Voting Age Population Share
Compute the share of the total population that has reached voting age (18 and over) as a percentage.
Description
Compute the share of the total population that has reached voting age (18 and over) as a percentage.
Compute the share of the total population that has reached voting age (18 and over) as a percentage.1
When to use Voting Age Population Share
Use this indicator to compare age-sex structure after placing every count in the stated age bands and using the same population reference date.
- VAP
- Population aged 18 and over.
- Total
- Total population of all ages.
How the method works
- VAP share %
- Voting-age population as a percent of the total population.
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.
