Try an Arcade expression

ArcGIS Arcade is an expression-based scripting language for data in your maps. You can use it to do basic calculations, convert field types, and configure symbols, labels, transparency, pop-ups—all without leaving the map. And you don’t have to be a developer or GIS expert. Arcade is for anyone who wants to transform their data values on-the-fly. Check out the resources below to see how Arcade can enhance your work.

Arcade in action

Watch Jeremy Bartley, Esri’s lead product engineer for web mapping, create an Arcade expression to tell a different story within his map.

Jeremy uses Arcade to change his map from adults with high school education to those without it.

Learn how to create your own expression

A common use case for Arcade is changing the total number of something to a percentage. For example, from the total number of households without a vehicle to the percentage of households without a vehicle. The article Discover patterns in your data with ArcGIS Arcade guides you through the steps.
