Change of mode, change of bias? An analysis of differences in migrant survey participation following mode changes in the Austrian Social Survey (SSA) and the Austrian segment of the European Social Survey (ESS)
Migrants are a diverse and potentially disadvantaged minority group which makes them hard-to-reach and hard-to-survey. As migrant research often relies on general population survey studies, it is important to understand the potential consequences of these surveys shifting from traditional face-to-face to mixed-mode interviews for the composition of migrant samples. By comparing the Austrian segment of [...]

Comparing the ‘Most Important Problem’ Measure of Issue Salience and Google Trends: Methodological Lessons from the Field
Survey-based measures such as the ‘most important political problem’ (MIP) question are a central tool for studying public issue salience, but they are costly to field frequently and provide only temporally sparse snapshots. Digital trace data, e.g. Google Trends, are therefore increasingly discussed as a low-cost, high-frequency alternative or complement. However, systematic evidence on how [...]

Comparing panel retention among Ukrainian and other refugees in a German probability-based panel: Evidence from a decomposition analysis
Despite the rise in global refugee migration, probability panels surveying refugees remain rare. The German IAB-BAMF-SOEP Survey of Refugees, conducted annually since 2016, provides valuable panel data for research. In 2023, following Russia’s invasion of Ukraine, a sample of Ukrainian refugees was added, along with a refreshment sample of refugees from other countries. This paper [...]

Can we understand persons’ postponement in web surveys? Results from communication experiments in the Netherlands.
At Statistics Netherlands, we experienced a decline in response rates on social surveys, similar to other National Statistical Institutes (NSIs). In this paper we reflect on the general research question that investigates the effect of different types of procrastination on response behavior within the Dutch Labor Force Survey (LFS). The hypothesis is that procrastinating, not [...]
