Of Criminal Statistics it may be said in the first place, that they act as an annual register for tabulating the amount of danger to which society is exposed by the nefarious operations of lawless persons.  By these statistics we are informed of the number of crimes committed during the course of the year so far as they are reported to the police.  We are informed of the number of persons brought to trial for the perpetration of these crimes; of the nature of the offences with which incriminated persons are charged, and of the length of sentence imposed on those who are sent to prison.  The age, the degree of instruction, and the occupations of prisoners are also tabulated.  A record is also kept of the number of times a man has been committed to prison, and of the manner in which he has conducted himself while in confinement.

One important point must be mentioned on which criminal statistics are almost entirely silent.  The great sources of crime are the personal, the social, and the economic conditions of the individuals who commit it.  Criminal statistics, to be exhaustive, ought to include not only the amount of crime and the degrees of punishment awarded to offenders; these statistics should also, as far as practicable, take cognisance of the sources from which crime undoubtedly springs.  In this respect, our information, so far as it comes to us through ordinary channels, is lamentably deficient.  It is confined to data respecting the age, sex, and occupation of the offender.  These data are very interesting, and very useful, as affording a glimpse of the sources from which the dark river of delinquency takes its rise.  But they are too meagre and fragmentary.  They require to be completed by the personal and social history of the criminal.  Crime is not necessarily a disease, but it resembles disease in this respect, that it will be impossible to wipe it out till an accurate diagnosis has been made of the causes which produce it.  To punish crime is all very well; but punishment is not an absolute remedy; its deterrent action is limited, and other methods besides punishment must be adopted if society wishes to gain the mastery over the criminal population.  What those methods should be can only be ascertained after the most searching preliminary inquiries into the main factors of crime.  It ought, therefore, to be a weighty part of the business of criminal statistics to offer as full information as possible, not only respecting crimes and punishments, but much more respecting criminals.  Every criminal has a life history; that history is very frequently the explanation of his sinister career; it ought, therefore, to be tabulated, so that it may be seen how far his descent and his surroundings have contributed to make him what he is.  In the case of children sent to Reformatory Schools, the previous history of the child is always tabulated.  Enquiries are made and registered respecting the parents of the child; what country they belong to, what sort of character
