This interactive data visualization looks at the population changes of the 50 largest cities in the United States since the census started in 1790. The visualization shows the impact of several historical events and the massive effect that air conditioning played on US migration in the 1950’s.
To use the visualization, hover over cells / circles for additional information including city, year of census, population at the time of the census, and census over census change. The end user can also use the filter in the top left corner of the view to toggle between a highlight table view and a map view.
The data for this visualization were sourced from the US census and compiled from Wikipedia.
