摘要
---------------------------
为监测政府就业促进政策实施效果，需要以极短的时间间隔收集就业与失业数据。鉴于此需求，斯里兰卡劳动力调查被设计为基于季度进行的调查，旨在衡量斯里兰卡就业、失业及劳动力的水平和趋势。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
---------------------------
- 研究经济活跃或非活跃人口。
- 分析主要行业分组和就业状况下的就业情况。
- 按教育水平和年龄段确定失业率。
- 研究非正式部门就业情况。
- 确定按部门和主要行业划分的就业不足率。

地理覆盖范围
---------------------------
全国范围

不包括机构囚犯、军事营房和住宿设施的人员，以及拥有超过5名住宿者和寄宿者的家庭也被排除在调查之外。

分析单元
---------------------------
10岁及以上的总人口个体

总体
---------------------------
居住在斯里兰卡非机构家庭中的工作年龄人口（10岁及以上）

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

抽样程序
---------------------------
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的估计值。覆盖范围包括斯里兰卡的所有家庭。

为1994年人口调查创建的住宅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最终抽样单位选择了10个住宅单位的系统抽样。

1600个人口普查区通过PPS系统抽样选择。在每个选定的PSU中进行列表操作，以提供第二阶段选择的框架。在PSU内选择住宅单位时采用系统抽样，并从随机起点开始。

抽样偏差
---------------------------
1999年进行的调查范围仅限于七个省份，排除了北部和东部省份，这是由于上述两个省份的现有情况。

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
- 适用于所有就业人员的共同问题

当前调查的概念和方法与1990年调查初期引入的非常相似。然而，多年来已进行了一些修改，以提高数据的准确性和实用性。[问卷附在“外部资源”部分]。
