@echanda @Probertd8 Maybe? British demographics aren't that different from Irish demographics. As of 2011, white people were 87.2% of the UK's population and 94.2% of Ireland's population. Even if immigrant groups consumed zero cheese, it wouldn't explain Ireland consuming 3.4x more cheese per-capita.
Like, if all immigrants in the UK consumed zero cheese (including white non-Irish immigrants), it would mean that White British + White Irish folks ate 8kg per capita which would still put Ireland 2.8x ahead.
It's hard to overcome a 3.4x gap.
The specific numbers aren't that important. Whether it's 70%, 80%, 85%, or 87.2%, it's not possible to explain a 3.4x consumption gap with differences in immigration.
Even if 50% of the UK were lactose intolerant, it would mean that the other half would only be eating 13.2kg/year compared to 22.5kg. 71% of the UK population would have to be zero-cheese for the remaining 29% to eat 22.5kg/year.
I just grabbed the 2011 UK census numbers and 2011 Irish numbers (the country, not the island) from Wikipedia. It is full UK. But the specifics aren't that important. The UK has marginally more non-white folks, but the gap is many times too large to be explained by that.
