Splitting the US by Population

Posted In: Geography | Maps

This visualization lets you divide the US into 1,2,3,4,5,8 and 10 different segments with equal population and across different dimensions. The divisions are made using counties as the building blocks (of which there are 3143 in the US). There are numerous different ways to make the divisions. This lets you make the divisions by different types of geographic directions and divisions by population density.

Instructions

  • Select a dimension on which to divide up the country – there are geographic dimensions, like north to south or east to west, or by population density
  • For some geographic divisions (concentric rings or pie slices), you can choose the geographic center of the divisions
  • You can also choose the number and color scheme of the divisions
  • To show the divisions, either click the Animate Counties button or use the slider to add counties

If you can think of other interesting ways to divide up the US, please let me know and I can try to add them to this visualization.

Sources and Tools:
2018 county population data is from US Census Bureau. The map visualization is created using the Leaflet javascript mapping library and the data wrangling and user interface and interactivity are created using HTML, CSS and Javascript code.

    Now I’ve seen population dis-aggregated by counties, by latitude, by longitude — how about altitude?
