Hi elderelite, thanks for that suggestion. It's a bit late to be tampering with the survey now that it is launched, because in doing so we are undermining the validity of the figures. However, I will gladly add your "born in" suggestion to the list of amendments for the 2013 survey.
I appreciate your idea. One of the great things about having this survey thread on the forum is receiving feedback such as yours that will improve future surveys.
