Tracking Mask Mandates
During summer 2020, I led two research labs that collected a comprehensive, county-specific database of local mask mandates. To advance scientific research on the importance, phased roll out, and downstream consequences of mask mandates, we have made this data publicly available and free to download. We ask anyone using the data to cite our working paper and acknowledge the source of the data.
The latest data can be retrieved at this link: current link (04/05/2021). _edate columns are generated using Stata's date function, which is centered at `01jan1960'. We thank Billy Ferguson for pointing out a quirk in some of the rows. This has been resolved with a new file upload.
Additional details about the data are available in this working paper: Tracking Mask Mandates during the COVID-19 Pandemic. With Geet Chawla, Luke Chen, Anthony Farmer, IPAL Lab, DPSS Lab. If you use the data, please cite this paper and consider reviewing our other COVID-19 projects where we use this and related data.
