The number of women who are choosing to wait until they are older to start their families has been on the rise over the past three and a half decades.
The average age of first-time mothers has increased by 3.6 years over last 36 years, from the age of 21.4 years in 1970 to the age of 25 in 2006.
The researchers were interested in pinning down the average age of first-time mothers since the age of a woman’s first birth has a bearing on the total number of births she may have within her lifetime.
In turn, this has an impact on family size and future increase in the overall population.
In addition, a mother’s age, whether younger or older has an effect on outcomes of births including birth weight, multiple births, and birth defects.
The report showed that the most dramatic increases in the average age at first birth were seen during the 1970s and 1980s.
In addition, the largest role played in the overall increased average age of new mothers was observed to be in the age range of 35 years and over.
