One "real number" is actually rather far off - survey respondents estimated that 49% of people "own a home" but the article implies the actual number is 65%.
65% is the oft-cited "home ownership rate", however that is defined as the fraction of occupied homes with an owner in them. Move back in with your parents after college? Rent from a live-in landlord? Congrats, you "own a home" according to this absurd statistic.
A much more reasonable number would be something like the percent of adults who either own a home or are married to someone who does.
