Arcade<\/a> is an expression language that allows you to define custom content in ArcGIS applications for desktop, mobile, and the web. Arcade expressions give you the flexibility to create dynamic popup elements,<\/a> calculate new values<\/a>, and format data. In this post, I\u2019ll demonstrate how you can use Arcade to map diversity.<\/p>\n

First, I’ll provide details describing my methodology, then we’ll explore the results with a ton of maps.<\/p>\n

Diversity index<\/h2>\n

When the 2020 United States Census numbers were released, the summary of responses showed the U.S. is more diverse than ever<\/a>. In the context of demographics, diversity usually refers to the level of variation that exists in a population with respect to race and ethnicity.<\/p>\n

In fact, Esri provides a diversity index<\/a> that returns a value between 0-100 for each census tract in the U.S. A diversity index indicates the probability that two people selected at random within an area belong to a different race or ethnicity.<\/strong> Therefore, higher numbers indicate more diversity.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":1549112,"id":1549112,"title":"race-diversity","filename":"race-diversity.png","filesize":189967,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2022\/04\/race-diversity.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-online\/mapping\/create-a-diversity-index-with-arcade\/race-diversity","alt":"Racial and ethnic diversity of the southeastern United States (2021).","author":"6561","description":"","caption":"Racial and ethnic diversity of the southeastern United States (2021 Esri Diversity Index).

Languages spoken at home<\/h2>\n

Occasionally I like to explore data in the ArcGIS Living Atlas of the World<\/a>. The Living Atlas has a treasure trove of data, including up-to-date data from the American Community Survey (ACS)<\/a>. I load the data in the ArcGIS Online Map Viewer<\/a> to see if I can learn something new by experimenting with various Smart Mapping styles<\/a>.<\/p>\n

Recently, I came across this layer<\/a> containing data for languages spoken in the home. It reports the number of people speaking languages in the following categories:<\/p>\n
