From Concurrent to Push-To-Web Mixed-Mode: Experimental Design Change in the German Social Cohesion Panel

Research shows that concurrent and sequential self-administered mixed-mode designs both have advantages and disadvantages in terms of panel survey recruitment and maintenance. Since concurrent mixed-mode designs usually achieve higher initial response rates at lower bias than sequential mixed-mode designs, the former may be ideal for panel recruitment. However, concurrent designs producea high share ...

Immigration, Segregation, and Attitudes Toward Immigrants: A Longitudinal Multiscalar Analysis across Egohoods

Evidence on how proximity to ethnic outgroups shapes attitudes toward immigration remains inconclusive. We suggest this may be driven, in part, by the fact that studies rarely account for the role of residential segregation. We argue that how the minority-share in an environment affects majority-group attitudes will depend on how segregated groups are from one another. To explore this, we undertake ...

Do talk money – Reducing income nonresponse in surveys (with Katharina Allinger)

Item nonresponse is a common issue in surveys. We implement an experiment to reduce nonresponse to income questions in an international household survey, looking at four different countries. Survey respondents are asked to report their exact household income. We randomize those who refuse to answer into two groups. In a follow-up question, the control group is asked to choose their income from a...

Validating an Index of Selection Bias for Proportions in Non-probability Samples

Fast online surveys without sampling frames are becoming increasingly important in survey research. Their recruitment methods result in non-probability samples. As the mechanism of data generation is always unknown in such samples, the problem of non-ignorability arises making vgeneralisation of calculated statistics to the population of interest highly questionable. Sensitivity analyses provide a ...

State of DDI Cloud

As the DDI community continues to grow, an increasing number of repositories are providing their metadata in various DDI formats. However, the current landscape of DDI metadata standards usage is not well understood. Understanding this landscape is crucial as it helps identifying usage patterns, improve interoperability, and guide future developments. To address this research gap, we investigated the ...

How Many Brackets Should We Ask for to Derive Adequate Metric Information for Income and Wealth?

This paper investigates how the number of brackets and the choice of upper cutoffs in grouped data affect the metric approximation of income and wealth. The literature currently lacks a definition of what should be considered too few brackets or too-low cut-offs. Using German survey data, we show that more than six (eight) brackets and an upper cut-off at the 95th (97th) percentile are sufficient to ...

Introducing Open Data Format: A Platform-Independent, Non-Proprietary, Metadata-Enriched, Multilingual Data Format and its Implementation in R and Stata

This paper introduces the Open Data Format (ODF), a new, non-proprietary, multilingual, metadata enriched, and zip-compressed data format that meets the FAIR Guiding Principles for scientific data management and stewardship. The data format is specified as a CSV file with the raw data and an XML file containing the metadata both compressed into a zip file with the .zip extension. Data files can ...

Refugees Send Remittances Abroad Less Often than Other Migrants

Remittances sent by refugees to their home countries has been a hotly debated policy topic in Germany over the past years and has led to the introduction of a payment card for asylum applicants. This Weekly Report investigates how the share of people living in Germany who send remittances abroad has changed over time according to their migration background (with or without a refugee background) and ...

Geflüchtete senden seltener Geld ins Ausland als andere Migrant*innen

Über Geldüberweisungen von Geflüchteten in ihre Heimat wurde in den vergangenen Jahren in Deutschland politisch scharf debattiert, was zur Einführung einer Bezahlkarte für Asylbewerber*innen führte. Die vorliegende Studie untersucht, wie sich der Anteil der in Deutschland lebenden Personen, die Geld ins Ausland überweisen, im Laufe der Zeit je nach Migrationshintergrund – mit oder ohne Fluchthintergrund ...
