The fresh new frequency away from very first births you to took place the latest 6th so you’re able to seventh day out of relationship-and you may, to some extent, including regarding eight month of wedding-try expanding also, however, only until within the 19ong subsequent cohorts, they diminished and you will stabilised at a consistent level more below one seen among 1960s relationship cohorts.
