yeah good point and that probably would have warranted a note. it tries to calculate back what the population was for the countries as they are today. there's some questionable interpolation going on.
I would like the alternative, but that would require having a geojson of all historic borders and their populations. and then you'd still have to make a judgement call on Britain -- yes it ruled India, but should India not still show up as its own thing?
