A demographic history of Delhi from ancient times, through Independence, and till the present day,using maps and Census data. Caveat- the administrative units described are as of 1st January 2010,on the basis of which Census 2011 was conducted. In 2012-2013, the number of Municipal Bodies increased to 5 because the MCD split into North, South and East MCD. The number of revenue districts increased to 11. Also- apologies for the distorted logo- in the original PPT, it's a rotating gif! Error pointed out by @rkarnad- Tughlaqabad was built by Ghiyasuddin Tughlaq, not Mohammad Bin Tughaq.
