Survey of Living Conditions 2008 - Jamaica

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

The JSLC gleans household and individual data from a subset of the population covered by the Labour force Survey. Information is collected on consumption, health, education, nutrition, housing, demographic characteristics, and the Food Stamp Programme. The main purpose of the survey is to provide the government with information for policy development and planning. Although modeled of the World Bank's Living Standards Measurement Study (LSMS) household surveys, it has a narrower focus and greater emphasis on policy impact. In 2008, a large survey was done to allow for data disaggregation at a parish level. It also included modules on Early Childhood Development and Adult Literary.

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

Sample survey data [ssd]

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

The sample dwellings for the JSLC is is the same as the preceding Labour Force survey (LFS) to facilitate linkage of the data from both surveys. The sampling design is a two-stage stratified random sampling with the first stage being the selection of areas (enumeration districts (ED)) and the second stage a selection of dwellings. For the selection of EDs all in the country are grouped into Sampling Regions (SR) of strata of approximate equal size, in terms of the number odf dwellings. Two EDs are selected from each sampling region with probability proportionate to size. In each ED, a list of dwellings is prepared and this becomes the frame for the selection of the Master Sample of dwellings for the labour force. Sample size: planned 9,623 actual 6,513

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

Face-to-face [f2f]

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

Structured questionnaire

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

Before data entry, all the questionnaires are edited and coded. All questionnaires partially completed, or not properly filled out, were removed from data entry operations if they could not be corrected. The questionnaires were then screened by the supervising Statisticians, before being submitted for data entry. The data entry for JSLC 2008 was done on personal computers and adequate computer checks for ensuring consistency in totals, codes, etc, which are feasible at this stage were introduced in the programme. The computer printouts of the data in respect of a sample of households from all supervisory zones were then compared with the individual questionnaires to try and identify data entry errors by the assistants and JSLC statisticians. Also, a 10 per cent sample of the questionnaires was double entered, in an effort to check for errors by data entry operators. The SAS software was used for all electronic processing.

Response rate
---------------------------

Refusals 5.7% Vacant/closed dwellings 26.1% Total non-response - 31.8%

These are done and recorded in the report

摘要
---------------------------
JSLC（加勒比家庭与个人调查）从劳动力调查的一部分受调查人口中收集家庭和个人数据。调查收集的信息包括消费、健康、教育、营养、住房和人口统计特征，以及食物券计划。该调查的主要目的是为政府提供政策制定和规划的信息。尽管该调查以世界银行的生活水平测量研究（LSMS）家庭调查为模型，但它的关注点更窄，对政策影响的重视程度更高。2008年进行了一次大规模调查，以便在教区层面上进行数据细分。调查还包括了关于早期儿童发展和成人文学的模块。

样本调查数据 [ssd]
抽样程序
---------------------------
JSLC的样本住宅与先前的劳动力调查（LFS）相同，以便于两个调查数据的连接。抽样设计为两阶段分层随机抽样，第一阶段是选择区域（统计区（ED）），第二阶段是选择住宅。在抽样中，所有国家都分为大小大致相等的抽样区域（SR）层。从每个抽样区域中随机选择两个ED，其概率与规模成比例。在每个ED中，准备一份住宅清单，该清单成为选择劳动力调查主样本住宅的框架。样本量：计划9,623，实际6,513

研究工具

结构化问卷
清理操作
---------------------------
在数据录入之前，所有问卷都经过编辑和编码。所有部分完成的或未正确填写的问卷，如果无法纠正，则从数据录入操作中移除。问卷随后由监督统计学家进行筛选，然后再提交数据录入。2008年JSLC的数据录入是在个人计算机上进行的，并引入了足够的计算机检查以确保总数、代码等的一致性，这在当前阶段是可行的。随后，将来自所有监督区域样本家庭的计算机打印数据与个别问卷进行比较，以尝试识别助手和JSLC统计学家在数据录入过程中可能出现的错误。此外，10%的问卷进行了双重录入，以检查数据录入操作员可能出现的错误。所有电子处理均使用SAS软件。
应答率
---------------------------
拒绝率 5.7%，空置/关闭住宅 26.1%，总非应答率 - 31.8%
