Collection and usage attributes

Age in single years (if aged under one year, record as zero).

If age (or date of birth) is unknown or not stated, and cannot be estimated, use Code 999.

Although collection of date of birth allows more precise calculation of age, this may not be feasible in some data collections, and alternative questions are: Age last birthday?

What was ....... age last birthday?

What is .......... age in complete years?

If collecting age in single years is not possible, age may be collected as a range. Refer to the data element Person—age range, code NN
