The National Broadcasting System's User Survey Form 1, 1975

This data set is derived from the “The National Broadcasting System's User Survey Form 1, 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 Monday the 21st of April, and the questions concern the days Saturday the 19th and Sunday the 20th of April.

本数据集源自挪威广播公司（Norwegian Broadcasting Corporation, NRK）委托挪威统计总局（Statistics Norway, SSB）于1975年开展的《全国广播系统用户调查问卷表1》。1975年的此项调查是挪威统计总局受挪威广播公司委托开展的年度听众与观众调查之一。1978年至1985年间，研究团队开展了多项专项调查，而综合性调查仅在1980年与1983年进行。自1985年起，正式启用每年开展三次综合性调查的新方案。

与此前的综合性调查一致，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或收看特定广播电视节目的人群占比，以及听众、观众按性别、年龄、教育程度、职业等背景特征划分的分布情况。同时收集相关数据，包括完全或部分收看/收听某一节目受众的人数，以及在该节目播出前后开始或终止收听广播、收看电视的受众人数。1975年的调查中还设置了多项专项议题，涵盖常规节目播出时段调整、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便利性等内容。

本次调查共设计7类问卷。每份问卷对应1个或2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。受访对象对应的问卷类型在抽样环节即已确定，以此确保每个节目播出日均能获取规模相近的受访样本量。

本次调查周期为4月19日（周六）至4月25日（周五）。本数据文件包含4月21日（周一）开展的访谈数据，所涉问题对应4月19日（周六）与4月20日（周日）的节目内容。
