Adult and Old Age Mortality: Estimates derived from: (a) recent household deaths data by age and sex from the 2004, 2010 censuses and 2007, 2016 DS; (b) recent household deaths adjusted at adult ages for underregistration using death distribution methods; (c) estimates of under-five, adult and old age mortality.
