2IntroductionEnumerators are the most important category of staff in the statistical data collection process. Why?They are in direct contact with respondents and thus have a great bearing on the quality of data collected and ultimately on the quality of statistical products coming out of the National Statistical Office.Their input can never be over emphasised in the evidence-based decision making process that is being implemented by/within the SADC member states.
3Duties of enumeratorsDuties of enumerators can be broadlyclassified into the following categories:Pre–enumeration dutiesDuring enumeration dutiesPost-enumeration duties
4Pre–enumeration duties Attend training courses, that is, training of enumerators’ workshopReceiving enumeration materials and equipment from the supervisorDevelop an enumeration schedule/itineraryBe familiar with the EA and the household/holding that he has been assigned to interviewChecks and amend the EA map where necessary, and inform the supervisors of any changes
5During enumeration duties The core of the enumerator’s task is to:locate (or select) his/her sample membersobtain interviews with themask questionsrecord answers as instructed andComplying with the requirements necessary for conducting a successful interview.
6Locating/selecting sample members To locate the respondent it is first necessary to construct a sampling frame, which may require field work itself – a process called listing.In some cases, enumerators are provided with random number tables and asked to select the sample.
7Obtaining an interview Arranging an interview is sometimes not as straightforward as it sounds; one has to consider the timing of the interview.If time is not considered, a lot of call backs will have to be done thus affecting the time allocated for the survey.Time can influence the accuracy of the data obtained.It is best practice to select a time that is convenient for the respondent and to follow the procedure as defined in the enumerator instructions manual.
8Asking questionsEnumerators are expected to:ask all applicable questions.ask them in the order given and with no more elucidation and probing than is explicitly allowed and,make no unauthorised variations in the wording of questions.In general, the aim is to attain uniformity inthe asking of questions and recording ofanswers.
9After recording all responses, the enumerator must: Recording responsesIn most interviews, enumerators have to record answers/responses given by respondents.Exceptions occur when questionnaires are left to be filled in by the respondent and are later on collected by the enumerator e.g. in household expenditure surveys.After recording all responses, the enumerator must:edit the questionnaire to check that all questions have been asked and all responses recorded.ensure that he/she has ringed/ticked the right codes andcheck that there are no inconsistencies between answers.
10Post enumeration duties ensure that enumerator checking is complete.ensure that all questionnaires and equipment are accounted for.hand over all questionnaires (filled, spoilt & blank) with other literature and materials used in the survey to the supervisor.write a brief field report.
11Equipment needed by an enumerator In order to carry out his/her job effectively, an enumeratorneeds a number of items including;questionnairesballpoint pensclip boardsletter of appointment and/or identificationwaterproof bag or containers in which to store questionnaires (used or unused) from becoming wet and untidyschedule of workEnumerator Instructions Manual for consulting in case he/she has forgotten some concept(s) or definition(s),a notebookmaps for recognition of EA boundaries
12Characteristics of a good enumerator HonestyIn the sense of not falsifying or fabricating responses.However, it should be noted that honesty and integritycannot be easily assessed at the recruitment stage butenumerators who are later found deficient on these scoresshould be quickly dismissed.InterestInterest in survey work is highly desirable. Errorsand poor quality work are much more likely if theenumerator is bored and regards the work asvalueless.
13Characteristics cont’d 3.Knowledge of the customs, traditions and language of the target populationThis helps in the interpretation of questions,answers, and furthermore, in the avoidance of wordsor phrases that will/can embarrass the respondent.4.AccuracyEnumerators should be accurate in their recording ofanswers, in the way they follow instructions, applydefinitions and carry out their administrative duties.
14Characteristics of enumerators cont’d 5.AdaptabilityIf the enumerator is likely to be employed on avariety of surveys, including different types ofquestions, subjects and respondents, he/she shouldbe a person who easily adapts to varyingcircumstances.6. Personality and temperamentThe enumerator’s personality should be neitherover-aggressive nor over-sociable. Pleasantness,politeness and a business-like manner is the idealcombination.
15Characteristics of enumerators cont’d 7. Educated to the appropriate levelThey should be educated to a level thatallows them to understand and followinstructions of the study.Self-sufficiency and independenceThe enumerator will be expected to workalone, at unusual hours and often inuncomfortable or remote surroundings.
16Rules for enumeratorsThe rules can be categorised as follows:Pre–enumeration rulesDuring enumeration rulesPost-enumeration rules
17Pre-enumeration rules He/she must know and follow the instructions manualAdhere to the dress code of the organisation that has engaged/employed you.
