Hi all, I created a new field on my layer (area in sqmi) in hopes of using this to normalize population data and create a density map via the 'Transparency by attribute' route, however, no matter what I do this newly created & calculated field does not show up as an option. It shows up in the attribute table and the fields list, but I am unable to select it as a 'Divided by' field.

What can I do to get this field to appear?

That options requires a numeric field.  it appears as if the AreaSQMI field you added is text:

I should also add that the field doesn't show up as an option for transparency field, either, but I'm able to access it with the Arcade expression option (the "</>" button)...

You are right, thanks! Sorry to waste your time; I had tried to delete the post after I discovered that.
