    1. The age-standardised out-migration rate is a weighted average of the age-specific out-migration rates, where migration is defined as a person changing their place of usual residence from a household located in one of the SAPRIN surveillance populations to one located outside, and the weights are the proportions of persons in the corresponding age groups of the standard population.

    2. The age-standardised in-migration ratio is a weighted average of the age-specific in-migration ratio, where migration is defined as a person changing their place of usual residence to a household located in one of the SAPRIN surveillance populations, and the weights are the proportions of persons in the corresponding age groups of the standard population.

    3. The age-standardized mortality rate is a weighted average of the age-specific mortality rates, where the weights are the proportions of persons in the corresponding age groups of the standard population.
