Reply to comment by neutronicus in Baltimore neighborhoods Mondawmin, Bolton Hill face different realities due to city’s history by GovernorOfReddit

I know the person who did that web app - it’s because the article just uses census tracts whereas the DoP used census blocks and aggregated up into custom geographies using a proportional split methodology, followed by some slight hand-aligning of groups to new geography. This means that some neighborhoods might have about 5-10% margin of error in population, however it’s important to remember that app is to provide general context/understanding with Baltimore’s super custom neighborhood geography

Thanks for the explanation!

Figured it was some kind of binning discrepancy - to be clear you’re saying the DoP one has the 5-10% margin? Or the one presented in the article

DoP

And less binning and more different geographies/sampling methods.
