X. Class and location of activity (sector) in which occupation declared in question V (see codes; only write the name of the activity class (sector) if you don't find it in Code List 4)

Question X - Class and place of activity where the occupation declared in Question V was exercised.

The purpose of asking for class and place of activity is to ascertain the sector of economic activity in which the person exercised the occupation declared in Question V. Therefore, there should be a distinction between these items of information. For example, a bookkeeper may exercise his or her occupation at a cattle ranch, a coffee plantation, a stone quarry, a textile factory, a radio equipment store, a private school, a construction company, etc. Depending on the case, the class of activity to be recorded will be cattle breeding, coffee growing, rock extraction, textile manufacturing, electric equipment trade, private education, civil construction, etc. Likewise, a physician might practice medicine at a private clinic, a public hospital or a cookie factory. Depending on the [p. 38] case, the doctor will declare Private medical clinic, Public health care or food industry as his or her class of activity.
It should also be kept in mind that the intention is not to find out whether the respondent works at large company or a small establishment, or if he or she exercises a technical or administrative function, is a subordinate or in authority. Thus a waiter in a small cafe and the manager of a large restaurant work in the same class of activity: Work in hotels, bars, cafes, etc. Likewise, a stonemason, an accountant and a driver, all three working in a construction company, although having different functions, are occupied in the same sector of industry - civil construction - which is therefore the class of activity to be recorded for all of them.
After obtaining the respondent's answer, the enumerator will consult the list of codes found on the side left of the questionnaire (Code 4 for Question X), and will record the code corresponding to the class of activity. The enumerator should write out the information in full only if the declaration and respective code are not shown on the list.
The objective of asking where (the place) the respondent exercises the activity is to obtain information that will enable the correct specification of class of activity. For this reason, the responses should characterize the activity carried out by the establishment or other organization where the person exercised the occupation declared in Question V, and not the address of this establishment, institution or organization.
