I agree, it sounds like a two-way table of income group by country:
-tabulate-, with the desire being to count the number of individuals in
each income group. Ultimately I would guess the objective is to compare
the profiles of each country. The word "paired test" just makes no sense
to me in this context, but I could be confused. 

It is a

I guess. I'm always uncomfortable with "nonparametric" because a lot
(most? all?) of nonparametric procedures are estimating *some*
