Understanding Society User Support

Hello,

We use the data in a study that examines the gender wage gap, and we would like to have information about whether individuals live in big cities.

I was wondering if there is a relevant variable, or another variable that I can use to construct a variable for our purposes. I did not find such variables when I searched it on my own.

The only variable I found that is close to it is "urban_dv", but the issue is that the cutoff is 10,000 inhabitants, which is too low for our purposes.

We use waves 1-9 of Understanding Society.

Thank you very much!
