This has some 2020 figures and suggests:
~98,995 in EU, 28,615 in APAC (non-china), 22,459 in Canada, and 148,349 in China.
US was estimated at 204,000.
Which means while the US remained their biggest single market, it's barely more than 40% of deliveries in 2020... and with Shanghai continuing to ramp that may be dropping further.
