Labour Force Survey, April 2017 [Canada]

The Labour Force Survey provides estimates of employment and unemployment which are among the timeliest and important measures of performance of the Canadian economy. With the release of the survey results only 10 days after the completion of data collection, the LFS estimates are the first of the major monthly economic data series to be released. The Canadian Labour Force Survey was developed following the Second World War to satisfy a need for reliable and timely data on the labour market. Information was urgently required on the massive labour market changes involved in the transition from a war to a peace-time economy. The main objective of the LFS is to divide the working-age population into three mutually exclusive classifications - employed, unemployed, and not in the labour force - and to provide descriptive and explanatory data on each of these. LFS data are used to produce the well-known unemployment rate as well as other standard labour market indicators such as the employment rate and the participation rate. The LFS also provides employment estimates by industry, occupation, public and private sector, hours worked and much more, all cross-classifiable by a variety of demographic characteristics. Estimates are produced for Canada, the provinces, the territories and a large number of sub-provincial regions. For employees, wage rates, union status, job permanency and workplace size are also produced. These data are used by different levels of government for evaluation and planning of employment programs in Canada. Regional unemployment rates are used by Employment and Social Development Canada to determine eligibility, level and duration of insurance benefits for persons living within a particular employment insurance region. The data are also used by labour market analysts, economists, consultants, planners, forecasters and academics in both the private and public sector. Note: Because missing values are removed from this dataset, any form of non-response (e.g. valid skip, not stated) or don't know/refusal cannot be coded as a missing. The \"Sysmiss\" label in the Statistics section indicates the number of non-responding records for each variable, and the \"Valid\" values in the Statistics section indicate the number of responding records for each variable. The total number of records for each variable is comprised of both the sysmiss and valid values. LFS revisions: LFS estimates were previously based on the 2001 Census population estimates. These data have been adjusted to reflect 2006 Census population estimates and were revised back to 1996. The census metropolitan area (CMA) variable has been expanded from the three largest CMAs in Canada to nine. Two occupation variables based on the 2016 National Occupation Classicifcation have been reintroduced: a generic 10- category variable (NOC_10) and a detailed 40-category variable (NOC_40). A new variable on immigrant status (IMMIG) has been introduced, which distingushes between recent immigrants and established immigrants. Fourteen variables related to family and spouse/partner's labour force characteristics have been removed, as well as eight out of date variables which have been removed from the record layout.劳动力调查（Labour Force Survey）提供的就业与失业估算数据，是衡量加拿大经济运行表现最及时且最重要的指标之一。该调查在数据采集完成仅10天后便发布结果，因此其估算数据是首批发布的主要月度经济数据序列之一。 加拿大劳动力调查是在第二次世界大战后为满足劳动力市场可靠及时的数据需求而设立的。当时社会亟需获取战时经济向和平时期经济转型过程中，劳动力市场发生的大规模变革相关数据。 劳动力调查的核心目标是将劳动年龄人口划分为三个互斥类别——就业者、失业者以及非劳动力群体，并为每一类群体提供描述性与解释性数据。 劳动力调查的数据可用于计算广为人知的失业率，以及就业率、劳动参与率等其他标准劳动力市场指标。此外，该调查还可按行业、职业、公共与私营部门、工作时长等维度提供就业估算数据，且所有数据均可结合多种人口统计特征进行交叉分类。 调查估算数据覆盖加拿大全国、各省、各地区以及大量省以下区域。针对雇员群体，还会生成其工资水平、工会身份、岗位稳定性以及雇主规模等相关数据。 加拿大各级政府可利用这些数据开展就业项目的评估与规划。加拿大就业与社会发展部则会依据区域失业率，为特定就业保险区域内的人群确定其保险福利的申领资格、待遇水平与领取时长。劳动力市场分析师、经济学家、顾问、规划人员、预测人员以及学术界人士，无论来自私营还是公共部门，也都会使用这些数据。 备注：由于本数据集已剔除缺失值，任何形式的无应答（例如有效跳答、未填报）以及「不知道/拒绝回答」均无法被编码为缺失值。统计模块中的"Sysmiss"标签代表各变量的无应答记录数，而"Valid"（有效）值则代表各变量的有效应答记录数。每个变量的总记录数由系统缺失值与有效应答值两部分共同构成。 劳动力调查数据修订说明：此前劳动力调查的估算数据基于2001年人口普查的人口估算值，现已调整为以2006年人口普查的人口估算值为基准，并回溯至1996年完成数据修订。普查都市区（census metropolitan area, CMA）变量已从加拿大最大的3个普查都市区扩展至9个。基于2016年全国职业分类的两个职业变量已重新引入：分别为通用10分类变量（NOC_10）与细分40分类变量（NOC_40）。新增了一项关于移民身份的变量（IMMIG），可区分新移民与定居移民。本次修订移除了14项与家庭及配偶/伴侣劳动力特征相关的变量，同时从记录布局中删除了8项过时变量。
