That's factually untrue according to the National Survey of Sexual Health and Behavior[0]. The facts are[1] that the younger the age group the higher the condom usage is.
And while condom use has fallen a little since its height, it still remains significantly higher amongst the young than any older generation or group.
It's really hard to interpret that graph when you consider things like relationships and marriage, and that older people are probably more likely to be married.
