Question 32: What is your date of birth?
The day, month, and year of birth are recorded. The age, in completed years, is recorded and the circles corresponding to the recorded age are filled in.
On pages 76 and 77 of this manual, two tables are given that will facilitate the calculation of age, given the month and year of birth.
Either the table June to November or December to May, according to the month of birth, should be used.
If the date of birth is unknown, only the age in completed years is recorded and the corresponding circles are filled in.
Some informants cannot remember their exact age or their date of birth but they know, however, that they were born in conjunction with important historical event. On page 75 of this manual there is a list of events to be used as a guide that will allow the approximate age to be estimated.
