About

This dashboard shows results from Wave 1 of the Berkeley Interpersonal Contact Study (BICS) in Spring 2020.

Caveats / underway:

  • the estimates have been weighted to improve sample representativeness. Weights are based on age, sex, race/ethnicity, household size, and urbanicity

  • see the ‘Contact definition’ tab for some important notes on how we define contacts

  • these results are from Wave 1; the dashboard previously showed results from the pilot Wave 0 (the previous dashboard is here

  • a comparison to Wave 0 results is coming soon; the instrument changed in some ways, and so a careful comparison will take some time

This project has been approved by the UC Berkeley IRB (Protocols 2020-03-13128 and 2020-04-13215). Initial support provided by a Berkeley Population Center pilot grant (NICHD P2CHD073964).
