Column (5): Age (in years) Ask the age of each member of the household and enter it in column (5). Age is written in years according to the Gregorian calendar rounded downwards.
If the age is younger than 1 year, enter "0". If the respondent does not know his exact age, try to estimate his age by relating his age to important local or national events to obtain a better estimate. To facilitate the estimation, use the conversion tables in appendix 7/8.
