In round numbers then: 50% of the criminals come from a corrupt environment, and only 10% from a good environment; 40% had left home before the age of 15; and further, 40 to 45% had alcoholic parents.[254]

The following figures deal with illegitimacy of birth among the prisoners in Norway.

During the years 1887–1891, out of 100 living births 7.33 were illegitimate,[256] while the mortality of natural children in the first year was 15.3% and that of children in general 9.5%.[257] Persons of illegitimate birth formed a much greater proportion of the prisoners than of the population in general.

In the years 1887–1891 there were 7.81 illegitimate children out of each 100 living births; 35.7% of the illegitimate children died in the first year as against 20.8% of children in general (1884–1893).[259] In Prussia also, then, the influence of illegitimacy upon criminality is very marked.
