Take any dataset that has multiple columns of data, each with a count of related things. For example, use counts of households by income level or use counts of people by education level.
This map tells the story of predominant race or ethnicity in the United States the way people experience it: neighbourhood by neighbourhood. We can clearly see areas where one race or ethnicity is predominant—revealing striking patterns in many cities. We love how quickly we can see areas where the majority of people are of one race or ethnicity and areas where the population is more evenly balanced.
This map uses bright colours to identify the predominant racial or ethnic group in each area. The strength of the colour indicates how high the population of one group is compared to the next most populous. The map is multiscale, meaning it shows specific things at specific scales. When you zoom out you can see how patterns change when data becomes less granular.
