This is a list of the largest urban agglomerations in North America. It includes the 50 most populated urban agglomerations as determined by either CityPopulation.de or Demographia. Please note that Demographia's analytical tool is the "urban area" which may be considered as a narrower construct than the "urban agglomeration" which often include more peripheral suburbs.
