Labour Force Historical Review, 1997 [Canada] [B2020]

The Labour Force Survey (LFS) is a household survey carried out monthly by Statistics Canada. Since its inception in 1945, the objectives of the LFS have been 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 categories. Data from the survey provide information on major labour market trends such as shifts in employment across industrial sectors, hours worked, labour force participation and unemployment rates, employment including the self-employed, full and part-time employment, and unemployment. It publishes monthly standard labour market indicators such as the unemployment rate, the employment rate and the participation rate. The LFS is a major source of information on the personal characteristics of the working-age population, including age, sex, marital status, educational attainment, and family characteristics. Employment estimates include detailed breakdowns by demographic characteristics, industry and occupation, job tenure, and usual and actual hours worked. This dataset is designed to provide the user with historical information from the Labour Force Survey. The tables included are monthly and annual, with some dating back to 1976. Most tables are available by province as well as nationally. Demographic, industry, occupation and other indicators are presented in tables derived from the LFS data. The information generated by the survey has expanded considerably over the years with a major redesign of the survey content in 1976 and again in 1997, and provides a rich and detailed picture of the Canadian labour market. Some changes to the Labour Force Survey (LFS) were introduced which affect data back to 1987. There are three reasons for this revision: The revision enables the use of improved population benchmarks in the LFS estimation process. These improved benchmarks provide better information on the number of non-permanent residents. There are changes to the data for the public and private sectors from 1987 to 1999. In the past, the data on the public and private sectors for this period were based on an old definition of the public sector. The revised data better reflects the current public sector definition, and therefore result in a longer time series for analysis. The geographic coding of several small Census Agglomerations (CA) has been updated historically from 1996 urban centre boundaries to 2001 CA boundaries. This affects data from January 1987 to December 2004. It is important to note that the changes to almost all estimates are very minor, with the exception of the public sector series and some associated industries from 1987 to 1999. Rates of unemployment, employment and participation are essentially unchanged, as are all key labour market trends. The article titled Improvements in 2006 to the LFS (also under the LFS Documentation button) provides an overview of the effect of these changes on the estimates. The seasonally-adjusted tables have been revised back three years (beginning with January 2004) based on the latest seasonal output.

劳动力调查（Labour Force Survey, LFS）是加拿大统计局（Statistics Canada）每月开展的一项住户调查。自1945年创立以来，该调查的核心目标是将劳动年龄人口划分为就业、失业及非劳动力三大互斥类别，并为每一类提供描述性与解释性数据。本次调查的数据可反映加拿大劳动力市场的主要趋势，包括各工业部门就业结构变动、工作时长、劳动力参与率与失业率、含自营就业者在内的就业情况、全职与兼职就业状况以及失业情况。其按月发布失业率、就业率与劳动力参与率等标准劳动力市场指标。劳动力调查同时是获取劳动年龄人口个人特征（包括年龄、性别、婚姻状况、受教育程度）与家庭特征相关信息的重要数据源。就业估算数据可按人口特征、行业、职业、工作年限以及标准与实际工作时长进行详细细分。本数据集旨在为使用者提供劳动力调查的历史数据。数据集包含的表格分为月度与年度两类，部分表格的历史可追溯至1976年。绝大多数表格可按省份及全国层面进行展示。基于劳动力调查数据生成的表格涵盖人口、行业、职业及其他各类指标。随着1976年与1997年两次对调查内容的重大修订，本次调查生成的信息体量逐年大幅扩充，能够全面且细致地刻画加拿大劳动力市场的全貌。本次劳动力调查实施了若干修订，其影响可追溯至1987年的历史数据。本次修订主要基于以下三项原因：其一，修订后可在劳动力调查的估算流程中采用优化后的人口基准值，该基准值能够更精准地反映非永久居民的数量；其二，对1987年至1999年的公共部门与私营部门数据进行了调整，此前该时段的公共与私营部门数据基于旧版公共部门定义，修订后的数据更贴合现行公共部门界定标准，由此可形成更长的可分析时间序列；其三，对若干小型普查集聚区（Census Agglomerations, CA）的地理编码进行了历史回溯更新，将其从1996年的城市中心边界调整为2001年的普查集聚区边界，该调整影响1987年1月至2004年12月的相关数据。需特别说明的是，除1987年至1999年的公共部门序列及部分相关行业数据外，其余绝大多数估算值的调整幅度极小。失业率、就业率与劳动力参与率，以及所有核心劳动力市场趋势均基本保持不变。题为《2006年劳动力调查改进说明》的文章（同样可在劳动力调查文档按钮对应的栏目中查看）概述了本次修订对各项估算值的影响。基于最新的季节性调整产出数据，经季节性调整的表格已回溯修订至三年前，即起始于2004年1月的数据。
