If I take population, segment by age group (say there are 10 M people in the 20-40 years category), can I find the # of couples in this age group by just thinking of it as 10 M people so that's 5M "pairs", I'll assume 30% are single and remaining 70% are couples..(so it's 70% x 5M pairs). Or is there another way to do this?
