The National Broadcasting System's User Survey, Form 7, 1975

This data set is derived from the “The National Broadcasting System's User Survey, Form 7, 1975” that was conducted by Statistics Norway (SSB) commissioned by the Norwegian Broadcasting Corporation (NRK). The survey from 1975 was one of SSB's annual listener and viewer surveys on behalf of NRK. Several special surveys were conducted in the period 1978 to 1985, while surveys of a more general character only were conducted in 1980 and 1983. A new arrangement with three general surveys per year was put to use from 1985.

The main purpose of the 1975 survey, like the preceding general surveys, was to estimate the share of the country's adult population that followed certain program posts on the radio and television in the course of particular survey period, and how the listeners and viewers were divided by background characteristics such as gender, age, education and professions etc. Information about how many that followed each program post entirely or partially and how many that started or ended their radio listening or television viewing in connection to the program post. Some questions that concern special topics were asked in the 1975 survey. This concerned among other things questions about changed broadcasting times for regular program posts, people's circadian rhythm, evaluation of the news coverage in different media and the possibilities for listening to the radio and watching television during the Easter holiday.

7 types of forms were prepared for this survey. Each form contained questions concerning programs for one or two particular program days (the last or the two last days before the day of the interview). What type of form each person was to be interviewed with was decided in connection to the sample selection. This was done in a way that one for each program day could obtain information from a similar number of persons.

The survey period was the week Saturday the 19th to Friday the 25th of April. This data file contains data for the interviews conducted Saturday the 26th of April, and the questions concern Friday the 25th of April.

本数据集源自挪威统计社（Statistics Norway, SSB）受挪威广播公司（Norwegian Broadcasting Corporation, NRK）委托开展的《1975年全国广播系统用户调查第7号表格》。1975年的本次调查，是SSB代表NRK执行的年度听众与观众调查项目之一。1978年至1985年间，项目组开展了多轮专项调查；而通用性质的全国调查仅在1980年与1983年进行。1985年起，正式启用每年开展三轮通用调查的新方案。

与此前的通用调查一致，1975年本次调查的核心目标为：估算该国成年人口中，在特定调查周期内收听、收看指定广播电视节目单元的人群占比，以及听众与观众在性别、年龄、教育程度、职业等背景特征上的分布情况。此外，调查还收集了完全或部分收看收听某一节目单元的受众规模，以及在该节目单元播出前后开始或终止广播电视收听收看行为的人群数据。1975年的调查还设置了专项议题模块，涉及常规节目单元播出时段调整、民众昼夜节律、不同媒体的新闻报道评价，以及复活节假期期间收听广播与收看电视的可行性等内容。

本次调查共设计7类问卷表。每份问卷表对应一个或两个特定节目播出日（即访谈日前一日，或访谈日前两日）的节目相关问题。受访对象匹配的问卷类型，将在抽样阶段确定，以确保每个节目播出日均能获取到数量相近的受访样本。

本次调查周期为4月19日（周六）至4月25日（周五）。本数据集包含4月26日（周六）开展的访谈数据，对应的受访节目单元信息为4月25日（周五）播出的内容。
