Lum's second question about the respondent's date of birth suggests that they were concerned with the reliability of the measurement, particularly ensuring that the responses were accurate and consistent. If someone gives their age as 30, for example, they could have just turned 30 or be close to 31 - the date of birth question would help confirm their true age and check for inconsistency in responses.
