Demographics

These visualizations explore the relationships between demographic variables (age, sex, race, and ethnicity) and Covid-19. The intent here is to examine some of the health disparities across these groups. Each visualization can help us learn more about this topic, and key questions are posed in order to prompt the reader.

COVID-19 data source: Hamilton County Health DepartmentCOVID-19 vaccination data source: Tennessee Department of HealthPopulation data source: US Census Bureau 2018 ACS-1 Year EstimatesNote: Demographic data includes Hamilton County residents only. Demographic data shown here does not include pending data, which can represent a significant portion of the total.

Age

Case and death rates by age range

Key Questions: How has the virus affected different age ranges? What are the differences in case rates across age ranges? What are the differences in death rates across age ranges? What about the ratio of cases to deaths (case fatality rate)?

This chart shows case and death rates for each age range. The left vertical axis indicates cumulative cases per 100,000 residents (red columns), and the right vertical axis indicates cumulative deaths per 100,000 residents (black columns). Note the vertical axis scales. If the case and death rate column heights match for a given age range, the case fatality rate would equal 1%.

Cumulative case rates for age ranges over time

Key Questions: How has the virus spread among different age ranges over time? Were particular age ranges affected more or less during certain time periods?

This chart shows the cumulative case rate for each age range over time. Each line shows the cumulative number of cases per 100,000 residents for each age range.

Monthly new cases by age range

Key Questions: How have different age ranges contributed to new monthly cases over time? Were there periods of time when case increases affected a particular age range more or less?

This chart shows new cases by month for each age range.

Proportion of weekly new cases by age range

Key Questions: How have different age ranges contributed to total new cases over time? Were there periods of time when the proportion of new cases among a specific age range was lesser or greater? When did major proportional shifts occur?

This chart shows the proportion of weekly new cases by age range. The total percentage of cases for each week is broken down by age range.

New cases among school-age children by day

This chart shows daily new cases among school-age children in Hamilton County and the 7-day moving average. Data source: Tennessee Department of Health.

Sex

Case and death rates by sex

Key Questions: How has the virus affected females and males? What are the differences in case rates between the two? What are the differences in death rates? What about the ratio of cases to deaths (case fatality rate)?

This chart shows case and death rates for each sex. The left vertical axis indicates cumulative cases per 100,000 residents (red columns), and the right vertical axis indicates cumulative deaths per 100,000 residents (black columns). Note the vertical axis scales. If the case and death rate column heights match for a given age range, the case fatality rate would equal 1%.

Vaccination rates by sex

Key Questions: How have vaccines been administered across females and males? What are the differences in vaccination rates between the two?

This chart shows vaccination rates for each sex. The vertical axis indicates total recipients (individuals receiving at least one dose) per 100,000 residents (green columns). Source: TDH

Race & Ethnicity

Note: Race (White, Black, Asian, Other) and ethnicity (Hispanic, Non-Hispanic) are separate demographic variables. They are shown together in the first two charts for comparison purposes.

Case and death rates by race and ethnicity

Key Questions: How has the virus affected different race and ethnicity groups? What are the differences in case rates across the different groups? What are the differences in death rates? What about the ratio of cases to deaths (case fatality rate)?

This chart shows case and death rates for each race and ethnicity category. The left vertical axis indicates cumulative cases per 100,000 residents (red columns), and the right vertical axis indicates cumulative deaths per 100,000 residents (black columns). Note the vertical axis scales. If the case and death rate column heights match for a given age range, the case fatality rate would equal 1%. Race and ethnicity are separate demographic variables—they are shown together in this chart for comparison purposes.

Vaccination rates by race and ethnicity

Key Questions: How have vaccines been administered across race and ethnicity groups? What are the differences in vaccination rates across the different groups?

This chart shows vaccination rates for each race and ethnicity category. The vertical axis indicates total recipients (individuals receiving at least one dose) per 100,000 residents (green columns). Race and ethnicity are separate demographic variables—they are shown together in this chart for comparison purposes. Source: TDH

Cumulative case rates for race and ethnicity categories over time

Key Questions: How has the virus spread among different race and ethnicity groups over time? Were particular groups affected more or less during certain time periods?

This chart shows the cumulative case rate for each race and ethnicity category over time. Each line shows the cumulative number of cases per 100,000 residents for each race (White, Black, Asian, Other) and ethnicity (Hispanic, Non-Hispanic) category. Race and ethnicity are separate demographic variables—they are shown together in this chart for comparison purposes.

Weekly new cases by race

Key Questions: How have different race groups contributed to new weekly cases over time? Were there periods of time when case increases affected a particular group more or less?
