SWIP - Swedish income panel 1996

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年代初搭建，旨在支撑移民在瑞典劳动力市场的同化情况研究。该数据集包含大量外国出生与瑞典出生人群的样本，涵盖近40年的登记收入信息。此外，还包含配偶的收入数据，以及部分父母的收入信息，据此可基于相对狭义的定义构建家庭收入核算指标。不过自1998年起，新增的信息允许将18岁以上子女及其收入纳入家庭收入核算范畴。通过与多类补充登记数据匹配，该数据集进一步补充了以下信息：20世纪90年代期间失业或参与劳动力市场项目人群的相关数据、1978年以来已故人群的死亡原因数据，以及不同来源地新近入境移民的相关信息。 后续研究表明，该数据集不仅可用于初始搭建时设定的研究主题，还能有效支撑诸多其他研究议题。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分析收入流动性，并探究队列收入的动态变化趋势。已有研究借助该数据集分析了移民的社会救助申领情况、收入代际流动问题、年轻移民及移民第二代的劳动力市场处境。目前正在开展的研究包括劳动力市场培训项目效果评估，以及移民提前退休情况研究。未来规划的研究方向包括：探究20世纪80至90年代人群从儿童到成年的经济转型历程，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情况。 将瑞典收入面板与其他国家知名收入面板进行对比，可清晰展现其研究潜力。例如，瑞典收入面板（SWIP）的观测年限更长、样本规模也大于德国社会经济面板（German Socio-Economic Panel, GSOEP）。但另一方面，由于该面板仅采用登记数据作为信息来源，其变量丰富度相对有限。哥德堡收入面板（Gothenburg Income Panel）与丹麦奥胡斯劳动力市场与社会研究中心针对丹麦人群搭建的劳动力市场面板存在诸多显著相似之处。
