Live and still births registration data for England and Wales include every death registered. Live birth records contain details such as date of birth, sex, birth weight, place of birth, and parental information. Still birth, defined as babies born dead after 24 complete weeks of pregnancy, contains details such as cause of deaths, birth weight, and parental information.

SAHSU holds a data sharing agreement with the ONS and has access to a restricted subset of variables from the full dataset.

The dataset may be internally linkable with SAHSU's environmental datasets, including air pollution and green space.
