First up is a link to a story on the growing housing crisis across Ohio, with a focus on the Columbus area.

The article uses an interesting metric to quantify just how bad the housing shortage is in counties across the state- the number of jobs versus the number of available housing units. In Columbus, there is only about 0.7 units per 1 job, leading to a Central Ohio shortage of more than 200,000 units!

Second, here is a link that gives the average annual carbon footprint of all US zip codes. In general, it seems that the most urban zip codes have the lowest footprints, along with far rural areas. The highest footprints seem to be in suburban and exurban areas. In the Columbus area, the zip code with the highest carbon footprint is 43021, which contains much of Westerville. Second highest is 43054, which contains New Albany. Take a look at the interactive maps here: https://coolclimate.org/maps
