The other day I noticed that one of my favorite websites, the Post-Dispatch's building age map, doesn't seem to be working any more. I emailed the online editor to see if they can get it back up and running. Can anyone (with more technical expertise than I have) tell what the issue seems to be?                 https://www.stltoday.com/news/multimedi ... a9ddb.html

City data on year built for 1800s is very inaccurate . For alot of the buildings they just use a default year

I wrote to the P-D about this last year, and am thrilled that they've gotten it back up and running. You should definitely take any individual parcel's given year with a grain of salt, but it's very useful to see when neighborhoods were generally built (and where outliers are).
