Great stuff! I can see a lot of potential with this. I think most of the information you provide for each area are very useful. Love the focus on zipcodes - much better than a city as a whole.
Couple comments: Some of the data/charts are hard to understand right off the bat. I'm not sure it will be clear to everyone what certain scores mean to them. I think it might be useful to take a look at how https://nomadlist.com/ does it.
This is probably obvious to you, but it would be nice to have more tangible and qualitative data for each area. School ranks, violent incidents, etc. are important, but there's so much more that goes into making these decisions! I'm not sure how you'll get this qualitative data unless user-generated, but I think it's critical.
Depth (not just breadth) is very important. E.g. I think people are more likely to use a "here's a complete look at X city" than a "here's a brief look at EVERY city!"
Love what you're doing. Who is your ideal demographic right now? Young families?
