SWIP - Swedish income panel 1992

The Swedish income panel was originally set up in the beginning of the 90s to make studies of how immigrants assimilate in the Swedish labour market possible. It consists of large samples of foreign-born and Swedish-born persons. Income information from registers is added for nearly 40 years. In addition income information relating to spouses is also available as well as for a subset of mothers and fathers. This makes it possible to construct measures of household income based on a relatively narrow definition. However, starting in 1998 there is also more information making it possible to include children over 18 and their incomes in the family. By matching with some different additional registers information has been added for people who have been unemployed or involved in labour market programmes during the 90s, on causes of deaths for people who have deceased since 1978 and on recent arrived immigrants from various origins. It has turned out that the data-base is quite useful for analysing research-questions other than originally motivating construction of the panel. The panel has been used for cross country comparisons of immigrants in the labour market and to analyse income mobility for different breakdowns of the population, and analyses the development in cohort income. There have been analyses of social assistance receipt among immigrants as well as studies of intergeneration mobility of income, the labour market situation of young immigrants and the second generation of immigrants. On-going work includes evaluation of labour market training programmes and studies of early retirement among immigrants. Planned work includes studies of the economic transition from child to adulthood during the 80s and 90s as well as studies of how frequent immigrant children are subject to measures under the Social Service Act and the Care of Youth Persons Act. The potentials of the Swedish Income Panel can be understood if one compares it with better known income-panels in other countries. For example SWIP covers more years and has a larger sample than the German Socio-Economic Panel (GSOEP). On the other hand, the fact that information is obtained from registers only makes this Swedish panel less rich in variables. There are striking parallels between the Gothenburg Income Panel and the labour market panel at the Centre for Labour Market and Social Research in Aarhus for the Danish population.瑞典收入面板（Swedish Income Panel）最初于20世纪90年代初建立，旨在为开展移民在瑞典劳动力市场的同化情况研究提供条件。该面板涵盖了大量外国出生与瑞典本土出生的人群样本，收录了近40年的行政登记收入信息。此外，还包含配偶的收入数据，以及部分父母的收入信息，这使得基于相对狭义的定义构建家庭收入核算指标成为可能。但自1998年起，新增了更多信息，可将18岁以上子女及其收入纳入家庭收入统计范畴。通过与多类补充行政登记库匹配，该面板补充了以下数据：20世纪90年代期间失业或参与劳动力市场项目的人群相关信息、1978年以来已故人群的死因数据，以及不同来源地新近入境移民的相关资料。 后续研究发现，该数据库除最初用于面板构建的研究主题外，还可用于诸多其他研究问题的分析。该面板已被用于开展移民劳动力市场表现的跨国比较研究，针对不同人口细分群体的收入流动性展开分析，并对同期组群的收入发展趋势进行研究。现有研究涵盖了移民社会救助申领情况分析、收入代际流动性研究、年轻移民及移民第二代的劳动力市场状况研究等方向。目前正在开展的研究包括劳动力市场培训项目评估以及移民提前退休情况研究；计划开展的研究则包括20世纪80年代与90年代期间儿童向成年的经济转型研究，以及移民子女受《社会服务法》与《青少年照料法》相关措施约束的频率分析。 将瑞典收入面板与其他国家知名收入面板进行对比，便可明晰其研究潜力。例如，相较于德国社会经济面板（German Socio-Economic Panel, GSOEP），瑞典收入面板的观测年限更长、样本规模更大。但另一方面，由于该面板仅使用行政登记数据，其变量丰富度相对有限。哥德堡收入面板（Gothenburg Income Panel）与奥胡斯劳动力市场与社会研究中心针对丹麦人群构建的劳动力市场面板之间，存在诸多显著的相似之处。
