^a Age- and sex-specific deaths deviate slightly from the totals reported in the text because 27 deaths had no age data.

^b Number of deaths reported by the Commune Health Centre, the Commune Population and Family Planning Committee (CHC/CPFPC) and the Justice Department.

^c Number of deaths reported by the CHC/CPFPC but not by the Justice Department.

^d Number of deaths reported by the Justice Department but not by the CHC/CPFPC.

^e Estimated number of deaths missing from CHC/CPFPC and Justice Department sources.

^f Proportion of estimated deaths derived from the list obtained by reconciling the Justice Department and combined CHC/CPFPC lists. Derived with the following formula: (a + b + c) ÷ (a + b + c + x) × 100.
