Infographic from PolicyMap Shows Impact of Census Tract Boundary Changes


Drive into any US town and you’ll see the famous population sign. Whether it’s a metropolitan city with a population in the millions or a small farming community populated with more animals than people, the numbers we see on those signs are merely a suggestion.

Census boundaries change all the time — people move in and out of areas, businesses close or open, redevelopment takes place — and these changes make it nearly impossible to accurately compare a region over time. To make this easier, we built translation tables for ever census tract in the nation to make it simpler to see how places have changed over time. And we made this table available for FREE on PolicyMap. Check out today’s blog posting to see how this works in a place like the West Bronx, NY.
