Some occupations have given the statistical Impression of borag intrinsically unhealthy, whereas tholr unfavorable mortality night arise from their particu lar localization, whereby the workers and their families share the higher deathrates which predominate in that locality. This fact may be a factor In certain industries only carried on in larger cities, and, though well distributed over the country, high mortality may be due, xut entirely to the industry itself, but to the urban conditions. Cases ora cited in England, where, if these facts ore overlooked, certain erroneous conclusions might be drawn. Conclusions drawn from a mrrey of tho general population show that higher death ratoe con be cor related with higher latitudes, housing facilities and ratio of unskilled work ers.
