What is Voting Age Population (VAP) and how is the estimate calculated?
Voting Age Population (VAP) refers to the total number of potential voters of voting age in a given country. The VAP figure is a rough estimate and it does not take into account the fact that there might be people who are above voting age but still not enfranchised due to legal or systemic barriers. The estimate gives an approximate figure of the number of eligible people but it does not reflect the exact number. VAP might differ largely from the number of registered people since registration in many countries is voluntary or not accurate. In countries where registration is compulsory and automatic, and based on the civil register, for example the Scandinavian countries, the VAP figure and the number of registered voters are quite close.
