Note.— The proportions shown in this table of legitimate births to wives, and of illegitimate births to 
unmarried women, were derived from the foregoing tables, giving the women of each class living in 1871 
and the mean annual number of children born in and out of wedlock to mothers of several quinquennial 
ages in the two years 1871-72, the proportions being interpolated for each year of age. These proportions 
applied to the classes of married and unmarried women of the English life table population (so divided 
according to the Census of 1871) produced the numbers of legitimate and illegitimate children born 
annually to women of each age. The total births were obtained from the casting of the legitimate and 
illegitimate births, and the first column of this table was thus derived from a comparison of the total births 
with the total female population.
