Income- and Property Survey 1984, Household File

Statistics Norway (SSB) conducted wide-ranging Income Studies in 1958, 1962, 1967, 1970, 1973, 1976, 1979 and 1982. As of 1984, SSB moved to a system of annual surveys. This entailed changes, more in terms of sample size and sampling method than the type of information that was gathered. The information is mainly decided by what is available in public tax assessment records. The Income Studies should not be considered ordinary sample surveys, they are based on a sample drawn from registers from the Norwegian equivalent to the Internal Revenue Service. This means that foreign citizens would be part of the sample if they are registered in the Central Person Register, which they will normally be if they have valid work and residence permits. Children born during the year in question will be included in the sample regardless of birth date, and so will persons dying that the year.

The objective of the Income Studies have been to elucidate the income conditions for the entire population and for different groups. A main point is to gather statistics on households that live and eat together, as well as getting an overview of the distribution of persons and households by size of income, socio-economic groups, household type, geography etc. Another objective is to collect income and fortune data as a backdrop for the Level of Living and Consumer surveys. Information is gathered om all types of income, fortune, taxes, income for individuals and households. Some information is added from other registers (amongst others, marital status and family composition, whilst information on household composition is gathered through interviews. In addition, one generally includes information on education, profession and occupation for individuals and household composition, type and primary income recipients for the households.

There exist both a household file and a person file. These are documented separately. This is the household file.

挪威统计署（Statistics Norway, SSB）曾于1958年、1962年、1967年、1970年、1973年、1976年、1979年及1982年开展多轮大规模收入研究。截至1984年，SSB全面切换为年度调查体系，此次转型在样本量与抽样方法层面的调整幅度，大于其在采集信息类型上的变动。本研究采集的信息主要源自挪威公共税务评估记录中的可获取数据。需注意，本收入研究并非普通抽样调查，其样本取自挪威对应美国国税局（Internal Revenue Service）的税务登记库。这意味着，若外国公民在挪威中央人口登记册（Central Person Register）完成登记——通常持有有效工作及居留许可的外国公民均可完成该登记——即可被纳入样本。同年出生的新生儿与当年身故的人员，同样会被纳入样本范围。

本收入研究的核心目标是阐明全体国民及不同群体的收入状况，重点在于统计共同居住与共同生活的家庭的相关数据，并梳理按收入规模、社会经济群体、家庭类型、地域划分的人口与家庭分布概况。另一项研究目标是收集收入与财富数据，作为生活水平调查与消费调查的背景支撑。研究采集各类个人与家庭的收入、财富、税负相关数据。部分信息取自其他登记库（包括婚姻状况与家庭构成等），而家庭构成信息则通过访谈获取。此外，通常还会纳入个人的教育背景、职业与工种信息，以及家庭的构成、类型与主要收入来源者信息。

本数据集同时包含家庭档案（household file）与个人档案（person file），二者分别进行文档说明，本次提供的为家庭档案。
