According to National Statistics (ONS) estimates, women in England and Wales are likely to have children in life later and smaller families than previous generations.

ONS says that at the age of 18 in 2025, girls are likely to have an average of a child by an average of 35 years of age – unlike the generation of their mothers, which was an average of a child per woman by the age of 31 years.

They are also estimated to have an average of 1.52 children during their lifetime – 1.95 children for their mothers and 2.04 children for their grandmother.

New analysis For the first time ONS has discovered how the breeding level can change in future generations.

It sees a reproductive pattern with a generation pattern of its mothers for women born in 1978 – people born in 1951 are considered – and estimates for the generation of their daughters – people born in 2007 are considered, who became 18 years old this year.

This shows that people born in 1978 have a child until they reach 31 on an average. For the generation of their mothers, it took place up to the age of 26.

By advancing this trend in the future, ONS found that women born in 2007 are likely to have a baby average until they are 35 years old.

For girls born in 2025, it is estimated to be by the time they are 36 years old.

Kerry Gadsdon from ONS stated that the trend can be operated by “financial pressures and other life events such as partnership formation and going into your home generally later”.

This data also shows the largest average family size for women born in England and Wales over the last 100 years, for girls born in 1934 and 1935, who had an average of 2.42 children.

Estimates suggests that a steady decline began in the early 1980s – on average of 1.80 children born in 1990, 1.54 for those born in 2000, 1.52 for those born in 2007 – 1.52 – who are 18 years old this year – and 1.46 for girls born this year.

Most of their children born in 2007 have become 30 years old. In contrast, women born in the first few decades of the 20th century already had most of their children until they had reached the same age.

The latest analysis ONS comes months after published data which found The fertility rate in England and Wales fell to its lowest rate on records.

The ONS stated that only 591,072 infants were born in 2023, lower than any year since 1977 and a decline of over 14,000 last year.

research suggests In pregnancy, pregnancy increases the risk of complications during pregnancy and labor.

Research to suggest more women in the late 30s will also experience difficulties in conceiving compared to women in the late 20s or early 30s.
