Interviewer instructions
<span class="h1">6. Sociodemographic questionnaire</span></p>

<p>The central goal of the sociodemographic questionnaire is to record, as its name states, the main sociodemographic characteristics of the residents of selected homes, such as sex, age, place of birth, education, marital status of the people and to identify the population 12 years of age or older to whom the occupation and employment survey should be applied (the purpose of which is to identify information in the occupational characteristics of the population). Additionally, it permits precise control of the field work, as shown below.</p>

<p>Taking into consideration that the ENOE is a survey visiting the selected residence up to five times, once each trimester (the first visit is made to compile the required information and the remaining four visits are made to update this information), the questionnaire design is such that most of the headings, especially those related to identification data, include up to five fields to record information referring to the same topic.</p>

<p>In general terms, the sociodemographic 1uestionnaire is divided into two larger sections which we will call cover page and back. The content and completion instructions are described below, first, of the cover page and then those referring to the back</p>

<p><span class="em">Cover page</span></p>

<p>[Omitted figure - image of the first page from the sociodemographic questionnaire]</p>

<p>Most of this section contains information that allows the selected homes to be located, from a geographical and processing perspective, and provides operative control of the interview, but also allows the basis of the information that will be obtained in relation to the residents of the home, the number of households included within them and the availability of the domestic employees.</p>

<p><span class="h2">6.1 Section I. Identification data</span>
<br />The objective of this section is to geographically reference the selected home.</p>

<p><span class="em">Instructions:</span><div class="i1">- Most of the information shall be transcribed from the list of selected homes (mnv-07) with the exception of data referring to the headings questionnaire of questionnaires, phone number, household no. and household moved. The identification data shall only be recorded the first time you conduct the interview in the selected home. The transcription of this data must be faithful in order to avoid serious problems in the subsequent phases.<br /><br />[Omitted figure - Identification data]<br /><br />- Write the data pertinent to the headings questionnaire of questionnaires, phone number, household no. and household moved based on the criteria stated below.</div><span class="em">Questionnaire of questionnaires</span>
<br />This heading is used to enter the number of questionnaires used to obtain the information from each household. Fill out this heading. Until you have finished the interview.</p>

<p>[Omitted figure]</p>

<p>To avoid overlap, whenever you use more than one questionnaire, be sure that you enter all identification data on each of them.</p>

<p><span class="em">Telephone number</span>
<br />This data can be extremely useful to verify or supplement the information compiled during the interview, set appointments (interview date and time) when it has been difficult to contact the informant; but if they refuse to provide them, do not insist, leave the space blank. Regardless of the response to this request, explain that this information will only be used in the cases described.</p>

<p>[Omitted figure]</p>

<p><span class="em">Household number</span>
<br />To determine the number you should enter in this heading, first check how many households or groups of people are in the home. To do this, consult the information in question 3 of section V Residents of the home and household identification, and also take the following criteria into consideration:</p>

<p>[Omitted figure]</p>

<p><span class="em">Instructions:</span><div class="i1">- Homes with a single household. If only one household resides in the home, in this heading you should always enter the number one, regardless of whether it is a household different from the one registered in a previous visit.<br />- Homes with two or more households. Identification of household number one. If more than one household resides in the home, assign one of them number one and the rest a progressive number. The household assigned number one shall be at the discretion of the informant; if they do not know which to assign this number, tell them that it should be the household to which the owner or person responsible for the home belongs.<br />- The number you assign to the other household(s) have no special criteria, so you can assign the numbers arbitrarily, as the only purpose is to distinguish them from each other; but, you should use one sociodemographic questionnaire for each household.<br />- Homes in which a resident could not be contacted. If despite your efforts to establish contact with any of the residents of a home, you cannot do so; consider, for the purpose of filling in the heading Household no., that there is only one household in that home, that is, enter the code number one.</div><span class="em">Household moved</span>
<br />Household moved. The replacement of one household by another in the course of the second to fifth visit to the home.</p>

<p><span class="em">Conceptual clarifications:</span>
<br />This heading identifies whether the household(s) recorded as residents of the home in the first interview are or are not the same from one interview to another throughout the five trimesters the home remains in the sampling.</p>

