1 Number of children below five years.

2 IMR, CMR and U5MR are rates per 1,000 person-years. Estimated mortality rates are in italics. IMR = Infant Mortality Rate (0–1), CMR = Child Mortality Rate (1–4 years), U5MR = Under-five Mortality Rate (0–4 year).

3 Whole population and not under-5 year population.

4 Rates per 1,000 mid-year population
