Labour Force Survey - 2000 - 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

Geographic coverage
---------------------------

National coverage. ( Excluding Nothern and Eastern provinces )

Analysis unit
---------------------------

Individuals from the population aged 10 years or more

Universe
---------------------------

Working age population (10 years and above) living in the non-institutional households in Sri Lanka

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 of survey conducted in year 2000 was confined to seven province of the country excluding the Northern and the Eastern provinces due to the prevailing situation in the above two 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
---------------------------
政府就业生成政策的实施监测需要以极短的间隔获取就业/失业数据。为此，斯里兰卡劳动力调查被设计为一种基于季度的调查，用以衡量斯里兰卡就业、失业和劳动力水平及趋势。因此，自1990年第一季度起，该调查每年重复四次。

调查的主要目标
- 研究经济活跃/不活跃的人口。
- 分析按主要行业组和就业状况划分的就业情况。
- 通过教育水平和年龄段确定失业率。
- 研究非正规部门的就业情况。
- 确定按部门和主要行业划分的过剩就业率。

地理覆盖范围
---------------------------
全国范围。 (不包括北部和东部省份)

分析单位
---------------------------
10岁及以上的人口个体

总体
---------------------------
居住在斯里兰卡非机构家庭的10岁及以上工作年龄人口

数据类型
---------------------------
样本调查数据 [ssd]

抽样程序
---------------------------
该调查按季度进行，以产生就业、失业、劳动力参与率和基本人口统计特征估计值。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房单位清单被用作抽样框架。从上述框架中选择了样本清单，作为一级抽样单位 (PSU)。每个 PSU 选择了一个系统样本，即每 PSU 15个住房单位。

总年样本量为15915个住房单位，均匀分布为每个季度265个 PSU 和每个 PSU 15个住房单位 (SSU)。分配到各个领域的目的是确保各领域之间可靠性的大致相等。

1061个 PSU 通过对为1994年人口调查创建的 PSU 的系统抽样进行选择。在每个选定的 PSU 中进行了编目操作，为第二阶段的选择提供框架。在 PSU 内部选择住房单位时采用系统抽样，随机起始。

抽样偏差
---------------------------
由于上述两个省份的现行情况，2000年进行的调查范围仅限于该国的七个省份，不包括北部和东部省份。

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
- 适用于所有受雇人员的共同问题

当前调查的概念和方法与1990年调查开始时引入的概念和方法非常相似。然而，多年来已进行了一些变化，以提高数据的准确性和实用性。[问卷附于外部资源部分]。
