In this repository, we report the aggregated contact data that underlie the analyses reported in the paper entitled "The differential impact of physical distancing strategies on social contacts relevant for the spread of SARS-CoV-2: Evidence from a cross-national online survey, March – April 2020" and published on *BMJ Open*.
Data are provided as weighted averages of daily contact numbers by threshold, country, calendar week, and setting, both overall and stratified by region of residence, age group and sex.
