Labour Force Survey 1978, 2.quarter

Statistics Norway has carried out official quarterly Labor Force Surveys (AKU) from 1 quarter 1972. The purpose is to provide the labor authorities and others with the occupational structure of population and development over time. The surveys will provide the basis and statistical material for occupational forecasting and labor market research. In the AKU respondents are first interviewed in two consecutive quarters, then there is a delay of two quarters, and then the respondent are interviewed again for two consecutive quarters. The sample was approximately 10- 11,000 respondents each quarter until 1988. Labour Force Survey 1975 is the fourth complete annual AKU. Originally it was intended that the AKU would be an analytical supplement to the monthly employment statistics which were based on the insurance fund membership. The health insurance-based statistics, however fell away when health insurance was included in the National Insurance Scheme from 1 January 1971. AKU has gradually evolved to become the main source of knowledge about the labor market of the state.

In 1975 the SSB on the sampling plan for the surveys, see Art.37: About the use of samples at the office for interview surveys, Statistics Norway (Steinar Tamsfoss), and SES 33: Sampling Methods Applied by Statistics Norways sample surveys (Ib Thomsen). Meanwhile, the method of estimation for inflating the national figures changed, so that there are adequate numbers of regions from 1975. The reorganization in 1975 meant that the interview was carried out differently in groups than before and after. This meant, among other things, a break in the panel structure of the AKU.

The Labour Force Survey 1976 adopted a slightly modified questionnaire and came back to the original 6-quarters rotation schedule. The new questionnaire meant that people in the group, and family workers temporarily absent from work was identified in a better way. This resulted in approximately 30 to 35,000 more were counted as employed. The group of job seekers without earned income was also expanded to include involuntarily laid off. The questions about the under- and overemployment in the original form was deleted.

挪威统计局自1972年第一季度起开展官方季度劳动力调查（Labor Force Surveys，缩写AKU）。本次调查的目的是为劳动主管部门及其他相关方提供人口职业结构及其随时间推移的发展变化情况，为职业预测与劳动力市场研究提供基础数据与统计资料。在AKU调查中，受访者首先在连续两个季度接受访问，随后间隔两个季度，之后再次连续两个季度接受访问。1988年之前，每季度的受访者样本量约为10000至11000人。1975年劳动力调查为第四份完整的年度AKU调查。最初，AKU旨在作为基于保险基金参保数据的月度就业统计的分析补充；然而，自1971年1月1日健康保险纳入国民保险计划起，基于健康保险的统计数据便不再使用。如今AKU已逐步发展为该国劳动力市场相关信息的核心来源。

1975年，挪威统计局（SSB）发布了本次调查的抽样方案，相关内容可参见：第37号文件《访谈调查办公室的样本使用规范》（挪威统计局，Steinar Tamsfoss）以及SES 33：《挪威统计局抽样调查应用的抽样方法》（Ib Thomsen）。与此同时，全国数据的加权估算方法得到调整，自1975年起可提供足够细分的地区层面数据。1975年的机构调整使得受访组的访问流程与调整前后均有所不同，这一变化使得AKU的追踪调查结构出现中断，除此之外还带来了其他影响。

1976年劳动力调查采用了小幅修订后的问卷，并恢复了最初的6季度轮换方案。新问卷能够更精准地识别群体务工人员以及临时离岗的家庭帮工，这使得就业人数统计增加了约30000至35000人。无劳动收入的求职者群体范围也得到扩大，纳入了非自愿失业人员；原问卷中关于就业不足与过度就业的相关问题被删除。
