Fig. S2.

Temporal trend in median age of COVID-19 tests and median age of positive COVID-19 tests by race-ethnicity, gender, and urban-rural status. Fig. S2 extends the results of Fig. 3 by showing temporal trends in the median age of people receiving COVID-19 tests and positive COVID-19 tests by race-ethnicity stratified by gender and urban-rural status. The methods for the creation of Fig. S2 are the same used to create Fig. 3A and B using further stratified sub-groups. Fig. S2A and Fig. S2B represent the temporal trend in median age by race-ethnicity and gender for all tests (Fig. S2A) and for all positive tests (Fig. S2B). Fig. S2C and Fig. S2D show the trend in median age over time for all tests (Fig. S2C) and for all positive tests (Fig. S2D) within each of the three largest race-ethnic groups in North Carolina, stratified by urban-rural status. The median age of testing is higher for men across all race-ethnicity groups, and throughout the testing period. NL White men had the highest median age for testing ranging from 55 to 60 years since April, and Latinx women had the lowest median age ranging from 32 to 38 years since mid-April. Age differences in those who tested positive, however, among different race-ethnicity groups are less prominent. One exception is the consistently higher median age of NL White women that tested positive compared to NL White men starting in early April. The age of testing was usually older in rural areas than in urban areas for all three race-ethnic groups. People with positive tests were usually older in rural areas for all three groups; the median age difference of those with a positive test was much more pronounced between the rural and urban Latinx populations from late March to May.
