Model-based estimates of social contact by study wave and characteristics. We fit generalized estimating equations with robust standard errors to estimate how predictors of the total number of non-household contacts varied across the three BACK study waves. Plots estimate the expected count of non-household contacts with models interacting study wave with A age B whether household identifies as Hispanic C race/ethnicity D combined household income and E indicators of ability of adults to work from home during COVID-19 physical distancing restrictions. All models adjust for age, race/ethnicity, household count, and household income
