Namibia Labour Force Survey 2012 - Namibia

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

The Namibia Labour Force Survey (NLFS) is a household-based sample survey. Namibia's first Labour Force Survey was conducted in 1997, and the survey has been conducted every 4 years since then, by the Ministry of Labour and Social Welfare (MoLSW). The NLFS 2012 is the first Labour Force Survey conducted by the new Namibia Statistics Agency, established as an autonomous National Statistics Office in 2011. The NLFS 2012 collected labour market data on people aged 15 years and above for the week prior to the survey week (16-27 October 2012).

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

The survey had national coverage. The lowest level of geographic aggregation of the data is Region (the 13 regions in the country).

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

The units of analysis in the survey includes households and individuals

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

The universe of the survey was all household members. Homeless people and the people who are living in institutions (institutional population) are excluded.

Kind of data
---------------------------

Sample survey data [ssd]

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

The National Sampling Frame maintained by the NSA is based on the Enumeration Areas (EAs) of the 2011 Population and Housing Census and the households within the EAs. The frame was revised and updated in July 2011. The revised frame now has 6,104 EAs or PSUs. Each PSU consists of between 40 and 120 households. The frame was stratified first by region, and then by urban/rural areas within each region. A probability sample of 506 PSUs was selected proportionately across the regions in the first stage using the probability proportional to size sampling procedure together with systematic sampling. Within each region PSUs were selected randomly to achieve the number allocated for that region. Sample size of households was increased to cater for more reliable estimation at the regional level than in previous labour force surveys. At the field level, 8,906 of 9,108 sampled households were visited and interviewed, resulting in 98% coverage.

Mode of data collection

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

The survey instrument for the Namibia Labour Force Survey 2012 was a single questionnaire. The questionnaire collected data on the following:

Part A: Field administrative information
Part B: Household composition and particulars of each household member (relationship to household head, age, citizenship, marital status and receipt of government grants)
Part C: (for all persons 6 and above) Education data (schooling status, highest education level, main language)
Part D: (for all persons 8 and above) Employment data (employment status, work activity, non-wage labour, reasons for not working)
Part E: (for all persons 8 and above) Employment data (industry and occupation, place of work, full/part-time employment, self-employment, employment sector, payment in kind, deductions, work in multiple jobs, job-seeking strategies)
Part F: Working hours
Part G: Employment conditions (employers' social security contributions, employment contracts, income and payment rate
Part H: Employers and the self-employed (registration, business accounts, size of workforce, business turnover)
Part I: (for all persons who had not worked in the previous 7 days) The unemployed (job-seeking strategies, reasons for not working, reasons for not looking for work, rediness to work, length of unemployment, occupation and industry of previous employment, support for the unemployed)
Part J: (administered only to the household head/main respondent) Dwelling type, tenure, main/secondary household income source, total household income (last month), employment of domestic workers)
Part K: (completed by the coder/editor/supervisor) Data collection and data entry control information

Cleaning operations
---------------------------

Data validation included checking for invalid questionnaire numbers, invalid geo-codes, missing data values, incorrect data values, and duplicate questionnaire numbers. Consistency checks involved checking of validated records against logical rules and subsequent editing where necessary. Industies and occupations were also coded during data editing.

摘要
---------------------------
纳米比亚劳动力调查（NLFS）是一项基于家庭的抽样调查。纳米比亚首次劳动力调查于1997年进行，此后每四年由劳工和社会福利部（MoLSW）组织实施一次。NLFS 2012是由2011年成立的独立国家统计机构——纳米比亚统计局——首次实施的劳动力调查。NLFS 2012收集了2012年10月16日至10月27日调查周之前15岁及以上人群的劳动力市场数据。

地理覆盖范围
---------------------------
调查覆盖全国范围。数据地理汇总的最小单位为区域（国家内的13个区域）。

分析单位
---------------------------
调查中的分析单位包括家庭和个人。

调查总体
---------------------------
调查的总体为所有家庭成员。无家可归者和居住在机构中的人群（机构人口）被排除在外。

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

抽样程序
---------------------------
纳米比亚统计局维护的国家抽样框架基于2011年人口和住房普查的计登区和其中的家庭。该框架于2011年7月进行了修订和更新。修订后的框架现在拥有6,104个计登区或PSU。每个PSU包含40至120个家庭。框架首先按区域分层，然后在每个区域内按城乡地区分层。第一阶段采用大小成比例抽样程序和系统抽样，在区域间按比例选取了506个PSU。在每个区域内随机选择PSU以实现分配给该区域的数量。家庭样本量增加，以在区域层面上提供比以往劳动力调查更可靠的估计。在实地层面，访问并采访了9,108个抽样家庭中的8,906个，覆盖率达到了98%。

数据收集方式

研究工具
---------------------------
纳米比亚劳动力调查2012年的调查工具是一份单一问卷。问卷收集了以下方面的数据：

A部分：现场行政信息
B部分：家庭构成和每个家庭成员的详细信息（与户主的关系、年龄、国籍、婚姻状况和政府补助金领取情况）
C部分：（针对6岁及以上所有人员）教育数据（教育状况、最高教育水平、主要语言）
D部分：（针对8岁及以上所有人员）就业数据（就业状况、工作活动、非工资劳动、未工作原因）
E部分：（针对8岁及以上所有人员）就业数据（行业和职业、工作地点、全职/兼职就业、自营职业、就业领域、实物支付、扣除、多重工作、求职策略）
F部分：工作时间
G部分：就业条件（雇主的社会保障贡献、就业合同、收入和支付率）
H部分：雇主和自营职业者（登记、业务账目、劳动力规模、业务收入）
I部分：（针对过去7天内未工作的人员）失业者（求职策略、未工作原因、未寻找工作原因、求职意愿、失业时长、先前就业的行业和职业、对失业者的支持）
J部分：（仅向户主/主要受访者进行）居住类型、租约、主要/次要家庭收入来源、总收入（上个月）、家务工就业情况
K部分：（由编码员/编辑/主管完成）数据收集和数据录入控制信息

数据清理操作
---------------------------
数据验证包括检查无效问卷编号、无效地理编码、缺失数据值、数据值错误以及重复问卷编号。一致性检查涉及验证记录与逻辑规则的核对，并在必要时进行编辑。在数据编辑过程中，也对行业和职业进行了编码。
