Income- and Property Survey 1982, Individual Level Data

Statistics Norway have conducted comprehensive Income and Property in 1958, 1962, 1967, 1970, 1973, 1976, 1979 and 1982. From 1984, Statistics Norway changed to another system with annual surveys, however the changes made were mostly the sample sizes, and not the information collected. The information collected is mainly decided through the information available in the public taxation data. The income and property surveys are not considered ordinary sample surveys as the surveys are based on samples drawn from the Norwegian Tax Administrations registers. This entails that foreign nationals are included in the surveys if they are registered in the national register, which they would normally be if they have a working or residence permit. Children born in the course of the year will be included no matter their birth date, and the same applies for persons that deceased in the course of the year.

The Income and Property survey 1982 was distinguished from earlier income and property surveys - as the sample was influenced by the survey being connected to the Level of Living Survey 1983, the Survey of Consumer Expenditure 1982, The Labour Force Survey 1983 and part of the material for the elders Level of Living survey. The sample therefore consisted of 4 independent self-weighted samples, a total of 8.845 households or 24.453 persons. The purpose of the surveys has been to shed light on income situation for the whole population and for different groups. A main point is to create statistics concerning households that live and eat together, to create an outline of the distribution of persons and households after income size, socioeconomic groups, household type, geography, ect. Information concerning all forms of income, property, tax deduction, dispositional income for individuals and households was collected. This data was mainly collected from the Norwegian Tax Administrations registers. Some information was connected from other registers; this mainly concerns marital status and family compositions, while information concerning household compositions is collected through interviews. Family is a narrower term than household, a family can consist of singles, unmarried fathers or mothers with children, or married couples with or without children. A household can on the contrary include all persons that live and eat together and can therefore consist of several families. Experience shows however that around 90% of all households only consists of one family. (See NOS B 569). Tax-free incomes, as for instance social benefits, gifts and winnings will not be included because of the tax rules. Rules for imputed rental value/income of property, value determination of benefits, private outlets, and impairments etc. also created some problems.

In addition to the tax information it is usually included information concerning among other things education, profession and industry for individuals and for the household: composition, type and the persons considered main provider. An important problem with the 1982-data was that the individuals-data file does not contain household numbers. That is why the two files on household and individual level cannot be connected.

挪威统计局（Statistics Norway）先后于1958年、1962年、1967年、1970年、1973年、1976年、1979年及1982年开展了全面的收入与财产调查。自1984年起，挪威统计局改用年度调查体系，但此次调整仅变更了样本规模，未对采集的信息范畴作出调整。采集的信息主要依托公共税务数据中的可用内容确定。本次收入与财产调查不属于普通抽样调查，其样本源自挪威税务管理局的登记名册，因此凡在挪威国家登记在册的外籍人士均可纳入调查——通常持有工作许可或居留许可的外籍人士均完成了国家登记。本年度内出生的儿童无论出生日期均会被纳入调查，年内去世的人员亦适用此规则。

1982年的收入与财产调查与此前各轮调查存在显著差异，因该调查样本与1983年生活水平调查、1982年消费者支出调查、1983年劳动力调查以及老年人生活水平调查的部分数据集相关联。本次样本包含4个独立的自加权样本（self-weighted samples），总计8845户家庭、24453名个体。本系列调查的核心目标是阐明全体国民及不同群体的收入状况，重点在于编制共同居住与共同进餐的家庭统计数据，梳理按收入规模、社会经济群体、家庭类型、地域划分等维度的人口与家庭分布格局。调查采集了个体与家庭的各类收入、财产、税收扣除额及可支配收入相关信息，数据主要源自挪威税务管理局的登记名册。部分信息从其他登记册关联获取，主要包括婚姻状况与家庭构成，而住户构成信息则通过访谈采集。家庭（family）的定义窄于住户（household）：家庭可指单身人士、未婚父母携带子女，或已婚夫妇携/不携子女；住户则可涵盖所有共同居住、共同进餐的人员，因此可能包含多个家庭。但经验数据显示，约90%的住户仅包含单个家庭（详见NOS B 569）。根据税收法规，社会福利、赠与与奖金等免税收入不计入统计。此外，估算房产虚拟租金价值/收入、福利价值核定、私人收支渠道及资产减值等规则也带来了部分统计难题。

除税务信息外，调查通常还会采集个体与家庭的教育、职业、行业信息，以及住户构成、类型与主要供养人信息。1982年数据集存在一项关键局限：个体数据文件未包含住户编号，因此住户层面与个体层面的两份文件无法进行关联匹配。
