We present here data on crop insurance adoption by farmers in France. Data were collected via an original questionnaire survey available online from February 2021 to October 2021. We collected 465 responses of which 288 were complete. The survey contained 57 questions divided into 5 parts: 1/ Farm characteristics; 2/ Crop insurance behaviour and preferences; 3/ Determinants of crop insurance adoption; 4/ Expectation for the future; 5/ Socioeconomic characteristics. We use different methodologies (binary or multiple choices questions, experimental tests, Likert scales, self-ranking, etc.) in order to assess farmers preferences for crop insurance adoption. This data set was used for the first time in the paper: Koenig, R. and Brunette M. 2023. “Subjective barriers and determinants to crop insurance adoption” WP BETA 2023-25.
