Garrett Dash Nelson and Alasdair Rae have identified 50 regions of the United States based on distinct separate labor markets. The new identified megaregions of the United States were determined by analyzing over 4,000,000 commuter journeys.
You can view the results of this analysis of commuter journeys in the USA on the Megaregions of the United States interactive map. The map shows the borders of the identified megaregions. It also shows the commuter journeys which determined the shape of each of these new megaregions. If you hover over any of the megaregions on the map you can view the name that Nelson & Rae has given the megaregion and the name of the major city at the center of its distinct interconnected labor market.
The map is powered by the Leaflet.js mapping library. The data itself was made into slippy map tiles by using QTiles, a QGIS plugin for creating raster map tiles for interactive maps.
