Items 15 - 18 are only for "employed" and "unemployed"
15. Occupation
____
Line No. 15.-Occupation
Ask this question only for "Employed" or "Unemployed".
Write down in this space the word or expression that describes clearly the nature of the job that a person did during the reference period (March 1963). When a person has had more than one job in this period ask and write down the principle one, or that is the one which reported the largest wages.
Write down words and definitions that define the nature of the job in a precise form; for example: farm worker, carpenter's aid, street salesperson, civil engineer, lawyer, cashier, nurse, sanitary inspector, carpenter, mason, teacher.
Avoid the use of generic terms such as: worker, aid, owner, day laborer, etc., which say nothing about nature or class of work that a person did during the period of reference, which is what is wanted.
When it concerns "Unemployed", ask and write down the last occupation the person had, it does not matter how long ago it was.
Keep in mind that here what you should write down is the occupation and not profession. Of course, it can happen, and it is very frequent, that both (occupation and profession) coincide; but also it can happen that they do not; for example: it is common that doctors, engineers, lawyers, etc. work in the same profession; nevertheless also it is frequent that a Doctor is the Administrator of a hospital, or an Engineer the Manager of a company; cases in which the occupation of a person does not coincide with their profession.
[p. 52]
It is evident that in the last two examples, the occupation of the doctor is "Administrator" and that of the engineer is "Manager". Because of this is, precisely, why the enumerator should ask for the occupation, and in the case of professionals, insist more from the person to determine if the profession or occupation coincides, that is to say, if the doctor works as a doctor, the lawyer as a lawyer, engineer as engineer, etc.
