I'm looking for a data source that would allow me to generate a lat/long that is "probable location of a human's home". I'd hope that if I ran it ~8 billion times, it'd give me something 'similar' to the distributions of humans on the planet at any given time.
I'm comfortable with the data being very rough — it'd be ideal if I could get single digit number of different lat/long 'bins' for a major metropolis for example (eg. the east side of NYC has an X% chance of hosting a human, the west side Y%), but not a requirement — whole city level 'bins' would be fine too.
I live in the UK, so I'm reasonably familiar with the ONS, which I'm sure has data I can use for my country, but is there anything global I could lean on?
