The JSLC is conducted annually by the Statistical Institute of Jamaica (STATIN) on a rotating panel of approximately 2000 households. This survey has been implemented without interruption since 1988. However, in 2003, a abridged version of the questionnaire containing consumption expenditure and basic houshold characteristics only was fielded. Since then, the full survey is fielded biannually. The main objective of the survey is to monitor the social conditions of the Jamaican populace.
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.

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
Refusals 5.7% Vacant/closed dwellings 26.1% Total non-response - 31.8%
The survey used three different weights which fulfilled different functions. The first weight accounts for the adjustment for non-response biases. The second weight is applied to compensate for the changes in the number of dwellings that occurred between the time of the Census and the time of the listing. The final weight is a post-stratification weight that is applied to control the population total for each parish. Population totals of the number of persons by the demographic variables age and sex at the parish level were estimated primarily from the last population census.
Dates of Data Collection
Data Collection Mode
Overall coordination at national level with a minimum of one supervisor per parish. The JSLC statisticians visit all the supervisors’ zones during the early part of the fieldwork and scrutinize a number of questionnaires completed by each interviewer and checked by the responsible supervisor. On-the-job training, corrections, etc are done as necessary.
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.
The consumption expenditure data collected i were then annualised. At this stage, four indicators are adopted for cleaning the data, namely: (i) per capita annual household consumption expenditure; (ii) the percentage expenditure on Food group; (iii) the percentage expenditure on Meals taken away from home; and (iv) the percentage expenditure on Housing. These indicator values were calculated for all households along with the corresponding mean and standard deviation. This operation was carried out for households falling into each of the five per capita consumption expenditure quintiles formed on the basis of indicator (i) for ensuring an adequate completion of the cleaning process. Questionnaires of households which fell beyond the range "mean plus or minus two standard deviations" for any of the four indicators were taken from each of the quintiles for further scrutiny. A total of 6 513 questionnaires were accepted for the final data set.
