978.
      OBJECTIVE
      What accounts for such a rapid decline in fertility rate during the 1970s' In this study, we highlight the importance of the Family Planning Leading Group (FPLG) in understanding China’s fertility decline since the early 1970s.
      METHODS
      From 1969 to 1975, provinces gradually established agencies of the FPLG to implement family planning policies. We construct a difference-in-difference (DID) model to estimate the policy effect by exploiting the provincial variation in establishment years. We also develop a measure of policy exposure based on the province and the mother’s birth cohort that is applicable to many publicly available household-level data.
      CONCLUSIONS
      Our DID model explains about half of China’s total fertility rate decline from 5.7 in 1969 to 2.7 in 1978. Additionally, despite its simple construction, our proposed policy measure aptly explains China’s rapid decline in family sizes.

  • Young women's joint relationship, sex, and contraceptive trajectories:
           Evidence from the United States (by Bridget Brew, Abigail Weitzman, Kelly
           Musick, Yasamin Kusunoki)

    • Abstract: OBJECTIVE
      We identify common patterns of joint relationship, sex, and contraceptive trajectories in young adulthood and assess how selection into these trajectories differs across socioeconomic and demographic groups and varies with earlier sexual and reproductive experiences and attitudes.
      METHODS
      We draw on a weekly panel of 581 young adult women in the United States that includes granular data on sexual and contraceptive behaviors. We use sequence analysis to describe joint relationship, sex, and contraceptive trajectories over the course of a year and multinomial logistic regression to examine how these trajectories are associated with socioeconomic disadvantage and minority racial status.
      RESULTS
      We identify six trajectories characterized by differences in relationship stability, sexual regularity, and contraceptive efficacy. Many women report no romantic relationships over the year. Among those who do, instability in relationships, sex, and contraception is common. Less advantaged women are more likely to be on trajectories marked by frequent relationship transitions, coresidence, and less effective contraception. These socioeconomic differences are largely explained by earlier experiences and attitudes. Black women are the most likely to be on a trajectory characterized by simultaneous relationship, sex, and contraceptive instability, and this holds net of earlier experiences and attitudes.

  • Ready for parenthood' Dual earners' relative labour market positions
           and entry into parenthood in Belgium (by Leen Marynissen, Karel Neels,
           Jonas Wood, Sarah Van de Velde)

    • Abstract: BACKGROUND
      Rising symmetry in public gender roles as a result of women’s rising educational and labour market participation could make both partners’ labour market positions equally relevant with respect to family formation. It is, however, unclear whether and to what extent this evolution has materialised. To date, few studies have examined couple dynamics in the employment–fertility link, and especially the gendered nature of this link remains understudied.
      OBJECTIVE
      This study examines the effect of dual earners’ relative income, job stability, time availability, and employment-sector-specific flexibility in terms of work regimes on the transition to parenthood in Belgium.
      METHODS
      Using longitudinal microdata from the Belgian Administrative Socio-Demographic Panel, we estimate discrete-time hazard models of conception leading to a first birth.
      RESULTS
      Controlling for employment characteristics at the household level, we find higher first birth hazards when the female partner has higher time availability or access to flexible work regimes, suggesting a persistent gendered precondition to parenthood. By contrast, the gender distribution of income does not affect the transition to parenthood.

  • Calloused hands, shorter life' Occupation and older-age survival in
           Mexico (by Hiram Beltrán-Sánchez, Noreen Goldman, Anne Pebley, Josefina
           Flores Morales)

    • Abstract: BACKGROUND
      Inequalities in mortality are often attributed to socioeconomic differences in education level, income, and wealth. Low socioeconomic status (SES) is generally related to worse health and survival across the life course. Yet, disadvantaged people are also more likely to hold jobs requiring heavy physical labor, repetitive movement, ergonomic strain, and safety hazards.
      OBJECTIVE
      We examine the link between primary lifetime occupation, together with education and net worth, on survival among older adults in Mexico.
      METHODS
      We use data from four waves (2001, 2003, 2012, and 2015) of the Mexican Health and Aging Study (MHAS). We estimate age-specific mortality rates for ages 50 and over using a hazards model based on a two-parameter Gompertz function.
      RESULTS
      Primary lifetime occupations have a stronger association with survival for women than men. Women with higher socioeconomic status have significantly lower mortality rates than lower status women, whether SES is assessed in terms of schooling, wealth, or occupation. Occupational categories are not jointly related to survival among men, even without controls for education and wealth. There are significant survival differences by wealth among men, but no disparities in mortality by education.
      CONCLUSIONS
      Consistent with recent studies of the Mexican population, we fail to find the expected gradient in the association between some measures of SES and better survival among men.

