This data analysis was done using the Provisional COVID-19 Deaths by Race and Hispanic Origin, and Age dataset provided by the NCHS/DVS, which contains data on deaths involving COVID-19, pneumonia, and influenza, categorized by race/age/jurisdiction.
There are 13 columns listed:
Date as of - date of analysis
Start date - first date of data period
End date - last date of data period
State - jurisdiction of occurrence
Age group - age group
Race and Hispanic Origin Group - Race or Hispanic origin group
Pneumonia, Influenza, or COVID-19 deaths - deaths with any of aforementioned codes.

We can now start to analyze the data and make some plots. For example, we can look at the relationship between COVID-19 deaths and total deaths across different age groups or states.
We can also explore how pneumonia deaths relate to COVID-19 deaths, or how influenza deaths compare across different race and Hispanic origin groups.

As seen above, California has the highest total deaths, followed by Texas and Florida. The top 10 states account for a significant portion of the total deaths in the dataset. Now we can look at the relationship between COVID-19 deaths and total deaths across different states and variables.

The Top 10 States by COVID-19 Deaths plot shows that California has the highest number of COVID-19 deaths, followed by Texas and Florida, similar trend to total deaths. It’s a good idea to perhaps explore how age groups and race/origin groups are affected, or effect these trends as well.

Fit1 shows that there is a statistically significant relationship between age group and COVID-19 deaths (p < 2.2e-16), with older age groups having higher COVID-19 death counts. The model explains approximately 85% of the variation in COVID-19 deaths among different age groups (R2 = 0.8505; adjusted R2 = 0.8478). The prediction error rate is 1,234 deaths (F= 305.3, p < 2.2e-16).
Fit2 indicates that there is a statistically significant relationship between race and Hispanic origin group and COVID-19 deaths (p < 2.2e-16). The model explains approximately 60% of the variation in COVID-19 deaths among different race/origin groups (adjusted R2 = 0.5958).
The prediction error rate is 1,567 deaths (F= 120.5, p < 2.2e-16). This suggests that race/origin group is an important factor in understanding COVID-19 death counts.

This graph looks at COVID-19 deaths by age group and race/origin group. The left panel shows that COVID-19 deaths increase with age, with the highest counts in the 85+ age group. The right panel shows that certain race/origin groups, such as Non-Hispanic Black and Hispanic, have higher COVID-19 death counts compared to Non-Hispanic White and Non-Hispanic Asian groups. While it shows disparity in deaths across race/origin groups, it is important to consider other factors such as socioeconomic status and access to healthcare, which are not shown in this dataset.
Note: Chatgpt was used to assist with code writing, color palettes, and brevity. All interpretations and conclusions were made by me.
