SWIP - Swedish income panel 2002, RTB family

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，SWIP）最初于20世纪90年代初建立，旨在支持移民在瑞典劳动力市场的同化进程相关研究。该数据集包含大量外国出生与瑞典本土出生人群的样本，涵盖近40年的行政登记收入信息。此外，还包含配偶的收入信息，以及部分父母（母亲与父亲）的收入数据，这使得基于相对狭义的定义构建家庭收入衡量指标成为可能。不过自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。通过与多类额外登记数据匹配，该数据集还补充了以下信息：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数据、1978年以来已故人群的死因数据，以及来自不同原籍地的近期入境移民相关信息。

后续研究发现，该数据集除了最初搭建该面板的研究目标外，还可用于诸多其他研究议题。该面板已被用于劳动力市场移民的跨国对比研究、不同人口细分群体的收入流动性分析，以及同队列人群的收入发展趋势研究。已有研究涵盖了移民的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。当前正在开展的研究包括劳动力市场培训项目评估，以及移民提前退休相关研究。未来计划开展的研究包括：20世纪80年代与90年代期间儿童向成年阶段的经济转型研究，以及移民子女受《社会服务法》与《青年照料法》规制措施的频次相关研究。

若将瑞典收入面板与其他国家更为知名的收入面板进行对比，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），SWIP覆盖的年限更长、样本规模更大。但另一方面，由于所有信息均仅来自行政登记数据，该瑞典面板的变量丰富度相对不足。哥德堡收入面板与丹麦奥胡斯劳动力市场与社会研究中心搭建的丹麦人群劳动力市场面板，存在显著的相似性。
