Many baby boomers hit an important milestone last year. Those earliest boomers born at the start of 1946 turned 70, and are now turning that age at a rate of 10,000 people per day for the next 18 years. The Census Bureau also indicates that for the first time in history the aging populations of 65 and older will double that of children (ages 5 and under) worldwide within the next 3 years.
