In the course of preparing for a talk, I was entering household expenditure data on communication-related activities into a spreadsheet that contained data from the 2009-10 Household Income and Expenditure Survey (HIES). In the three years since 2009-10 many things have happened to expenditure patterns, but one thing jumped out.
In 2009-10 a household reported an average expenditure of LKR 382.72 outside the home per month. In 2012-13, this had declined to LKR 17.19. The overall telecom expenditures in-home and out-of-home had actually increased from LKR 728.08 to LKR 845.58. What had changed was the mix. This clearly shows that people have stopped using communication bureaus and payphones and are using mobiles instead.
