there are many british world champions you left out that list and a few mexican champs too where is oscar del hoya canelo Alvarez carl froch ricky hatton randy turpin. I think britain by an inch but both are starting to catch up too usa

Definitely Mexico. Mexico has produced more multi-division world champions and types who reigned and lasted longer than the Brits and perhaps other countries in the world except for USA and the Philippines.

I give Mexico the edge because of JCC, Ricardo Lopez and Salvador Sanchez. Three of these men IMO are greater P4P than the most of these British Boxers.

Mexico of course. The order is and was USA, Mexico, Puerto Rico, Britain and Argentina.

Mexico has produced more world champion boxers than Britain.

1. USA

2. Mexico

3. Puerto Rico

These 3 nations have produced more world champion boxers than any other nation.

Is this a joke? Mexico, and it's not even close.

México by miles, Britans no competition

I would also like to add that more mex amer have one the congressional medal of honor than any other ethnic group.It's the the soul:)
