The line chart compares the average number of children born to one woman in the UK and Kazakhstan from 1920 to 2019, while the table shows the average age of women when they had their first child over the same period. Overall, fertility rates in Kazakhstan experienced significant fluctuations, while those in the UK steadily declined. Meanwhile, the average age of first-time mothers increased consistently in both countries.
In terms of fertility rates, the UK showed a gradual decline throughout the century. The average number of children per woman decreased from 2.8 in 1920 to around 2 by 2019. On the other hand, Kazakhstan experienced dramatic changes. The number of children born per woman rose sharply to a peak of 5 in 1960 but dropped significantly to approximately 2.5 in 2019, aligning closely with the UK’s figures.
The average age of first-time mothers rose steadily in both countries over the century. In the UK, this figure increased from 26.5 years in 1920 to 28.9 years by 2019. Similarly, in Kazakhstan, women started having their first child at an average age of 24.2 in 1920, but this increased to 27.6 by 2019. Although the starting ages differed, the trends reveal a common pattern of delayed motherhood in both nations.
