Interviewer instructions
1. Date of birth:
The date of birth will automatically be converted to complete age on the day of the census.
Many regulations and public measures (compulsory school attendance, legal age and the like) are directed at different age groups.
The age structure of the population is used as a frame of reference for numerous statistical measures. Gender and age are requirements for the calculation of life expectancy and for population projections. The development of the age structure for the pupils, employed and retired persons will have more meaning in the coming decades than changes in the population in itself.
