The Demographics of Trees in Virginia

For the Geo for Good Summit, Map Nerd Consulting created a poster that looked at the demographics of trees in the state of Virginia.

Many studies have already explored the relationship between forest, tree cover (Riley and Gardiner 2020), and green spaces (Dai 2011), to different demographics such as race (Lu et al., 2021) and income (Holt and Borsuk 2020). I wanted to see what these relationships looked like in my home state of Virginia. The variables I choose to use include: mean forest cover; income; population; and race (Asian, Black, and White). The following poster shows my objectives, methods, results, and potential next steps for this study.
