Survey of Labour and Income Dynamics, 2009 [Canada]: Key File

The cross-sectional public-use microdata file for the Survey of Labour and Income Dynamics (SLID) is a collection of income, labour and family variables on persons in Canada and their families. SLID is an annual household survey covering the population of the 10 Canadian provinces with the exception of Indian reserves, residents of institutions and military barracks. The Survey of Labour and Income Dynamics began collecting data for reference year 1993. Initially, SLID was designed to be, first and foremost, a longitudinal survey, with primary focus on labour and income and the relationships between them and family composition. Then, the decision was made to extend the objectives of SLID to be the primary source of cross-sectional household income data. For many years, the Survey of Consumer Finances had provided public-use microdata files (PUMFs) to meet the needs of cross-sectional household income data users. SCF PUMFs were released up to and including reference year 1997. For the purpose of standard publications, Statistics Canada has made the transition from SCF to SLID between 1995 and 1996. Therefore, SLID cross-sectional PUMFs are being made available beginning with reference year 1996. The SLID files have been designed to be analogous to those produced for the SCF. The type of income data collected by SLID was identical to that of the former household income survey SCF (Survey of Consumer Finances), with the distinction that SLID respondents had the choice of a traditional income interview or granting permission to Statistics Canada to use their T1 income tax data.劳动力与收入动态调查（Survey of Labour and Income Dynamics，以下简称SLID）的横断面公共使用微观数据文件，收录了加拿大境内民众及其家庭的收入、就业与家庭相关变量信息。SLID为年度家庭调查，覆盖加拿大10个省份的全体人口，但排除印第安保留地居民、机构收容人员及军营驻地人员。该调查自1993年起开始采集对应参考年份的数据。最初，SLID的核心设计定位为纵向调查，主要聚焦劳动力与收入状况，以及二者与家庭结构之间的关联。此后，相关决策方拓展了SLID的调查目标，使其成为横断面家庭收入数据的核心来源。长期以来，消费者财务调查（Survey of Consumer Finances，以下简称SCF）一直通过发布公共使用微观数据文件（public-use microdata files, PUMFs），满足横断面家庭收入数据使用者的需求。SCF公共使用微观数据文件的发布时限覆盖至1997年参考年份（含1997年）。为满足标准出版物的数据需求，加拿大统计局于1995年至1996年间完成了从SCF到SLID的数据源过渡。因此，SLID的横断面公共使用微观数据文件自1996年参考年份起正式对外发布。SLID数据文件的设计思路与此前SCF产出的同类文件保持一致。SLID采集的收入数据类型与此前的家庭收入调查SCF（消费者财务调查，Survey of Consumer Finances）完全一致，唯一区别在于SLID受访者可二选一：一是接受传统收入访谈，二是授权加拿大统计局使用其T1个人所得税申报数据。
