His & Her bedrooms... zzzzz

One thing we love to do here at the _floss is drop historical perspective. It's something that separates us a bit from all the other smart websites out there. Yeah, you learn something new here, but hopefully you also learn something old, as well.
Along those lines, dig this: An article in the New York Times the other day began thusly, "Not since the Victorian age of starched sheets and starchy manners, builders and architects say, have there been so many orders for separate bedrooms."
Now, while it would have been nice to know how many orders for separate bedrooms there were in the late 1800s, and in what country these orders were being placed, the Times is nothing if not diligent when it comes to fact checking, so I'm going to take their word for it.
I'll also assume the whole separate bedroom thing back then had everything to do with sex and decorum (if you think otherwise, please, drop a comment). That's not the reason orders on the same are up today, however. Nope, nowadays it's more about the actual shuteye; the same reason so many people have prescriptions to sleeping pills. Check out these interesting stats from the article:
In a survey in February by the National Association of Home Builders, builders and architects predicted that more than 60 percent of custom houses would have dual master bedrooms by 2015, according to Gopal Ahluwalia, staff vice president of research at the builders association. Some builders say more than a quarter of their new projects already do. Or separate sleeping nooks. Or his-and-her wings.
My question to you, dear faithful readers of this blog, is this: whaaaaaaaaa?
60 percent of custom homes? Is it that I don't spend enough time with the types who build their own homes or does this number seem a little high to you all?
