Conception data combine information from registrations of births and notifications of legal abortions occurring in England and Wales for women who are usually resident there. Conception statistics include pregnancies that result in:
- One or more live, or stillbirths (a maternity)
- A legal abortion under the Abortion Act 1967
They do not include miscarriages or illegal abortions.
The date of conception is estimated using recorded gestation for abortions and stillbirths, and assuming 38 weeks gestation for live births. A woman’s age at conception is calculated as the number of complete years between her date of birth and the date she conceived.
