Hi Gilles, nice to see you over here ;-)
This is not based on Census at all, bot on 2002/3 images of the MODIS satellite, processed by NASA to classify land cover as habitated or not, rural or urban (funnily enough, part of the criteria is "light at night" - they must have come up with something else for India though, at least in UP there is no power at 3am ;-)...). As such, it pretty accurately reflects the rural/urban divide in terms of physical geography a decade ago - but not necessarily by GoI definition. Its a rough fix until we get a nice, easily browsable list of the ECI's own booth-wise rural/urban classification for 2014... On Tonk and Sawai Madhopur: this is an odd slip-up in the AC-to-PC conversion in my scripts, thanks for noticing. To correct, have a look at the raw data in ruralurban.csv.tgz and re-calculate from the AC list. In the meantime, I shall check what went wrong with the PC classification, Best, Raphael On 13.05.2014 22:52, [email protected] wrote: > Is this 2001 census, by the way?
