Income Study 2001, 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.挪威统计统计局（Statistics Norway, SSB）曾于1958年、1962年、1967年、1970年、1973年、1976年、1979年及1982年开展了多轮范围广泛的收入研究。截至1984年，SSB转为采用年度调查体系，此次转型在样本量与抽样方法层面的调整幅度大于所采集信息类型的变动。所采集的信息主要取决于公共税务评估记录中可获取的内容。 该收入研究不应被视为普通抽样调查，其样本取自挪威对应美国国税局（Internal Revenue Service, IRS）的登记系统。这意味着，外国公民若在挪威中央人口登记系统（Central Person Register）完成登记，即可纳入样本——而持有有效工作及居留许可的外国公民通常都会完成该登记。当年出生的儿童无论出生日期为何，均会被纳入样本；同年去世的人员亦同。 收入研究的目标是阐明全体人口及不同群体的收入状况。核心要点之一是采集共同居住与共同生活的家庭的统计数据，并梳理按收入规模、社会经济群体、家庭类型、地域等维度划分的人口与家庭分布情况。另一项目标是收集收入与财富数据，作为生活水平调查及消费者调查的背景支撑。本次采集的信息涵盖个人与家庭的各类收入、财富及纳税情况。部分信息取自其他登记系统（例如婚姻状况与家庭构成），而家庭构成信息则通过访谈采集。此外，通常还会纳入个人的教育背景、职业与从业情况，以及家庭的构成、类型与主要收入来源者信息。 该数据集同时包含家庭文件与个人文件，二者分别独立归档。本文档为家庭文件。
