A nifty map pinpoints practically every job in the United States, revealing the economic character of America’s metropolitan areas, which also helps to inform the local culture.

The interactive graphic, created by Harvard PhD student Robert Manduca, is made up of color-coded dots: red represents manufacturing and logistics, blue is professional services, green is healthcare, education and government, and yellow is retail, hospitality and other services.

“These kinds of maps are great when you’re talking about individuals,” Manduca told CityLab. “Especially when you’re talking about jobs, because jobs are more concentrated than people. It gets across how tightly packed they are in many U.S. cities.”
