Laravel - Populating dropdown with two columns as display type

I am using the pluck api to get two columns and make a collection be passed in the view to make a dropdown menu.

Province::pluck('name', 'id');

It works fine and Province 'name' is displayed and id is used value. But I want to display two columns i.e name and total_population.

How can I do this?
