I was curious to answer the question, is voter registration in California a contributing factor to lower voter turnouts? To answer this, I found relevant data containing county populations and county voter registrants by age. Using the Plotly library, I created a couple of bar charts to help shed some light on my question.
As is typical, it left me with more questions than answers. Take a look for yourself.
How It Works
The data relevant to answering this question lives in a large JSON array. It contains the name of each county in California and their respective populations (of voting age) in addition to how many are registered (separated by age group). This data lives in an S3 bucket on AWS.
I query the data and manipulate it to show the percentiles for each age group. This shows us the age make-up of registered voters. I only display the top 10 most populated counties for simplicity.
