Longitudinal surveys play a central role in social science research and policy advice but increasing demands for timely data pose substantial challenges for managing time, resources, and data quality across survey waves. While the Survey Life Cycle (SLC) provides a well established framework for organizing survey production, it is primarily geared toward single wave studies and offers limited guidance ...

Several research groups have developed algorithmic tools to optimize refugee-location matching, with the overall aim of improving refugees’ integration outcomes. These tools are used in a highly sensitive context and thus their design, ...

Motivated by research on gender identity norms and the distribution of the woman’s share in a couple’s total labor income, we consider additive regression models for densities as responses with scalar covariates. To preserve nonnegativity and integration to one under vector space operations, we formulate the model for densities in a Bayes Hilbert space, which allows to not only consider continuous ...

Mit der Aktivrente plant die neue Regierungskoalition eine kräftige steuerliche Begünstigung von erwerbstätigen Rentner*innen. Diese sollen bis zu 2000 Euro im Monat steuerfrei hinzuverdienen können. Die Regierung erhofft sich, damit mehr Rentner*innen zum Weiterarbeiten zu motivieren und so dem Fachkräftemangel entgegenzuwirken. Mikrosimulationsanalysen auf Basis des Sozio-oekonomischen Panels (SOEP) ...

Vor dem Hintergrund der demografischen Alterung in Städten gewinnt die Betrachtung der Lebensbedingungen Älterer an Bedeutung. Mittels kommunalstatistischer Daten der Innerstädtischen Raumbeobachtung und Geodaten wird untersucht, wie viele Einrichtungen der Daseinsvorsorge es in Stadtteilen deutscher Großstädte gibt. Es stehen Stadtteile mit einem hohen Anteil von Personen ab 65 Jahren im Fokus, um ...

Methods: Multiple data sweeps were utilised from the Millennium Cohort Study, a nationally representative longitudinal study of children born in the UK in 2000-2002. Mental health ...