<p>A household is considered to have moved from the home if all the members of the household left, and only if said household was replaced by another. From an operational perspective, the existence of a household moved should only be entered if an interview has been conducted with the household that replaced the previous one.</p>

<p>If the new household refuses to provide the information, the number entered in the field Household moved on the questionnaire of the previous household should not be changed under any circumstances until the replacement becomes effective; therefore, only for operational purposes you should continue using the same questionnaire for the household that was there to enter the results of the refusal.</p>

<p>A household is also considered to have moved in cases such as the following:</p>
<div class="i1">1. When no member 12 years of age or older obtained in a previous interview has remained, even if members of that household under 12 years of age have remained in the home, and where they can be cared for by other person(s) 12 years of age or older, or not.<br /><br />First interview<br /><br />[Omitted table]<br /><br />Second interview<br /><br />[Omitted table]<br /><br /><span class="pg">[p.77]</span><br /><br />2. When the employers have returned to the home, in the case of homes inhabited by domestic servants, who had initially been obtained as the sole household residing in the home.<br /><br />First interview (Household of domestic servants)<br /><br />[Omitted table]<br /><br />Fourth interview<br /><br />[Omitted table]<br /><br />3. If at least one of the members 12 years old or older returns after it was uninhabited, it is not entered as a household moved, as the household was not replaced by another. If other people have arrived with the person(s) who returned, record the former as new members of the original household.</div><p>Do not change the code entered in household moved. Limit yourself to updating the information.</p>

<p>To facilitate the operational work, use the same questionnaire that had been used before the home was abandoned.</p>

<p>Example:</p>

<p>First interview
<br />[Omitted table]</p>

<p>Second interview
<br />[Omitted table]</p>

<p>Fourth interview
<br />[Omitted table]</p>
<div class="i1">4. When you detect that information was being collected in the wrong home. Follow these instructions once you conduct the interview in the correct home; if you are not able to do so, do not change the data recorded in household moved, and in the heading Result of no interview, enter the code based on the result.</div><p>Example:</p>

<p>[Omitted table]</p>

<p>Don't consider a household to have been replaced if at least one of the members 12 years old or older from the previous household remains in the home, due to the simple fact that members have been added who are older than the members of the original household; in this case consider the new residents simply as new members.</p>

<p>Example:</p>

<p>[Omitted table]</p>

<p>Fourth interview
<br />[Omitted table]</p>

<p><span class="em">Instructions:</span><div class="i1">-In the first interview, enter the code zero for each household; this should not be changed until it is effectively replaced by another household.</div><p>To facilitate the explanation of how to report households moved, in the example shown below, the surnames of the supposed households are included, although in practice you will have to review the information entered in the first five questions as a whole in order to determine if a household has moved, considering that when the information is obtained, the people's surnames are not entered.</p>

<p><span class="em">Homes with one household</span>
<br />Household status:</p>

<p>1. The household moved and was replaced</p>

<p>How to proceed?
<br />In this case three situations may be present:</p>
<div class="i1">1. A household obtained in a previous interview has moved and another is found in its place.<br />2. People older than 12 years of age have left the home and only the younger children remain.<br />3. In a previous interview the household of a domestic servant was recorded as the only household, but the employer's household has returned.</div><p>To report the case as a household moved, do the following:</p>
<div class="i1">Use a new questionnaire to obtain the new household's information.<br />Transcribe all identification data from the previous questionnaire to the new questionnaire, except data for the heading household moved.<br />In household moved, enter the code 1, 2, 3, or 4 based on the number of household changes in the home.<br />Start the interview.</div><p>In the case of the household that has moved due to the departure of members 12 years of age or older and in the case of employers (of domestic servants) who have returned to the home, in addition to the aforementioned criteria, do the following: include those less than 12 years of age as members of the new household; and in the case of domestic servant(s), include them on the same questionnaire for the new household, at the end of the list of members of the household.</p>
<div class="i1">Cancel the questionnaire for the household that has moved as follows:</div><div class="i2">- On the cover page, using a blue pen, draw two diagonal parallel lines and between them write the phrase: "The household moved".<br />- Staple the voided questionnaire to the new one, so that the back of the new form is in front, to facilitate its subsequent review.</div><div class="i1">If the only household that resided in the home left, but it was replaced by two or more households, do the following: as one of the new households must replace the one that left, assign it code one to indicate that it has replaced the one that left, and for the other households, as they are not replacing any other household and are being entered for the first time, under the heading household, enter the corresponding consecutive number and in the household moved enter zero, as it will be the first time they are obtained.</div><p>Example:</p>

