In this population-based study we analyze immigrant advantages in birthweight decomposing differences between infants born to immigrant mothers from specific origins. Method Using publicly available data from Spanish Vital Statistics for the period 2007–2017, differential birthweights among several groups of immigrants were estimated with an ordinary least squares regression. The Oaxaca–Blinder regression-based decomposition method was then applied to identify the extent to which differences in birthweight between groups corresponded to compositional disparities or to other factors. Results Our analysis of singleton live births to migrant mothers in Spain between 2007 and 2017 (N = 542,137) confirmed the healthy immigrant paradox for certain immigrant populations settled in Spain. Compared with infants born to mothers from high-income countries, the adju...

Los nuevos datos del INE sobre mortalidad por edad y nivel de instrucción para hombres y mujeres permiten medir esas diferencias como probabilidades de muerte y esperanzas de vida en la España de 2012. La distancia es más que notable: un hombre de 30 años y nivel de instrucción alto puede esperar vivir de media tres años y ocho meses más que un coetáneo de nivel educativo elemental. Esa desigualdad educativa ante la muerte es mayor entre los hombres que entre las mujeres; además, la tradicional diferencia ante la mortalidad por razón de género tiende a disminuir cuanto mayor es el nivel educativo. Aunque hay que ser prudentes a la hora de establecer causalidades, todo apunta a que la educación, con sus consiguientes diferenciales en condiciones laborales, económicas y culturales, es un elemento determinante de las desigualdades ante la muerte y la longevidad.

We quantified the effects of SES on birthweight disparities between native and immigrant mothers in Spain. We obtained birth and SES data from the 2011 census and administrative registers for years 2011–2015. The associations between origin, statuses, and the likelihood of low birthweight were estimated using logistic regressions. Fairlie’s nonlinear extension of the Oaxaca–Blinder decomposition method was applied to identify the extent to which the differences in birthweight between groups corresponded to socio-economic composition or to rates. Our results showed that African and Latin American mothers exhibited advantage in the perinatal outcomes over native mothers [odds ratio (OR) 0.75; 95% confidence interval (CI) 0.63–0.90 and OR 0.73; 95% CI 0.65–0.82, respectively]. Decomposition analyses revealed that such advantage was not affected by the ...

Drawing on data from the Labour Force Survey we estimate an entropy-based segregation index in order to assess the extent to which the unevenness of the distribution of natives and immigrants within social classes has contributed to the overall demographic composition of social class structure. Our results reveal that in the period of economic expansion the segregation of the class structure increased as a result of the concentration of immigrant population in specific classes. In contrast, during the economic crisis this process has been reversed: the uneven class distribution between natives and immigrants has levelled out and segregation among natives has decreased.

Different factors behind the residential choices of elderly women are estimated by means of logistic regression. Decomposition models are used to assess the extent to which observed differences between countries correspond to specific population compositions or to other factors. Although the importance of all independent variables for living alone is shown to be strong and statistically significant, persistent intercountry disparities in behaviour linked to levels of familism and development remain. Population composition explains only a small part of the observed differences in living alone. Economic development provides an important underlying explanation for the incidence of living alone among women, but many specific differences can also be explained by societal characteristics such as family systems and available policy options. KEYWORDS development, family systems, living alone, management of aging 1 | INTRODUCTION The increasing incidence of solo living among older persons in the developed world is often seen as the result of modernisation and how this changes the traditional dependence on the family, substituting it wherever possible with residential independence and institutional options for the overall management of aging (Gaymu et al., 2006;

With microdata coming from census (Spain) and linked administrative registers (Sweden), logistic regression techniques, including a nonlinear regression–based decomposition of differences between, are used to estimate the weight of different factors behind the residential choices of elderly women. Theoretical expectations are validated. Levels of living alone are associated with age, childlessness, marital status, and education in both populations. Population characteristics (compositions effects) explain only a small part of the differences in living alone between both countries, while behaviors (rate effects) account for the larger part of the variation. Therefore, among elderly women proximate determinants of living arrangements produce differ...

Spain also shows these basic trends, but the fit is not identical to that of other countries, with differences affecting the timing of trend changes and also the levels of childlessness observed in the final part of the period. This paper focuses on Spanish women born 1920 and 1969 and explores the factors characterizing traditional/old childlessness and how these differ from those holding more recently. Using microdata from Spanish Census of 2011, our approach makes use of logistic regression and regression-based decomposition techniques. Change over time, as measured by inter-cohort variations, reveals strikingly different patterns of behaviour characterized by a reversal of the traditional association of childlessness with marital status and educational attainment that takes place in a period of intense and pervasive social change.

The expected implication was fertility decline and postponement, whereas in fact the opposite occurred. We analyse trends in the quantum of cohort fertility among the baby boom generations in 15 countries and how these relate to women's education. Over the 1901-45 cohorts, the proportion of parents with exactly two children rose steadily and homogeneity in family sizes increased. Progression to a third child and beyond declined in all the countries, continuing the ongoing trends of the fertility transition. In countries with a baby boom, and especially among women with post-primary education, this was compensated for by decreasing childlessness and increasing progression to a second child. These changes, linked to earlier stages of the fertility transition, laid the foundations for later fertility patterns associated with the gender revolution.

Using data from the Economically Active Population Survey and life tables, we estimate the expected time in work, unemployment, retirement, and other types of economic inactivity during the economic boom-and-bust cycle. Differences in expected years of life spent in different employment statuses are decomposed into effects of mortality and employment behavior. Our results show that men's working life expectancy is much more exposed to economic fluctuations. The impact of the ebbs and flows of the business cycle among women is mitigated by the long-term female trend of growing participation in the labor market associated with the increasing educational attainment of women. In addition, the improvement in mortality only partially contributes to gains in time spent in each status, while the main effects correspond to changes in labor market participat...

The Catholic Church was a key political actor during the Franco regime in Spain and communist rule in Poland. However, the nature of its political involvement in each case was quite different: while in Spain the Catholic Church legitimized the Franco regime, in Poland it was one of the main actors opposing communist rule. The authors use data from the Polish General Social Survey covering 1991–2008 and several surveys carried out by the Spanish Centre for Sociological Studies (CIS) between 1975 and 1995. Results confirm that the political involvement of the Catholic Church had different impacts on subsequent religious practice in each country. In Spain secularization was especially intense during the political transition in the late 1970s, while in Poland after the 1990s there was only a moderate shift toward secularization.

Based on microdata from the 2011 Spanish population census, logistic regression techniques are used to assess the impact of fertility on living alone among elderly women net the effect of age, marital status, educational attainment, and other standard population controls. Our results show a clear relationship between completed fertility and living alone. Childlessness is strongly associated with living alone, while having offspring acts as a powerful buffer against living alone, particularly in larger families. A relevant conclusion of this study is that a growing deficit of family resources available for the elderly women will take place in those societies where low fertility and high rates of childlessness have prevailed in recent decades, leading to substantial growth in the number of childless elderly women and in the incidence of living alone during later life.
