High concentrations map

Data allows us to see and quantify where things are happening. When creating maps about behaviors among the population, we tend to see patterns based on where most people live. Overcome this by showing the value as a percentage of the total. For example, this map shows us where people speak Spanish at home, based on data from the American Community Survey. To identify concentrations of Spanish speakers, use an Arcade expression, much like a Microsoft Excel formula.
