Labour Force Survey, October 1991 [Canada] [Rebased]

<p>The Labour Force Survey provides estimates of employment and unemployment which are among the most timely and important measures of performance of the Canadian economy. With the release of the survey results only 13 days after the completion of data collection, the LFS estimates are the first of the major monthly economic data series to be released. </p> <p>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. </p> <p>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. </p> <p>These data are used by different levels of government for evaluation and planning of employment programs in Canada. Regional unemployment rates are used by Human Resources 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. </p> <p>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. </p> <p>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. </p>

劳动力调查（Labour Force Survey, LFS）可提供就业与失业相关估算数据，是衡量加拿大经济运行状况最及时且关键的指标之一。该调查在数据收集完成仅13天后便发布结果，其估算数据也是首个公布的主要月度经济数据序列。
加拿大劳动力调查诞生于第二次世界大战结束后，旨在满足劳动力市场对可靠及时数据的需求。当时社会亟需了解战后向和平经济转型过程中出现的大规模劳动力市场变革。该调查的核心目标是将劳动年龄人口划分为就业、失业及不在劳动力市场三大互斥类别，并为每一类群体提供描述性与解释性数据。
LFS数据可用于测算广为人知的失业率，以及就业率、劳动参与率等各类标准劳动力市场指标。此外，该调查还可按行业、职业、公私部门、工作时长等维度生成就业估算数据，且所有统计维度均可结合多种人口统计特征进行交叉分类。调查估算覆盖加拿大全国、各省、各地区以及大量省以下次级区域。针对雇员群体，还会生成工资水平、工会身份、岗位持久性及工作场所规模相关数据。
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工作。加拿大人力资源开发部（Human Resources Development Canada）会依据区域失业率，为特定就业保险区域内的参保人员核定保险待遇的申领资格、待遇标准及发放时长。此外，劳动力市场分析师、经济学家、咨询顾问、规划人员、预测人员及学术界人士，无论身处私营还是公共部门，也都会使用该调查数据。
备注：本数据集已剔除缺失值，因此任何形式的无应答情况（如有效跳转、未注明）或“不知道/拒绝作答”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”值则代表各变量的有效应答记录数。各变量的总记录数由Sysmiss记录与有效记录共同构成。
LFS数据修订说明：此前LFS的估算数据基于2001年人口普查的人口估算值。本次已对数据进行调整，使其符合2006年人口普查的人口估算标准，并将修订范围回溯至1996年。
