Which communities have an influx of people during the day? Which "bedroom communities" empty out during working hours? In between cooking side dishes for Thanksgiving, I've been working on posting a sortable database of the numbers from Massachusetts. I haven't finished testing and checking it yet, but if you want to take a look at the beta, it's at Daytime Population Data for Massachusetts Communities. Click on a column heading to sort by that stat.
Data is from the U.S. Census Bureau's recently released Daytime Population Analysis for communities throughout the country. A number of local media outlets reported on the results (see for example Globe West's Some Towns Empty Out During Day and MetroWest Daily News's Many Area Communities Serve as Daytime 'Home' to Workers). But what fun are Census numbers online if they're not sortable and interactive?
