Letter from John Pullinger to Mr. Frank Field, dated 14 January 2004: The National Statistician has been asked to reply to your request for information on previous and subsequent births of mothers who had a birth registered without a father's name on the birth certificate (a sole registration) in each of the last 30 years. In particular you asked for information on (a) the social class and (b) the mother's age at her first live birth, and for information on how many of subsequent sole registered births the mother had. I am replying in the National Statistician's absence. (147176) Information is readily available, from birth registration records, on sole registration births by age of mother. However under the Population (statistics) Acts 1938 and 1960, information on birth order (that is whether a birth is a first birth, second birth etc.) is not collected at birth registration for women who are not married to the father of the child. Table 1, attached, provides information on the number of sole registrations by age of mother in each of the last 30 years (1973–2002). Similarly only limited information is readily available by social class from birth registration records. Social class of mother and father first became available separately from 1986. Only 10 per cent. of births are coded for social class and for around two thirds of sole registrations there is insufficient occupation data to assign a social class. Table 2 provides a summary of the readily available information on social class for sole registered births, 1986 to 2001. In 2001 the National Statistics Socio-Economic Classification was introduced, replacing social class, and from 2002 data are not available by social class. To provide information on age at first live birth and on any subsequent sole registration requires successive birth records to be linked together. This can only be done using the ONS Longitudinal Study, a one per cent. sample of the population in which, since 1971, census records and vital events have been linked together. Extracting this information cannot be done in the time available to answer this Parliamentary Question. I will write to you again in two weeks to let you know whether the information available from this study is of sufficient quality to answer your question. You should note that, as there is currently only 30 years of birth registration records in the study, only a small proportion of women in the sample have a complete birth history that allows identification of sole registrations. It is therefore very unlikely that the last part of your question (on the number of subsequent sole registered births) can yet be answered reliably.
