Cases Demographics View Larger Cases Demographics Where does the demographic information come from? Why are data missing? Any demographic information for cases or deaths that was included on the laboratory report is included on the NC COVID-19 data dashboards. Information most commonly included is age, and occasionally gender. Additional data on demographics are obtained through case investigations by local health departments (LHD). When someone tests positive, the LHD contacts the person to obtain additional information. Some people may choose not to disclose this information to public health or could not be contacted. More information becomes available as case investigations are completed, but information is not available for all cases. Demographics shows the number and percent of cases and deaths by age, gender, race, and ethnicity. All percentages for demographic data on the NCDHHS website are calculated using cases with known information on that metric (e.g. percent of cases by race is calculated among cases with data available on race). Data for both molecular (PCR) positive and antigen positive cases are included in the demographic data. The number of cases and deaths that are missing demographic information from the laboratory report are displayed as 'Missing Data' on the NC COVID-19 Data Dashboard.
