1921 Census of England and Wales, General Report with Appendices, Table 80 : " Relative Fertility by Age of Parent".

Note.—The inclusion of step-children with natural children vitiates the comparative value of the rates at the older ages and the women's rates are therefore not carried beyond age 54.
