<span class="h2">7.6 Battery IV. Characteristics of the economic unit</span>
<br />The purpose of this battery of questions is to identify some important characteristics of the economic units, taking as a starting point the establishment in which the people who are employed perform their main job. Some of these characteristics are: name, proprietary sector, type of activity to which it is dedicated, the way in which it operates (whether or not it is registered under the Law of Corporations, in the case of private companies and businesses, or the way in which the public administration of this country operates), availability of premises and accounting records, as well as the geographic level in which it performs, in the case of private companies and businesses.</p>
<p><span class="em">Question 4</span>
<br />This question is asked to employed persons, in order to find out if the economic unit for which they work has a name.
<br />[Omitted figure]</p>
<p><span class="ital">Name of the economic unit</span>. The trade name, business name or name with which a company, institution or business advertises itself.</p>
<p><span class="em">Question 4a</span>
<br />This question is asked to employed persons to know the economic activities performed in the economic units for which they work in their main job, in order to classify them by economic activity sector.</p>
<p>[Omitted figure]</p>
<p>Conceptual clarifications:
<br /><span class="ital">Economic activity. </span>The set of actions performed by an economic unit for the fundamental purpose of producing marketable good and services in the market to generate monetary or in-kind income.
<br /><span class="ital">Economic activity sector.</span> Classification of the economic activities, according to the type of good or service the economic units generate.</p>
<p>Instructions:
<br />In describing the main activities to which the economic unit is dedicated, do not record unnecessary information, therefore keep in mind the following general guidelines:</p>
<div class="i1">- If an economic unit is dedicated, as a main activity, to something other than commerce: agricultural or industrial production, extraction, provision of personal services, health services, etc., when describing the activities do not indicate that one of these consists of selling their goods and services.<br /><br />[Omitted table]</div><div class="i1">- If an economic unit is dedicated to the sale of food, indicate whether it prepares and serves, or only prepares, and the type of foods involved: sweet potato, meats, churros, corn-on-the-cob, natural juices, tacos. It is unnecessary that you specify the type of ingredients used in their preparation and the place where they are cooked or served (the latter information is the subject of another question).<br />- Once the main activity to which the economic unit is dedicated is identified, describe it in detail. Below are the essential elements you should include in the information you record in this question to guaranty its correct classification:<br /><br />[Omitted table]</div><p>[Omitted table]</p>

<div class="i1">- Identification of the activity to which the economic unit is dedicated. In order to obtain the information, cite the name of the company or business recorded in the preceding question. You may ask the question in the following way:<br />- What type of work does <span class="lang">"Textilera San Marcos"</span>, for which you worked last week, do?<br />- What type of work did Mr. Emilio do last week?</div><p>To further clarify the information, describe in detail the type of activity. To do this, ask additional questions, such as the following:</p>
<div class="i1">- Does the construction company build complete houses (from foundation to finishing) or just the structural work?<br />- In addition to demolishing buildings, does it also build them?<br />- What types of installations does it complete in the buildings: air conditioning, screens for bathrooms, anti-theft devices, electricity, gas piping, plumbing, floors, agricultural irrigation systems?<br />- If an informant reports that the economic unit for which they work performs more than one activity, ask what is the main one and underline it. Respect their response. For example, selling groceries, preparing and selling food, or collecting medicinal herbs and providing medical care; ask which is the most important activity. Record both, but underline the one reported as main.<br />- When an economic unit's activities vary throughout the year, for example: in one season it is dedicated to agricultural activities and in another, building homes; to selling ice cream in spring and summer and selling flags in September and toys in December. Record the activities performed during the reference period.<br />- Sequence to follow. Regardless of the information recorded, continue with question 4b.</div>