<p>[Omitted table]</p>

<p>2. The interview could not be conducted in the first trimester
<br />If you are not able to obtain the information in the first interview for any reason, enter the code 1 in household number and the code zero in household moved. These codes shall remain even until you are able to conduct the interview in the household. In these cases, use the same sociodemographic questionnaire to collect the information.</p>

<p>If in any subsequent interview you find that the home is now inhabited, use the same questionnaire to collect the information.</p>

<p>Example:</p>

<p>[Omitted figure]</p>

<p>3. The home is uninhabited
<br />If in an interview other than the first, you find that the household entered previously has abandoned the home and it is now uninhabited, proceed as follows:</p>
<div class="i1">- Do not change any data or cancel the questionnaire as long as the home remains uninhabited.<br />- Enter the code 06 under the heading result of the interview. Assign the same code in each trimester, as long as it remains uninhabited.<br />- If the home again becomes inhabited by a different household than the one obtained previously, treat it as a household moved, that is, proceed as indicated in point 1.</div><p>This same criterion applies if only children less than 12 years old have remained in the home, as they are inadequate informants.</p>

<p>Example:
<br />[Omitted table]</p>

<p>4. The household that had moved has returned
<br />If when you go back to the selected home you find that it is again inhabited and when conducting the interview you detect that it is the same household as that obtained in another interview, do not treat it as a household moved, as the household was not replaced by another; therefore the code entered in the heading household moved should not be changed.</p>

<p>Now, in order to facilitate the work of updating the information, you should use the same questionnaire.</p>

<p>Example:
<br />[Omitted table]</p>

<p>4. The household that had moved has returned
<br />If a household returns after another has inhabited the home, treat it as a household moved. That is, obtain the information on another questionnaire.</p>

<p>Example:
<br />[Omitted table]</p>

<p><span class="em">Homes with two or more households</span>
<br />The procedure to report cases of a household that has moved when two or more households reside in the selected home is similar to that for cases in which only one household is in residence, except in the following situations:</p>

<p><span class="em">Household status</span>
<br />1. One or more households left, but there was another in their place</p>

<p>How to proceed?
<br />If, when conducting the interview, you detect that one or more of the households have moved but were replaced, do the following:</p>
<div class="i1">- Fill out a questionnaire for each new household.<br />- In the heading household no., enter the same code as the replaced household.<br />- In the heading household moved, enter the corresponding progressive number.<br />- Cancel the questionnaire of the household(s) that left.</div><p>Example:
<br />[Omitted table]</p>

<p>2. One or more households left and they were not replaced
<br />If, when conducting the interview, you find that there are fewer households in the home than those obtained in the previous interview, do the following:</p>

<p>Cancel the questionnaire for the household that has moved as follows:</p>
<div class="i1">- On the cover page, using a blue pen, draw two diagonal parallel lines and between them write the phrase: "the household moved".<br />- In result of the interview, enter the code 14. As you can see later in section ii result of the interview, this is an independent code from the typology considered in the code list, and indicates that the home remains inhabited, although the household in question has left.<br />- If the household that moved was number 1, update the data in the section v residents of the home and identification of households in household questionnaire 2. no additional explanation will be necessary, taking into consideration that the codes entered in the heading household moved and result of the interview in the questionnaire of the household that left, will be sufficient to understand why that questionnaire was updated.<br /><br />Example:<br />[Omitted table]<br /><br />- Continue with the normal interview in the case of the households that have remained in the home.</div><p>3. One or more households left, but were replaced in subsequent interviews
<br />If when you go back to a home in which the number of resident households reported had previously decreased, you detect that the number has again increased, record the new households as follows:</p>
<div class="i1">- In household number, enter the consecutive number that corresponds to each of them in relation to the household(s) that still reside in the home, and in relation to the household that is being replaced.<br />- In household moved enter the consecutive number corresponding to each household according to the number of household replacements that have occurred in the home for that household in particular.<br />- In result of the interview for the new household, enter the code 00; for the household(s) that were not replaced, enter the code 14. This code is only used the first time you detect that the household in question is no longer residing in the home, as long as other households remain in residence.<br />- Cancel the questionnaire(s) of the households that left, according to the stated guidelines.</div><p>Example:
<br />[Omitted table]</p>

