The Robert Koch Institute regularly conducts health interview surveys of the study "German Health Update" (GEDA) as part of its nationwide health monitoring.

GEDA 2023

The GEDA 2023 telephone survey took place from January 2023 to February 2024. The survey was structured into a core questionnaire and up to four questionnaire modules. Each module can be analysed on its own.

Every month, about 1000 people per module aged 18 and over were interviewed by telephone (mobile and landline connections).
