AAMR – Age-Adjusted Mortality Rate
*
Age-adjusted mortality rate only calculated for overall and by gender. Age-specific rates were calculated by age group and are, therefore, not age-adjusted.
†
The misclassification rate ratios by age group are not age-adjusted, but age-specific rate ratios
‡
Unknowns: n=2 for age groups before IHS linkage, n=4 after IHS linkage; n=8 for sub-state planning districts before IHS linkage and n=11 after IHS linkage
