By the end of the period, while the level of birth rate to people aged under 20 and 20 – 25 were 1.5 times lower than where they began, that of 40 and over decreased a half.
As for the other three age brackets, there was a slight rise in the birth rate of women who belong to the 30 to 35 age group, from 75 to 85 per thousand. Likewise, the birth rate of adults who aged 35 to 39 experienced a significant growth, stood at 40 thousands in 1973 and peaked at 65 thousands at the end of the period. Additionally, the predominant birth level record was people who were between 25 and 29 years old.
