In this project, we have investigated whether gender determines field of publication. Our analysis was based on all papers published in “Demography” which is the flagship journal of the Population of America Association (PAA) and currently celebrates its 50th anniversary. We scrutinized all issues of „Demography” and compiled information on title, topic as well as gender of all authors. This Technical Report describes how we set up the resulting database. The Report is accompanied by the respective database (in STATA-format, version 13.0).

More specifically, we focus on the transition to the second child and compare the behavior of respondents in ongoing partnerships (couples who are still partnered with the mother/father of their first child) with those who have experienced family dissolution after the first birth. The investigation reveals strong gender differences in postseparation fertility behavior. We also find large regional differences. Eastern Germans had much lower second birth rates than western Germans. However, they were more prone than western Germans to have their second child with a parent who was not the father or the mother of their firstborn child. This result is in line with descriptive findings on the diversity of family structures in eastern Germany.

With its large sample size, the dataset also offers the opportunity to investigate childbearing among population subgroups, such as particular migrant groups. Because birth histories are not surveyed in the Mikrozensus, scholars have frequently employed the Own-Children Method (OCM) to generate fertility schedules from this data. The OCM draws on information on the number and ages of the co-residential children in order to estimate the fertility schedule of women. It is clear that this method leads to an underestimation of fertility, because children do not necessarily live with their biological mother. It is also clear that the bias is stronger for older women, because children may have left parental home. In the past, it was not possible to assess the bias. With the Mikrozensus 2008, we are able to validate the OCM by relying on respondent’s own report on the total number of children. We furthermore examine whether the OCM leads to worse estimates for migrants and non-migrants. The results show that the OCM provides reasonable fertility estimates for women in western Germany up to age 40, irrespective of migrant background. For eastern Germany, there is a stronger bias at later ages than in western Germany. This relates to the early age at childbirth in this region and the more diverse family structures.

How different survey methods affect respondents’ reports of partnership status at first birth N2 - This paper examines the reliability of biographical information gathered retrospectively. It draws on data from the German Family Panel (pairfam), which collected information on the partnership status at first birth using two different methods. The first method is based on data on partnership and fertility histories collected retrospectively. The second method uses data gathered through the use of a “landmark question” on the respondents’ partnership status when their first children were born. We find that in almost 20 percent of the cases, the information collected using the first method did not correspond with the information collected using the second method. Partnership dissolution and “turbulence” in the partnership biography are strong predictors for discrepancies in the information gathered through the two different survey methods. We conclude by drawing attention to the limitations of the retrospective collection of partnership histories at a time when divorce and separation rates are increasing.

The Harmonized Histories is a comparative database of rich reproductive and union histories from surveys conducted in a number of countries in Europe. Given that birth and union data has been collected in a number of ways in different surveys, it has been very difficult to conduct cross-national analyses of recent union and fertility behavior over time. A team of researchers called the Nonmarital Childbearing Network has cleaned and standardized the surveys according to guidelines set out in this manual. Currently, the database includes data from the Generations and Gender Surveys (GGSs) in Italy, Germany, France, Bulgaria, Hungary, Romania, and Russia; the 2003 Dutch Fertility and Family Survey; and the British Household Panel Survey.

Sofern aus einer Beziehung gemeinsame Kinder hervorgegangen sind, impliziert eine Trennung zwar das Ende der Partnerschaft, jedoch nicht das Ende der Elternschaft. Sowohl auf gesellschaftlicher als auch auf individueller Ebene besteht, mit Ausnahme von Sondersituationen, mittlerweile die explizite Erwartung, dass Eltern nach einer Trennung in ökonomischer und sozialer Hinsicht weiterhin gemeinsam Verantwortung für ihre Kinder wahrnehmen. In der gesetzlichen Grundlage wird allerdings weiterhin davon ausgegangen, dass Kinder nach der Trennung bei nur einem Elternteil leben. Für andere Modelle existieren bisher keine oder nur unzureichende Regelungen. Die ökonomischen, sozialen und psychischen Folgen einer Trennung oder Scheidung können nach Geschlecht, sozialer Position und Alter variieren und damit soziale Ungleichheit hervorrufen oder verstärken. Neue Partnerschaften bzw. sogenannte Fortsetzungsfamilien beeinflussen das Leben der betroffenen Erwachsenen und Kinder zusätzlich. Bislang existieren über die Verbreitung und Lebensumstände von Nachtrennungsfamilien in Deutschland nur rudimentäre sozialwissenschaftliche Befunde. Die vorliegende Broschüre stellt einen ersten Versuch dar, bislang vorliegende sozialwissenschaftliche Befunde zur Lebenswirklichkeit von Nachtrennungsfamilien in Deutschland allgemeinverständlich in knapper Form zu bilanzieren. Folgende thematische Schwerpunkte werden behandelt: 1) Allgemeine Trends und rechtliche Rahmenbedingungen, 2) Elternschaft und Partnerschaft nach Trennung und Scheidung, 3) Wohlbefinden und Lebenszufriedenheit nach Trennung und Scheidung sowie 4) Finanzielle Folgen von Trennung und Scheidung. Diese Aspekte werden aus unterschiedlichen Perspektiven beleuchtet und zugrundeliegende empirische Analysen decken ein breites Spektrum der derzeit verfügbaren Datenquellen ab.

However, regional identifiers are sensitive information and including them in a scientific-use-file of a survey may violate data protection regulations.

The analyses focus on women and men born around 1970 who are followed until age 41. We show that multipartner fertility is more common in Finland than in Germany. However, there are large East-West differences within Germany. East Germans are less likely to have a second or third child than West Germans, but those East Germans who progress to a higher order birth more often have this child with a new partner. We also find some gender differences in behaviour. Men display lower transition rates than women of having a second child with a new partner. We also examined individual-level factors associated with multipartner fertility. Having a first child at an early age is strongly and positively associated with multipartner fertility. No consistent relationship between education and multipartner fertility was found for Germany. In Finland, however, low education is associated with elevated risks of having children with different partners.

Since the 1970s, several European countries have experienced both high rates of union dissolution and high unemployment rates. This article uses the experience of five European countries before the recent economic crisis to explore the relationship between both individual and aggregate unemployment and union dissolution risk. Using rich longitudinal data from Belgium, Finland, France, Germany, and Italy, discrete-time models show that male partner’s unemployment increases the risk of union dissolution in all countries. Female partner’s unemployment is associated to more varied effects and is only significant in countries where it is standard practice to be in paid employment. The effect is always of lower magnitude than the male partner's unemployment. Interestingly, there is no association between unemployment and union dissolution at the macro level for men. In France and Belgium, we find that individual unemployment during a recession lowers divorce risk for women, while it increases them in Italy. Findings are interpreted in light of the different ways that individual unemployment may be perceived during recession.
