It will only amount to 3% of the US population. China’s cut out amounts to 13% percent. A 1.41 billion is a lot of people and I understand they don’t want to skew the results. If just taking account that slice, which a quick search says it’s 180 million people, that reading is more than half of the US population. It’s a matter of scale. I’m sure they can add some other provinces to total the US population and still have a higher score.
