Each full return of an occupation, as “Farmer-general farm,” is called an “occupational designation.” Each occupational designation given in the “List of Occupations” (Form 8-3000) is divided into two parts or columns, corresponding with columns 18 and 19 of the population schedule. In the first column the occupation of the person is given, and in the second the industry or establishment in which the person works. Preceding each occupational designation is a “punch symbol” composed of four figures. The first two figures in each entire symbol stand for the occupation of the person, and are called the “occupation symbol;” the last two figures stand for the industry or business in which the person is employed, and are called the “industry symbol.” For example, the symbol for “Cashier-bank” is 10-6-0-x. The “10-6” stands for “Cashier,” the “0-x” for “bank.”
