Overview

Live and stillbirth figures are collected through the births registration system and are published annually in packages on the Births Product Page. The packages present?statistics on live and still births occurring annually in England and Wales. Statistics for births in previous years are included to show trends in fertility.

The summary tables contain data for numbers of live births, fertility rates, percentage of births outside marriage, sex ratio, mean age of mother, area of usual residence of mother and mother's country of birth.

Detailed statistics on births are published as a series of packages following the release of final summary data. These packages cover birth counts and rates tabulated by among other attributes, parents' age, occurrence within/outside marriage, multiple births, mother's area of residence and country of birth, place of birth, and father's social class. Information on the sex ratio of births and birthweight is also included.

In addition to monitoring fertility trends, live birth statistics by sex are used in the calculation of the mid-year population estimates produced by the Office for National Statistics.

Stillbirth figures are used to calculate the stillbirth rate and the perinatal mortality rate.

Technical Data

Data Collection

Data on live births are collected through the births registration system. This is a service carried out by the Local Registration Service in partnership with the General Register Office (GRO) in Southport. Every registrar of births and deaths is required to secure the prompt registration of births occurring within the sub-district covered. Registration of a birth is legally required within 42 days of its occurrence.? Some registration districts now use the Registration online (RON) system while others currently use the Registration Service Software (RSS).

Details Collected

Most of the information, for both live and stillbirths, is supplied to registrars by one or both parents. Informants are required to provide certain information treated as confidential, under the provisions of the Population Statistics Act. Details provided by the parents include date of birth, place of birth, sex, birthplace of parents, mother¡¯s usual address and occupation.

Details required under the Population Statistics Act include mother¡¯s date of birth, father¡¯s date of birth (where his name is on the certificate), and for births within marriage: the date of marriage and numbers of previous live born and stillborn children. Other statistical information collected at registration includes the economic activity of the parents, such as industry and employment status, and whether the confinement resulted in a multiple birth. For live births, details of the birth weight are notified to the local health authority and are then supplied to the registrar.

For stillbirths, details of cause of death, duration of pregnancy and weight of foetus are supplied on a certificate or notification by the doctor or midwife either present at the birth, or who examined the body.

For the latest live birth statistics see Live births on the National Statistics website.

Rates and Denominators

The population figures used to calculate fertility rates for England and Wales are the mid-year estimates of the resident population of England and Wales based on the 2001 Census of Population and updated each year.? Where fertility rates are published prior to the mid-year estimates are available, population projections are used for national level data. Further details about population estimates can be found at the National Statistics website.

Marital status estimates are used to calculate fertility rates within and outside marriage.

Data Quality

The accuracy of information contained in the draft birth entry is the responsibility of the informant(s) and in general this information is believed to be correct. Computerised internal consistency checks are applied to each record to eliminate, as far as possible, errors made in the supply and recording of information on births.? With the introduction of RON it has become possible to carry out some additional validation checks at the point of registration, for example, validation of address and postcode.

Under the Population Statistics Act certain data items are collected at the registration of a birth (detailed above). If any of these required data items is missing, an appropriate value is imputed. For further details on the imputation methodology see section 1.4 of the annual volume FM1 Birth statistics.

Since the dataset for the 2000 FM1 Birth statistics volume, a small number of very late registrations have been excluded each year from the official statistics. Inclusion of these very late registrations in the statistical dataset was found to have an adverse effect on the quality of infant mortality data when linked with the live birth data. The annual dataset now includes only those births occurring in the reference year, and late registrations of births occurring in the year previous to the reference year.

For full technical information see FM1 Birth statistics.
