Question 34a: What is the solar calendar month and year of your last birth? The last birth is the "live" birth of the respondent closest to the census day, irrespective of whether the child is still living or had died, and irrespective of whether the child is currently living in the same or in a different household. The guide on asking and recording Question 34a is the same as that on asking and recording Question 4 "Calendar month and year of birth" (see the guide on asking and recording Question 4).
