asked the Secretary of State for Social Services what are the latest available neonatal, perinatal and infant mortality rates for East Anglia; and if he will provide a breakdown according to socio-economic groups.

The latest available neonatal, perinatal and infant mortality rates for East Anglia are for 1981:

	Per 1,000
Neonatal mortality rate*	5·7
Perinatal mortality rate†	10·4
Infant mortality rate*	9·9
* Per 1,000 live births.
† Per 1,000 total births.

Rates are not routinely available for socio-economic groups and could only be produced at disproportionate cost. Rates by social class for regional health authorities, 1980, were published in OPCS Monitor DH3 82/3 (July 1982).
