Note 218 — CRIMINALITY. (continued 2)

Before beginning, the following remark must be made. We shall give, as far as possible, the percentages of criminals born of illegitimate unions together with the percentages of illegitimate births in general. We shall see that with some exceptions, even so, the percentage for criminals is much greater than that for the population in general. However, to make the comparisons exact it is necessary to know the percentage of illegitimate persons among the population of an age to commit crime, and not among the newly born. This percentage is very much less, because, first, the mortality among illegitimate children is especially great, second, because a considerable number are legitimated. In general the percentage of illegitimate persons among the adult population is unknown. From researches by Neumann (“Die jugendlichen Berliner unehelicher Herkunft”) and Spann (“Untersuchungen über die uneheliche Bevölkerung in Frankfurt a/M.”), it appears that 3.6 times fewer illegitimate children in proportion, than legitimate, reach the age of 20 years!218
