NCHS Data Brief

Many thanks to John Tanton for this National Center for Health Statistics Data Brief No. 21 for August 2009. As John points out, the opening paragraph makes quite a useful statement. It points out that “Age at first birth influences the total number of births that a woman might have in her life, which impacts the size, composition, and future growth of the population.”
