NIDI-KNAW is looking for a PhD Candidate for the Project: Explaining differences in union dissolution between municipalities: the role of compositional, contextual and cross-level effects

Job description

The PhD candidate will focus on explaining to what extent differences in union dissolution rates between Dutch neighborhoods and municipalities can be accounted for by compositional (individual characteristics such as religious involvement, household income and level of education), contextual (environment average religious involvement, household income and educational attainment) and cross-level effects (interactions between individual and contextual characteristics). The PhD candidate will perform analyses on linked survey and register data, available from Statistics Netherlands (CBS). Analysis will occur either on-site at CBS or at NIDI via Remote Access. Given the nested structure of the data, most analysis will be performed using multilevel modeling. The PhD candidate will provide various outputs: at least four publications in top peer-reviewed journals (demography, family studies and sociology journals will be targeted); presentations of articles at national and international sociological and demographic conferences; brief articles accessible to a wider audience; a dissertation based on the research articles.


The PhD position is funded by an NWO - open competition grant and will be supervised by prof. dr. A.C. Liefbroer (NIDI) and dr. M. Zoutewelle-Terovan (NIDI), and will be located at NIDI.

NIDI - the Netherlands Interdisciplinary Demographic Institute - is the national demographic institute of the Netherlands. NIDI was founded in 1970. NIDI became an institute of the Royal Netherlands Academy of Arts and Sciences (KNAW) in 2003 and is the only social science institute of the Academy. Since 2014 NIDI is also affiliated with the University of Groningen (UG).
Firmly rooted in science and society, NIDI strives for scientific excellence and draws its inspiration from the interplay of demographic and social issues.

Mission and Strategy

NIDI's mission is to conduct high-quality scientific research on population issues (our core activity) and to disseminate and enhance the use of demographic knowledge to stakeholders in academia, policy and society at large. We build and maintain a knowledge infrastructure for population issues to address the challenges that demographic developments pose to individuals and society. Population growth and decline, mobility and population distribution, population ageing and population diversity, life course dynamics, intergenerational relations, and health and longevity are but a few of the dimensions of the ever-changing landscape of population issues which make up the population challenge. Demographic research is needed to address this challenge and to study population trends and their impacts on economic development, the environment, social networks, social cohesion, health and care systems, retirement and social security issues, family life and wellbeing.

NIDI's aim is to create and share demographic knowledge and to enhance the use of this knowledge. Knowledge creation demands a creative combination of existing knowledge (theories), new empirical evidence (data) and methods of scientific enquiry. Knowing the facts ("what"), the determinants ("why"), the consequences ("so what") and the underlying mechanisms that link causes and observed trends ("how") is the best approach to take on the population challenge.

NIDI's vision is to further strengthen our position as a unique national and leading international institute for population studies. At the national level we aspire to play a vocal role in the scientific debate and societal discussions on population issues, while at the international level we want to secure our position as center of excellence in the context of the ongoing globalization of society.


Project description

In the Netherlands, every year more than 30,000 marriages end in divorce and 40,000 unmarried cohabitations end in separation. Union dissolution has huge economic and emotional consequences. Most studies on union dissolution focus on the role of individual characteristics, such as religious involvement, educational attainment and income. However, large differences between municipalities exist. In 2015, the divorce rate varied from 3 in Urk to 16 in Heerlen. This project aims to explain these differences, by disentangling compositional, contextual, and cross-level effects. A first explanation of differences in union dissolution rates between municipalities is that the percentage of people with protective individual characteristics (high income, high education, high religiosity) varies across municipalities. If the percentage of people with protective individual characteristics in a community is higher, the union dissolution rate is expected to be lower, just as a consequence of the composition of the population in terms of individual characteristics. A second explanation focusses on the contextual property of having a high percentage of people with protective individual characteristics around. This creates a protective context beneficial to all its inhabitants, irrespective of their individual characteristics. A third explanation stresses that the interaction between individual and context characteristics matters. Living in a protective environment reduces union dissolution rates for everyone, but less so for individuals with fewer protective characteristics, as the normative integration within the municipality is weaker for individuals whose characteristics differ from that of the majority. Linked register and survey data are used to test these hypotheses.
