Potential Support Ratio Calculator
Compute the potential support ratio, the number of persons aged 15-64 per person aged 65 and over.
Description
Compute the potential support ratio, the number of persons aged 15-64 per person aged 65 and over.
Compute the potential support ratio, the number of persons aged 15-64 per person aged 65 and over.1
When to use Potential Support Ratio 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 15-64
- Population aged 15-64 years.
- Pop 65+
- Population aged 65 years and over.
How the method works
- PSR
- Working-age persons per elderly person.
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.
