Sharad, thanks for your help. I am at a point where I have come to accpet the data as is. The 1991, 2001, and 2011 census codes are a great thing, but they will never line up 100%. The data here: https://egovstandards.gov.in/code-dirctory-land-region-codification is missing locations as if they never existed. villages split into new villages, or join larger towns, and the codes are missing. new villages appear, but it doesn't tell you where they came from or how to split existing towns. The http://lgdirectory.gov.in/ website is missing data as well. I have also found out the the census agency has the links for the data, they sell it. But I believe the data they ship has missing data and corrupt files that do not function 100% for some districts/ states. The last little problem with the census data is that it is missing hundreds, if not thousands of locations. In looking at some village level data, there are clearly two or more different villages/ settlements in some of their village polygons. although OSM and wikimapia are crowd projects, I believe some of the data there is correct. Also, if you can find a good district/ tehsil map and it shows many more locations than what the census has, it makes you wonder what is going on...
thanks for all of your help with this everyone!
