To better understand a city's size, look not to its resident population total but to its daytime population. 'Commuter-adjusted populations' have implications for everything from emergency evacuation procedures to transportation infrastructure.
Emily Badger dissects information from "a new report from the Census Bureau using data from the American Community Survey" on the fluctuations between evening and daytime population totals experienced throughout the United States.
"'Commuter-adjusted populations' tell us a lot about where the jobs are and which communities do little more than give people a place to sleep. Count people where they work, and not where they live, and the resulting picture also further blurs the divide between cities and suburbs (and how we think about who is invested in which places)," she explains.
