Definition: Age in completed years
Age in completed years is the age expressed as the number of birthday anniversaries passed on the date of reference, i.e. the age at last birthday.
"Age" is a basic parameter in survey data analysis since the differences between the population groups constructed on it are relevant in developing many EU and national public policies and programmes. Also, existing information on the situation of specific age groups (elderly or young people) has important implications for the policies and programmes that are targeted towards these categories of population.
