Race and age patterns of social contacts by location. The gray region represents the confidence interval for the difference between the age-specific means for Non-Hispanic Black and Non-Hispanic White respondents. The Non-Hispanic Black and Non-Hispanic White age patterns are statistically different for age groups where the Black line does not cross the confidence intervals. Non-Hispanic Blacks had the shortest duration of contact, with a substantial and persistent gap between them and Non-Hispanic Whites/Hispanics at all age groups. The latter is driven by differences in duration of contacts in the home. In this figure duration of contacts in the home/yard is not restricted to interactions with household members
