Omnibus September [South Africa], 1995 (M874V1)

ABSTRACT: An omnibus survey is done quarterly and its purpose is to give clients an opportunity to participate in a national survey at low cost. A number of clients’ questions are combined into one questionnaire. This questionnaire is usually administered to probability sample of 2 200 respondents in the whole country (South Africa). The 1995 February omnibus consisted of two separate samples of 2 200 each – one sample having a blue questionnaire and the other sample having a green questionnaire. The September 1995 omnibus survey was undertaken over the period 04 September to 06 October 1995. The data from this survey was available in December 1995. The fieldwork was done on a countrywide basis including all nine provinces. Interviewers specifically trained in personal interviewing collected the data. The respondents were scientifically selected, and interviewed at home. The interviews were conducted after hours to ensure that the scientifically drawn person was present. If the drawn person was not home during the first visit, but was available during the fieldwork period, an appointment was made and the person concerned revisited. If nobody in the household qualified, or was available during the fieldwork period, the household was substituted. The questions in the questionnaire were printed in both English and Afrikaans. During training these were translated into he relevant languages of the Black fieldwork areas. Interviews were conducted in the respondent’s choice of language. The respondent also had to be part of the scientifically drawn household, and be available during the fieldwork period. Substitution of the visiting point was only allowed for specified reasons.

摘要：本综合调查（omnibus survey）为季度性项目，旨在为客户提供以低成本参与全国性调查的渠道。调研团队将多家客户的调研问题整合至同一份问卷中。该问卷通常面向南非全国范围内由2200名受访者组成的概率抽样（probability sample）群体开展调查。1995年2月的综合调查包含两个独立的2200人样本组，分别使用蓝色问卷与绿色问卷。1995年9月的综合调查实施周期为1995年9月4日至10月6日，本次调查的相关数据于1995年12月对外公开。实地调查覆盖全国所有九个省份，数据由经过个人访谈专项培训的访员采集。受访者经科学抽样选取，并于家中接受访谈。为确保抽中的受访者在家中，访谈均在下班后进行。若首次访问时抽中的受访者不在家，但在实地调查周期内可接受访谈，则将预约后再次回访该受访者。若住户内无人符合受访资格或在实地调查周期内无法受访，则替换该住户。问卷同时以英语（English）与南非荷兰语（Afrikaans）印制，培训期间问卷会被翻译为黑人受访区域的相关本土语言，访谈将以受访者自选的语言进行。受访者需为科学抽样选定住户中的成员，且在实地调查周期内可接受访谈。仅在指定情形下，方可替换受访点位。
