The broodfonds data was collected with a survey distributed among all 10230 members of the 230 broodfonds groups that were established before 1 Feb 2017. The data collection period ran from May 8, 2017 until June 14, 2017. Within this period, 5192 respondents (59.7%) filled in the questionnaire. This questionnaire contained questions about motivation for membership, personal characteristics, health and sickness, and social relations. All chairpersons of the 230 broodfonds group were invited to fill in a second questionnaire, which contained questions about the rules of their broodfonds group, the social relations within their group, the attendence at meetings, and sickness history of members of their broodfonds. This survey was completed for 196 of 230 groups (85.2%). The resulting dataset is a multilevel dataset with group-level and member-level properties.
The survey design and data collection has been executed in collaboration with the BroodfondsMakers. Given the sensitivity of some questions (e.g., on sickness history), data access is restricted.
