Here's where people move when they leave Denver

I crunched nine years of voter records to analyze movement patterns within Colorado, then cold-called a bunch of people to find out why they left the city. Most people simply couldn't afford to stay. Concerns about crime also made the suburbs more appealing to some.

A Denver HOA in Green Valley Ranch is threatening to foreclose on homes over aesthetics

What's the latest with COVID-19 cases in Denver?

This is generated by a program that scrapes state data every day and compiles the numbers in a spreadsheet, which feeds the graph. The graph lived in a web embed that was embedded on Denverite and in the newsletter – it became outdated when COVID case rates ceased to be relevant (in part due to at-home testing), so I stopped updating it. We still use the CDC transmission rating in our daily emails.