<p>4. All the households left and none were replaced
<br />When you detect that in a previous interview the presence of two or more households was reported, but in the current interview you detect that the home is uninhabited, report the situation as follows:</p>
<div class="i1">- Do not change any data recorded in the headings household number, household moved, or cancel the sociodemographic questionnaires of the households that left, as long as the home remains uninhabited.<br />- In result of the interview of each household, enter the code 06 or that corresponding to type B or C. Assign the respective code in each trimester, as long as the home remains uninhabited.<br />- If in a subsequent interview you detect that home again becomes inhabited by one or more different households, in household moved, enter the corresponding code according to the number of households replaced in the home for that household, and in result of the interview enter the code 14 for the household that was not replaced.<br />- Cancel the sociodemographic questionnaire of the household that left.</div><p>Example:
<br />[Omitted table]</p>

<p><span class="em">Special case</span>
<br />Treatment of the household that moved. If in an interview after the first one, when trying to update the information, the informant reports that the information obtained previously was purposely falsified and agrees to correct it in the current visit, as an exceptional case, treat it as a household that has moved in order to obtain the correct information.</p>

<p><span class="em">Joining or dividing households in the home</span>
<br />It is possible that during the second to fifth interviews you detect that the quantity of households in the home has increased or decreased in relation to the number originally recorded, because they decided to unite (join) or separate (divide).</p>

<p><span class="em">Conceptual clarifications:</span>
<br />Joining of households. Union of two or more households that had previously been obtained as independent. Consider them joined when the households begin to share grocery expenses.
<br />Dividing of households. Separation that occurs in a household (that had previously been obtained as a single one) to form two or more households. Consider them divided when the households no longer share grocery expenses.</p>

<p>Instructions:
<br />In the case of joining:</p>
<div class="i1">- Cancel the sociodemographic questionnaire of the household that became part of the other, as follows:</div><div class="i2">- Using a blue pen, draw two diagonal parallel lines and between them write the phrase: "household joined with household no. x".<br />- In result of the interview enter the code 14, since the home remains inhabited when you report that this household has joined.</div><div class="i1">- In the sociodemographic questionnaire of the remaining household, record the people from the household that disappears as new members.</div><p>When there is division of household(s):</p>
<div class="i1">- Remove the household of the people who now form other households, according to the criteria of section VIII, question 6. sociodemographic characteristics.<br />- Use a sociodemographic questionnaire for each household that was formed as a result of the separation.<br />- In the heading household number on each new sociodemographic questionnaire, enter the corresponding consecutive number according to the number of households in the home.<br />- In the heading household moved of each new sociodemographic questionnaire enter the code 0.</div><p>In the case of a wrong home:</p>

<p>Although it is uncommon, there is a possibility you will find that, due to error, the information was collected in the wrong home. Before making any correction, verify the situation. Compare the identification data on the list of homes with the physical location of the home. Remember that it is wrong to define the location of a home based on the name entered on the list of homes; if you consider it appropriate, ask for your supervisor's support.</p>

<p>If you find that you have effectively been completing the survey on the wrong home, do the following:</p>
<div class="i1">- Cancel the sociodemographic questionnaire of the mistaken home by drawing two diagonal parallel lines (with a blue pen) on the cover page and in the middle write down the phrase "wrong home".<br />- Use a new sociodemographic questionnaire to obtain the information for the correct home; transcribe to the new questionnaire all identification data except that referenced in the heading household moved. In this case, enter the code number one, that is, treat it as a household that has moved. Thus, this code shall indicate to the system that the household obtained previously no longer exists and that the current one has replaced it. Continue to conduct the interview as normal.<br />- When you have concluded the interview, staple the sociodemographic questionnaire of the wrong home to the one filled out for the correct home.</div>
