It has for a long time. I'm technically part of the Baby Boom, but when people talk about "The Baby Boomers" they mean the first ten years. Its always obvious. Those of us in the second ten years are not similar. I find people group well by decade, starting in mid-decade: 1945-55, 1955-65, 1965-75, etc.
