Analyzing Karnataka's Census data

133 users have liked.

Come 2011, and we will have our once in a decade census done. If the projections prove right (, then Karnataka would be pegged at ~ 5.94 crore people.

My interest however is detailed data for each state like whats in here ( It's a potential goldmine for analysis. Can we reach out to influence their questionnaire to add more data points of interest, or is it too late now!? Think of things like language, rural-urban migration, access to healthcare, use of BPL facilities, impact of NREGS etc.

Go through the Karnataka sheet to see for yourself on how nice the data points are and nicer they could be if some more questions were to be asked during the upcoming census.


Condition of Census Houses  Total   Rural   Urban %
Total: 10,232,133 100% 6,675,173 100 3,556,960 100%
Good 4,491,851 43.9% 2,414,280 36.2% 2,077,571 58.4%
Livable 5,234,234 51.2% 3,873,692 58.0% 1,360,542 38.2%
Dilapidated 506,048 5% 387,201 5.8% 118,847 3.3%

So few households in 3rd category, even in rural areas, interesting.

Or sample this - Type of Drainage Connectivity for Waste Water Outlet:

Type of Drainage Total % Rural % Urban %
Total Households 10,232,133   6,675,173   3,556,960  
Closed drainage 1,766,563 17.3% 285,507 4.3% 1,481,056 41.6%
Open Drainage 3,475,862 34% 2,076,967 31.1% 1,398,895 39.3%
No Drainage 4,989,708 48.8% 4,312,699 64.6% 677,009 19%

58% (39.3 + 19) of even urban households don't have access to a regular drainage connection.

I don't know how exactly the census is done, yet to learn and understand.

Census 2011 with more data

62 users have liked.

I think census 2011 will extract much more data than what we have from 2001 census, which itself had been hailed as revelutionary by UN, etc. Steps are already underway to use IT in a big way for census 2011. See below:


The preparations for the 2011 Census have begun. Recently, a conference on “Technology Options for 2011 Census” was held on 3rd and 4th December 2007 at New Delhi. In the Conference experts from Government and industry presented their views on data collection through paper (for scanning & ICR purpose) and on using Hand Held devices for direct data entry in selected urban areas, to begin with. The consensus was by and large to continue the use of improved ICR Technology for 2011 Census along with experimenting and doing trial runs to assess the cost effectiveness and workability of the combined use of technologies. This exercise would be carried out further during 2008-2009.

The Census 2001 has been exceptional in more than one way. The foremost thing about this census has been that all tabulations are based on 100% count which is unlike previous censuses when sampling was resorted to. The use of intelligent Character Recognition (ICR) technology has made it possible. Besides this is first census of the 21st century and the new millennium. Therefore, Census 2001 results will become the benchmark for future censuses. The data on economic indicators and, in particular, the structure of the workforce shall help in measuring the effect of the structural changes taking place in the economy since its deregularization and decontrol.

The following pages of the publication provide highlights from the results of Census 2001 and other useful information for familiarizing the users about the vast array of data collected and published In Census. A catalogue of select data products (e.g., books, CDs, maps, data sheets, etc.) is also provided, which will give an idea information being made available by the Census. Details about the new facility being extended by the census organization for giving customized tables and maps based on user’s requirement, are also given.
