§ Mr. Dorrell
[holding answer 25 July 1990]: The information requested on live births by birthweight is as follows:
England 1989 Birthweight Under 1,000 grammes 2,325 1,000–1,499 grammes 3,891 1,500–1,999 grammes 8,283
Birthweight 2,000–2,499 grammes 28,127 2,500 grammes and over 586,749 unstated birthweight 19,982
Information on gestation, type of care received and outcome are not included in birth registration data, but are being collected from 1988–89 in the maternity hospital episode system. Complete data for 1988–89, the first year of the system, are not available and the extent to which the incomplete data can be used to make reliable estimates is currently under consideration. Preliminary indications are that the percentage of live births by gestation are as follows:
Babies born alive by gestation 1988–89 England Number of weeks gestation Per cent. All 100 Under 28 1 28–32 1 33–36 5 37–40 70 41–42 19 Over 42 1 Unknown 4
