Labour Force Survey - 2001 - Sri Lanka

Abstract
---------------------------

The employment/unemployment data are required at very short intervals to monitor the program made in the employment generating policies of the government. To satisfy this need, Sri Lanka Labour Force Survey was designed as a quarterly basis survey to measure the levels and trends of employment, unemployment and labour force in Sri Lanka. Thus the survey is repeated four times each year since the first quarter of 1990.

Key objectives of the survey
- To study the economically active / inactive population.
- To analyze employment by major industry group and employment status.
- To determine unemployment rates by level of education and by age group
- To study the informal sector employment.
- To determine the underemployment rates by sector and by major industries

Individuals from the population aged 10 years or more

Kind of data

Sample survey data [ssd]

Sampling procedure
---------------------------

The Survey is conducted quarterly to produce estimates of employment, unemployment, labour force
participation and basic demographic characteristics. The scope of coverage includes all households in Sri Lanka.

The list of housing units created for Demographic Survey 1994 were taken as sample frame. Sample lists were
selected from the above frame taken as Primary Sampling Unit (PSU). A systematic Sample of 15 housing units per
PSU was selected on final sampling units.

The total annual sample size is 15915 housing units equaly, distributed as 265 PSUs per each quarter and 15 housing
units (SSUs) per PSU. The allocation to the domains aims at ensuring approximately equal of reliability from domain
to domain.

The 1061 PSUs were selected by systematic Sampling from the PSUs created for Demographic Survey - 1994. A listing operation was conducted in each selected PSU to provide a frame for the second stage of selection. The selection of housing units within PSU was
systematic with random start.

Sampling deviation
---------------------------

The field work of the above survey conducted in 2001 was confined to seven provinces of the country excluding the
Northern and the Eastern provinces

Mode of data collection
---------------------------

Face-to-face [f2f]

Research instrument
---------------------------

The questionnaire covered questions under four main headings such as

Identification Information
Control data
Personal Information
Labour force Information
Questions common to all employed persons

Current survey concepts and methods are very similar to those introduced at the beginning of the
survey in 1990. However, some changes have been made over the years to improve the accuracy and
usefulness of the data. [Questionnaire is attached in the External Resources section].

摘要
---------------------------

政府就业创造政策的实施监控需要非常短时间间隔的就业/失业数据。为满足这一需求，斯里兰卡劳动力调查被设计为基于季度的调查，以衡量斯里兰卡就业、失业和劳动力的水平和趋势。因此，自1990年第一季度以来，该调查每年重复四次。

调查的主要目标
- 研究经济活跃/非活跃人口。
- 分析按主要行业分组和就业状态的就业情况。
- 确定按教育水平和年龄组划分的失业率。
- 研究非正式部门就业。
- 确定按部门和主要行业划分的就业不足率。

10岁及以上的人口个人

总体
---------------------------

数据类型

样本调查数据 [ssd]

抽样程序
---------------------------
该调查每季度进行一次，以产生就业、失业、劳动力参与率和基本人口统计特征估计。覆盖范围包括斯里兰卡的所有家庭。

1994年人口调查创建的住宅单位列表被用作抽样框架。从上述框架中选取的样本列表被作为一级抽样单位（PSU）。每个PSU最终抽样单位中选择了15个住宅单位的系统抽样。

总年样本量为15915个住宅单位，均匀分布在每个季度265个PSU和每个PSU 15个住宅单位（SSU）。对领域的分配旨在确保从领域到领域的大致可靠性。

1061个PSU通过从为1994年人口调查创建的PSU中进行的系统抽样进行选择。在每个选定的PSU中进行了列表操作，以提供第二阶段选择的框架。PSU内住宅单位的选择是系统的，以随机开始。

抽样偏差
---------------------------
2001年进行的上述调查工作仅限于国家除北部和东部省份外的七个省份

研究工具
---------------------------
问卷涵盖了以下四个主要标题下的问题：

识别信息
控制数据
个人信息
劳动力信息
适用于所有雇员的共同问题

当前的调查概念和方法与1990年调查开始时引入的非常相似。然而，多年来已进行了一些更改，以提高数据的准确性和实用性。[问卷附在“外部资源”部分]。
