This map shows every single job in the US in 2010
Inspired by Dustin Cable's racial map, Harvard PhD student Robert Manduca plotted another incredibly detailed map of every job in the US. Or at least every job in 2010 (the most recent census data year). Manduca's map breaks down professions by color: factory and trade jobs are red, professional jobs are blue, health care, education, and government jobs are green, and service jobs are yellow.
Manduca credits Cable with sharing his code online transforming what might be a work-intensive project of a "dataset and an idea to a finished visualization" quite easily.
He goes further on to say:
Dot maps like this one and the racial dot map are particularly useful for visualizing density, especially of people. There’s a certain simplicity to them— one dot equals one job or one person— that makes them powerful and relatively straightforward to interpret.”
The beauty of Manduca's map is its ability to easily chart and visualize large sets of data. One can simply look at the map and not only see that jobs are clustered in major metropolitan cities but also see how job sprawl affects nearby suburbs.
