8 years ago So I created some maps of the gentrification status using the UHF34 and some other smaller geographies for comparison that you can see in this document.
On Monday we should talk over what we think about this issue and whether we think it's worth pursuing this topic still.
I was looking around a bit more at the CHS data and there are a few more issues with it than I initially noticed. The main one being that there are different versions of the UHF neighborhoods. The smallest ones are UHF 42, and that's what I found online map we have been looking at. However, in the CHS data they don't report the data using that version - its mostly using UHF 34 - so grouping many neighborhoods together. Even more annoying, in 2002 they use another version UHF 33, but this is more than just a collapsing of two neighborhoods - there are some collapsing/splitting going in both directions between the 33 and 34.
Also, the multi-year weights are only available for 2002-2008 so I don't know how they deal with the boundaries changing between years within this yet. I'll look more into this and let you know.
Some good new is that the CHS people responded super quickly to my email to sign up for updates about changes/releases for CHS) so if we need to we can ask them and they might have some helpful info about all this.
Anyway, we might beable to still make this work, but there neighborhoods are looking pretty large in the 33/34 versions. I'm kinda worried that with areas this large we won't be able to pick our gentrification at al in a lot of cases.
Here's a helpful map of the three UHF versions.
