  • NHH: non-household; Svy: survey; Est: estimate.

  • Census data on the size of total population, size of non-household population and proportion of adults in the national population were obtained from India 2001 Census, Cambodia 2004 Inter-Censal Survey, Ghana 2000 Census, Uganda 2002 Census, Lesotho 2006 Census.

  • In India, the actual proportion of non-household adults in the census was 56.15%, much lower than 66.67% and 75.00% assumed in scenarios B and C.

  • In Ghana, the estimate of non-household population refers to homeless population only.

  • In Lesotho, the estimate of non-household population refers to institutional population only.