  • Fertility patterns of migrants from low-fertility countries in Norway (by
           Marianne Tønnessen, Eleonora Mussino)

    • Abstract: BACKGROUND
      Most research on migrant fertility focuses on immigrants from high-fertility countries who have moved to countries with lower fertility. Little is known about the fertility of immigrant women from countries where fertility is lower than in the destination country.
      OBJECTIVE
      This study investigates fertility rates among women from low-fertility countries who have moved to a country where fertility is comparatively higher (Norway).
      METHODS
      Register data on immigrant women from Poland, Lithuania, and Germany are used to calculate total fertility rates by duration of stay and to explore differences between family migrants and women who migrate for other reasons, between women of different ages at arrival, and between those who emigrated again and those who remained in Norway.
      RESULTS
      Among immigrants from low-fertility countries, total fertility rates are elevated in the first years after migration. This is particularly true for women from Poland and Lithuania, who often arrive as family migrants and at peak fertility age (25 to 34 years).

  • The emergence of birth limitation as a new stage in the fertility
           transition in sub-Saharan Africa (by Mathias Lerch, Thomas Spoorenberg)

    • Abstract: BACKGROUND
      The fertility transition started later in sub-Saharan Africa than in other regions of the world. Moreover, the average number of children per woman declined more slowly there, owing to a distinct mechanism of fertility reduction. It has been argued that the fertility decline in sub-Saharan Africa proceeded through an increase in birth intervals rather than by a limitation of the number of births.
      OBJECTIVE
      We analyze the fertility transitions in 29 countries to determine which mechanism women resort to in order to reduce their number of children.
      METHODS
      Using multiple sample surveys, we estimate and cross-validate trends in parity progression ratios and birth intervals. We identify sub-regional regularities and vanguard trends in the interplay between the dynamics of the lengthening of birth intervals and birth limitation over the period 1962‒2012.
      RESULTS
      While initial fertility declines were driven by a lengthening of birth intervals at all parities, we observe a recent onset of birth limitation in regions and countries that are most advanced in the fertility transition.
      CONCLUSIONS
      The experience of sub-Saharan Africa shows that if all parities contribute to the fertility transition from the outset, the main drivers of the fertility decline switch from a lengthening of birth intervals to a limitation of family size when the average fertility reaches about five children per woman.

  • Entrance into parenthood at the onset of low fertility in Ukraine: The
           role of family relationships and perceived security (by Yuliya Hilevych)

    • Abstract: BACKGROUND
      In post-Soviet countries, low fertility has been achieved through postponement of second birth, while entrance into parenthood still takes place relatively early in life and within marriage. Studies suggest that grandparental support with childcare drives this reproductive behaviour. However, we still know little about the exact way in which decisions about first parenthood are shaped by family relationships, especially with respect to the expected and actual support they exert.
      OBJECTIVE
      This paper explores how family relationships – spousal and intergenerational – influenced decisions to enter parenthood in Ukraine between 1950 and 1975, when fertility there declined below the replacement level for the first time.
      METHODS
      A total of 66 qualitative life-history interviews were conducted with women and men from the Ukrainian cities of Lviv (west) and Kharkiv (east); age-specific fertility rates and the total fertility rate in 1960 were measured for the two provinces.
      RESULTS
      The informants shared their notions about the right timing for first parenthood, which parents(-in-law) helped them to navigate. This guidance, in turn, created expectations about the provision of help with childcare, which facilitated a feeling of security when entering parenthood in economically insecure circumstances, which are defined as perceived security. The actual provision of childcare by parents(-in-law), however, was contingent on spousal relationships, which differed between the two cities.
