Two editorial errors occurred in this paper by Nigel Fisher and colleagues (1 January, pp 27-30). In table II all population subgroups should have been divided according to age <30 and >=30 years [not age <30 >30 years]. In the first sentence of the appendix the equation to calculate the total population should have read NT=(N1xN2/N [not NTx(N1=N2)/N]
