Understanding Society User Support

Hello,

I was wondering if you could help me with a query I have about your Wave 6 income data.

We are wishing to run some cross tabs looking at gross monthly income (f_fimngrs_dv) but we are unsure how best to categorise this as we don't understand what the minus numbers represent?

Could you also please outline how you have derived the variable? We are unable to find this information on your website.

Thank you very much for your help

Best Wishes
Katrina
