This is drawings/# of entries in SSP for the Top20 cities.
I bet most North American and European cities (and maybe the cities of a few more countries) has most of their highrises in the SSP database. Wereas many other countries (especially China) has very few of their highrises on SSP.
My hometown has 6 highrises. All on SSP with drawings. So that's 100 %
