>The refusal to gather statistics on ethno-racial diversity is unusual Is this true? I don't understand why any country would want to open the box of pandora that is gathering statistics on ethno-racial diversity. I always thought countries like the USA and China were the exception.
Just off the top of my head for countries that also track ethnicity/race in government statistics: Belgium (because the Walloon/Fleming ethnic divide is so central to its politics), Germany (under the euphemism "migration background"), Russia, Israel, Lebanon... Ethnicity is an extremely important identity category, and if you want to manage that diversity you need information.
That's very different from the US keeping track of race though. After a generation there's no way for the German government to tell the children from naturalized citizens from other German citizens.
