Income- and Property Survey 1987

Statistics Norway carried out extensive income and property surveys in 1958, 1962, 1967, 1970, 1973, 1976, 1979 and 1982. From 1984 Statistics Norway switched to yearly surveys, this change mostly effected the sample size and sampling issues and not the type of information that is collected. The information is mostly decided based on publicly available taxation data. The income and property survey data is not a regular sampling survey, they are based on a selection that is drawn from the Tax Administration registries. Therefore, foreign citizens are included if they are part of the National registry, which all individuals with a work and residence permit normally are. Children born during the year are included regardless of date of birth, and the same is true of deceased individuals. The purpose of the survey is to shine a light on the income of both the whole population and within different groups. One of the main goals is to create statistics about households, households being understood as those who live and eat together, and to create an overview of the distribution of individuals and household based on income size, socioeconomic groups, types of households, geography etc. Another main point is to collect income and property data as background information for the Level of Living and consumer expenditure surveys. Information on all types of income, assets, tax deductions, and disposable income for individuals and households. Some information are gathered from other registers, for example marital status and family composition, while information about household composition is gathered through interviews. Family is a narrower concept than a household, a family can consist of single, unmarried fathers or mothers with children or married couples with or without children. A household consists of all individuals who lives and eats together and can therefore consist of several families. Experience shows that ca. 90% of all households consists of one family. (see NOS 98/11) Tax free incomes like social benefits, gifts and profits are not included because of the rules of taxation. Rules for percentage taxation of property, valuation of benefits in kind, private withdrawals, depreciation, etc. also create a number of problems. In addition to tax information, information about education, occupation and industry of individuals are included. For households the composition, type and who the main income earner is, is included. Data from The National Education registry, The Norwegian State Educational Loan Fund, The Housebank, Ministry of Labour and Social Inclusion and National Social Security Administration.挪威统计局（Statistics Norway）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与财产调查。自1984年起，挪威统计局转为开展年度调查，此次调整主要影响样本规模与抽样设计，并未改变所采集的信息类型。所采集的信息大多基于公开可获取的税务数据。本次收入与财产调查并非常规抽样调查，其样本选自挪威税务总局（Tax Administration）的登记名册。因此，凡纳入国家登记系统的外籍公民均被纳入调查范围——通常持有工作与居留许可的个人均会被纳入该系统。当年出生的儿童无论出生日期为何均会被纳入调查，已故个人亦同。本次调查旨在全面反映全体国民及不同群体的收入状况。其核心目标之一是编制住户（household）相关统计数据——此处的住户指共同居住、共同用餐的群体，并基于收入规模、社会经济群体、住户类型、地域分布等维度，梳理个人与住户的收入分布概览。另一核心目标是采集收入与财产数据，作为生活水平调查与消费支出调查的背景信息。具体涵盖个人与住户的各类收入、资产、税收减免及可支配收入相关信息。部分信息源自其他登记系统，例如婚姻状况与家庭（family）构成；而住户构成信息则通过访谈采集。家庭的概念窄于住户：家庭可涵盖独居个体、携子女的未婚单亲父母，或有无子女的已婚夫妇；而住户指所有共同居住、共同用餐的个人，因此可包含多个家庭。相关经验表明，约90%的住户仅包含一个家庭（详见NOS 98/11）。根据税务相关规定，社会福利、赠与所得及免税利润等免税收入未被纳入统计。财产比例征税规则、实物福利估值、私人提款、折旧核算等相关规定，也为数据采集带来了诸多挑战。除税务信息外，调查还涵盖个人的教育背景、职业及所属行业相关信息。针对住户，则采集其构成、类型及主要收入来源者相关信息。本次调查的数据来源包括国家教育登记系统、挪威国家教育贷款基金、住房银行（Housebank）、劳工与社会融入部（Ministry of Labour and Social Inclusion）以及国家社会保障管理局（National Social Security Administration）。
