Age as of Last Birthday and Birth Registration (P5)
Age, sex and marital status are essential for inclusion in a census for purposes of analyzing factors of population changes and preparing population estimates and forecasts. For the POPCEN, age as of last birthday refers to the interval of time between the date of birth and before September 1, 1995, expressed in completed year. Thus, ages are recorded as whole numbers, counting the whole years completed on or prior to September 1, 1995.
Determine the age of each household member by asking the respondent "What is 's age as of his/her last birthday?". Always ask the age of the person even if the date of birth is already given. Do not compute for the person's age from the reported date of birth. Enter the age on the first line provided.
After recording the person's age, ask if his/her birth was registered with the Local Civil Registrar (LCR). If the answer is yes, enter a check on the line provided. If the birth was not registered or the respondent does not know, put an X mark on the second line.
Here are some basic guidelines for your reference:

100 --Y0 105 --Y5
101-- Yl 106 --Y6
102 --Y2 107 --Y7
103 --Y3 108 --Y8
104 --Y4 109 and over-- Y9
1. Do not record ages such as 71/2, 5 years and 2 months, etc. Record the age according to the last birthday prior to September 1, 1995.
2. Check for inconsistencies in the ages of husband, wife and children. The respondent may have given incorrect information for one reason or another. Probe and verify further, as needed. An example is when the mother is only 15 years older than the eldest child.
3. If the exact age is not known, ask for an estimate. It may also help to ask an aged person to recall some well-known local, national or world event in the past by which his age may be associated, or if he is older or younger than some prominent persons. If all possible means have been exhausted and the respondent is unable to give the correct information, enter his best estimate.
4. There must be a report of age in P5 for every household member.
Age as of Last Birthday Conversion Table (Appendix 9) will help you check the reported age of a person against his date of birth. Refer to this table when checking your entries on age for consistency.
