However

, figures slightly escalated up to 3

at the end

of the duration.

In contrast

, the values in the UK escalated slightly during the

first

40 years from 2 to about 2.75, and dropped slightly to end up at below 2 in 2019. In the UK, the

first

child delivered at the average

age

of 26.5 in 1920, which had a significant upward trend up to 28.9 in 2019,

although
