SWIP - Swedish income panel 1976

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，旨在为研究移民如何融入瑞典劳动力市场提供可能。它包含大量外国出生者和瑞典出生者的样本，来自登记册的收入信息已累计近40年。此外，还可获取配偶的收入信息，以及部分父母的收入信息。这使得基于相对狭义定义构建家庭收入衡量指标成为可能。然而，自1998年起，更多信息的加入使得将18岁以上子女及其收入纳入家庭成为可能。通过与其他补充登记册匹配，已添加了以下信息：20世纪90年代期间失业或参与劳动力市场项目人员的相关数据、1978年以来已故者的死因信息，以及来自不同原籍的新移民信息。

事实证明，该数据库除了可用于最初推动面板建立的研究问题外，对其他研究问题的分析也相当有用。该面板已被用于劳动力市场中移民的跨国比较、不同人口细分群体的收入流动性分析，以及队列收入发展趋势分析。已有针对移民领取社会救助情况的分析，以及收入代际流动、年轻移民和第二代移民劳动力市场状况的研究。正在进行的工作包括劳动力市场培训项目的评估，以及移民提前退休情况的研究。计划中的工作包括20世纪80-90年代期间从儿童到成年的经济转型研究，以及移民儿童受《社会服务法》和《青少年照顾法》相关措施影响频率的研究。

通过与其他国家更知名的收入面板对比，可更好地理解瑞典收入面板的潜力。例如，瑞典收入面板（SWIP）的覆盖年限更长，样本量也大于德国社会经济面板（GSOEP）。另一方面，仅从登记册获取信息的特点使得该瑞典面板的变量丰富度较低。哥德堡收入面板与奥尔胡斯劳动力市场和社会研究中心针对丹麦人口的劳动力市场面板之间存在显著相似性。
