Abstract
A survey module was attached to Sri Lanka Labour Force Survey (LFS) 2014 to collect data on health conditions of people in the country.
This health survey was conducted at household level and self-reported (without medical tests or clinical proofs) health
associated data was collected from all individuals of the selected households.
The statistics estimated through the survey will be immensely useful for the government, policy makers to plan health services, especially for resource allocation, for preventive actions and to provide clinical care. The survey covers all districts of the country therefore statistics will be published at district level. Since all the data collected in the health module are self-reported, the facts are based on the level of awareness of the respondent. Further this is the first ever island-wide household survey on health and this was conducted during 12 months period in 2014.
a. Subjects covered at the survey:
1. Prevalence by type of illness – chronic/ acute

Sampling
Sampling Procedure
Sampling plan and the sampling frame
Two stage stratified sampling procedure is adopted to select a sample of 25,000 housing units to be enumerated at the survey. The master sampling frame prepared for 2011 - Census of Population and Housing is used as the sampling frame for the sample selection of LFS in 2014.
Sample size
Annual sample of 25,000 housing units were selected to give reliable estimates by district level in the year 2014.
Sample Allocation
In 2014, 2500 Primary sampling Units (PSU's) were allocated to each district and to each sector (Urban, Rural and Estate) by using the Neymann allocation method which considers the variance of unemployment rate as usually (because the sampling of the health survey is the same as LFS) The allocated sample for each district then equally distributed for 12 months.
Selection of Primary Sampling Units (PSU)
Primary sampling units were the census blocks demarcated at the Census of Populationand Housing - 2011.
Selection of Secondary Sampling Units (SSU)
Secondary Sampling Units were the housing units in the selected 2500 primary sampling units (census blocks). From each selected primary sampling unit, 10 housing units (SSU) were selected for the survey using systematic random sampling method.
