(January 30, 2008)

The margin of error in the survey, conducted in August and September 2007, was 1.7 percent, giving a range of deaths of 946,258 to 1.12 million.

ORB originally found that 1.2 million people had died, but decided to go back and conduct more research in rural areas to make the survey as comprehensive as possible and then came up with the revised figure.
