The line chart illustrates the trend of women’s birth rate per 1000 individuals among 6 age groups in the Uk between 1973 and 2008.
Overall, the birth rate declined in most of the surveyed age brackets except for the 30-35 and 35-39 ones, women in the age of 20-29 showed the highest natality of all ages.
In 1973, It is apparent the number of women whose ages ranging from 25-29 giving birth was the highest at 140 out of 1000 people, this figure then underwent a stable fluctuation by around 10 units before eventually ending at 120 women per 1000 in 2008. Otherwise, followed after were the birth rate of women in the 20-25 and 30-35 age group at over 120 and around 70 per 1000 respectively in the first year of the period. While there existed a gradual fall to under 100 in the figure for women aged 20-25, the opposite was true for those whose ages were between 30-35 with the fertility rate rising up to over 80 per 1000 within the same period.
Looking at the remaining features, women who were 40 and over had the lowest birth rate through all the years and saw a gradual decline from 20 in 1973 to roughly 17 per 1000 people in 2008. 40 and 60 women out of 1000 giving birth when they were 35-39 and under 20 respectively, these two objects shared the same figure at approximately 48 per 1000 individuals in 1998 before a sudden rise led the natality of woman aged 35-39 to over 60 per 1000 in 2008 and a stable decline to 90 in that of those aged under 20 within the same year.
