Sampling

Sampling Procedure
The Survey is conducted quarterly to produce estimates of employment, unemployment, labour force
participation and basic demographic characteristics. The scope of coverage includes all households in Sri Lanka.

The list of housing units created for Demographic Survey 1994 were taken as sample frame. Sample lists were
selected from the above frame taken as Primary Sampling Unit (PSU). A systematic Sample of 15 housing units per
PSU was selected on final sampling units.

The total annual sample size is 15915 housing units equaly, distributed as 265 PSUs per each quarter and 15 housing
units (SSUs) per PSU. The allocation to the domains aims at ensuring approximately equal of reliability from domain
to domain.

The 1061 PSUs were selected by systematic Sampling from the PSUs created for Demographic Survey - 1994. A listing operation was conducted in each selected PSU to provide a frame for the second stage of selection. The selection of housing units within PSU was
systematic with random start.
Deviations from the Sample Design
The field work of the above survey conducted in 2001 was confined to seven provinces of the country excluding the
Northern and the Eastern provinces

Data Collection Notes
Data are collected quarterly during a similar time period (eg every third week of the quarter) in each quarter through a scientifically selected sample designed to represent the non-institutional household population. About 4000 households are visited each quarter. Respondents are interviewed to obtain information about each member of the household whose age is 10 years or over.

The inquiry relates to the previous calendar week of the interview to obtain "current" information, and to the previous 12 calendar months to obtain "usual" activity information.

[Inmates of institutions, military camps, and lodgings are not surveyed. Households with more than 5 lodgers and boarders were excluded from the survey.]
