That graphic shows ~44k HNWI emigrating, and ~20k HNWI immigrating. I skimmed the underlying text and didn't see an explanation, so are we to assume the other ~24k HNWI immigrated to the rest of the world's countries in relatively low numbers per country?

I suppose another answer might be that it's easier to track HNWI leaving countries than it is to track them entering other countries?
