ABSTRACT
CLASS and Occupation.—At the census of 1841 and more completely at the subsequent census enumerations, each individual was classified under his principal occupation on the census day, with distinction of age and sex. The distinction of age is important, as it enables us to compare the number living in each well-defined occupation with the number who are registered as dying at the corresponding ages, and thus to determine the influence of occupation on health and life; and also because it enables us to determine whether those engaged in any particular occupation are children, or young or old adults, which information has important social bearings.
