Waldo Tobler, an American geographer, once said: “Everything is related to everything else, but near things are more related than distant things.” In my last blog post on diversity indices, we found that high diversity index scores across the state made it hard to draw any concrete conclusions about variations in racial, ethnic, and birthplace diversity across Hawaii’s census tracts. Tobler’s words of wisdom, his “First Law of Geography,” instead directs us to compare data at a more local scale.
