Using this text for the link is fine, but can you format this so it's more readable? Maybe something like "Date to age group" or something that describes the function to be used.

I just realized this doesn't deal with Date fields. It's still numbers...so it could be even more generic, like "Number to category"


This expression assigns a value of a certain age group based on the value of a number column.

## Use cases

To categorize your age data into age groups for easier analysis and visualization.

## Workflow

Create a new field of type "String" in your feature layer and name it "AgeGroup". In the "field calculator" create the following Arcade expression:

// replace "applicant_age" with the name of a number
// field in your layer
var numberField = $feature["applicant_age"];

When(
numberField < 15, 'Under 15',
numberField >= 15 && numberField < 25, '16-25',
'NA' );

In the above expression we only had two categories ('Under 15' and '16-25') but you can add as many categories as needed.

You need to always have a default value at the end of expression (in our example - 'NA') or you will recieve an error.
