## Eligibility & scope

Open to researchers at German institutions (DFG funding rules apply; host institution must have implemented DFG Code of Conduct).

## Summary

The DFG Infrastructure Priority Programme "New Data Spaces for the Social Sciences" (SPP 2431) funds methodological research to enhance longitudinal panel surveys, with a focus on data integration, respondent-driven designs, instrument validity, and multimodal data acquisition. The second funding period awards three-year grants (2027-2030) to researchers at German institutions developing innovations in social science data infrastructure. This is a one-off call designed to strengthen the technical and methodological foundations of panel research in Germany.

## Who should apply

- Researchers at German universities and research institutions with DFG Code of Conduct implementation
- Social scientists working on panel survey design and data architecture
- Teams with expertise in data integration, linkage, or multimodal acquisition methods
- Applicants addressing one of four priority areas: data integration/linkage, respondent-driven designs, instrument validity, or multimodal data for panel surveys

## Key dates

- Project outline due 10 April 2026; preparatory workshop 8 May 2026; elan portal registration by 9 September 2026
- Full proposal deadline 16 September 2026
- Decisions expected March 2027; funding period 2027-2030 (three years)

## Tips for applicants

- This is a one-off call, not recurring, if you miss the September deadline, the programme does not reopen.
- The preparatory workshop in May is optional but valuable for refining your project outline; attendance signals engagement with the priority areas.
- Frame your proposal around one of the four named research areas (data integration, respondent-driven designs, instrument validity, multimodal data); generic panel-survey improvements will not compete.
