Compute the ageing index, the number of persons aged 65 and over per hundred children under age 15.
Description
Compute the ageing index, the number of persons aged 65 and over per hundred children under age 15.
Compute the ageing index, the number of persons aged 65 and over per hundred children under age 15.1
When to use Ageing Index Calculator
Use this indicator to compare age-sex structure after placing every count in the stated age bands and using the same population reference date.
- Pop 0-14
- Population aged 0-14 years.
- Pop 65+
- Population aged 65 years and over.
How the method works
- Ageing index
- Persons 65+ per 100 persons under 15.
Limitations and assumptions
Fixed age thresholds are conventions rather than biological boundaries. Migration, cohort shocks, institutional populations, and different age-band definitions can alter comparisons.
Alternative or Complementary measures
Show the underlying age-sex counts or population pyramid beside the summary ratio. Alternative dependency thresholds can test whether a conclusion depends on one conventional age boundary.
