Note 3027 — Chapter XXI · THE FORMS OF HUMAN MARRIAGE
Reading edition
Jacobs, in ‘Jour. Anthr. Inst.,’ vol. xv. p. 26. Mr. Jacobs thinks that English Jews marry their first cousins to the extent of 7·5 per cent. of all marriages, against a proportion of about 2 per cent. for England generally, as calculated by Professor G. H. Darwin. M. Stieda, in his ‘Eheschliessungen in Elsass-Lothringen’ (1872-1876), gives the proportion of consanguineous marriages among Jews as 23·02 per thousand, against 1·86 for Protestants, and 9·97 for Catholics (Jacobs, ‘Studies in Jewish Statistics,’ p. 53).
