The numbers for Hyderabad and Rangareddi districts in the state of Andhra Pradesh (in South India) show 3.1% and 7.3% respectively. Considering that the state capital and its metropolitan area are in these two districts, I expected highest numbers of people owning said "assets". But these two had lower numbers compared to other districts. Then I came across the earlier post "We are the 5%" (http://datastories.in/blog/2013/04/01/indias-5-percent/ http://datastories.in/blog/2013/04/01/indias-5-percent/), which had a similar map showing the "% of Households with TV, Computer, Phone and Vehicle, by District". This map shows Hyderabad with 22.7% and Rangareddi with 15.8%. These of course are more likely numbers. Since TV and phone were among the lists of assets in both posts, the first set of numbers should be more in line with the second set. How is this discrepancy explained?
