Hmm… 1 in 20 individuals are affected… I get the idea being 2 adults per family, one of them affected, hence 1 in 10 families, but I think its incorrect/misleading (potentially in either direction) to say 1 in 10 families. I haven't looked at the data about how many families are single parent (which could increase the impact per family) OR how many of those 5% identified as working multiple jobs are married (I wouldn't be surprised if more of them are unmarried, since a two parent family with both working one job might be expected to not need the additional jobs).
