Please check out the other threads on national, racial, and age/year based circumcisions before starting another thread on this. There are plenty of good ones, which will answer whatever you are trying to answer (and search away).
Your current survey is incoherent, and I encourage other users to abandon it. Here is why:
I'm struggling to discover what the OP is trying to uncover here. Blacks who have emigrated from Xhosa South Africa or Muslim Nigeria will be cut, those from Zulu South Africa or Christian Nigeria less likely to be so. Spain (Spanish) is a small European country, almost entirely of uncut men, while Latin America is larger, and somewhat more varied.
I'm a white boy born in England, growing up in South Africa and living in America, and yet, I'm going to be lumped in with all Americans, who are predominantly cut, and I"m not, because I wasn't born in the US.
If I were less lazy I would link to one of the good surveys.
