Child Labor Survey [hh/cls]
The International Programme for the Elimination of Child Labour (IPEC), functioning under International Labour Organization (ILO), decided to collect information required for their action plan, through a household based survey. The Department of Census & Statistics was entrusted with the implementation of the survey in Sri Lanka.
The Child Activity Survey was conducted in 1990 by using a sample of 14,400 housing units, representing the whole country except for Northern and Eastern provinces. The questionnaire was so designed to collect information on economic activities, housekeeping activities and other leisure activities, in which the children in the age group 5-17 years are involved.
Additional information on socio-economic conditions of their families was also collected at this survey.
Child Activity Survey was designed to measure the economic activities and also other activities such as leisure, education and housekeeping activities in which average Sri Lankan child is involved.
Key objectives of the survey
- To identify the activity status of children
- To identify the health and safety of the working children
- To identify the perceptions of the parents/guardians of the working child
- To identify the labour force information of all persons of age 10 yrs. and over belonging to the household.
- To identify the housing conditions and family income of the household
Sample survey data [ssd]
- Child aged between 5 and 17 yrs
- Household where the child lives

Sampling
Sampling Plan
A two stage stratified sampling procedure was adopted to select an ultimate sample of 14,400 housing units ( secondary sampling units ) to be enumerated in the survey as described below.
Sample Frame
The master sampling frame prepared for the Demographic Survey - 1994 was used as the sampling frame for the selection of sample for the Child Activity Survey - 1999. This sampling frame consists of about 4000 primary sampling units (PSU's) and out of this 4000 PSU's, 960 PSU's were selected using probability proportionate to size (pps) method, to be enumerated in the Child Activity Survey. The PSU's were formed such that the housing units located in the PSU's can be identified within the clearly defined physical boundaries of the PSU. The known selection probabilities associated with each PSU in the master sampling frame prepared in 1994 were adjusted to get the selection probabilities of the PSU's selected in the Child Activity Survey - 1999 sample.
Stratification
The survey was conducted in areas excluding Northern & Eastern provinces of Sri Lanka. (There are 9 such provinces altogether in Sri Lanka). Each province consists of 2 or more administrative sub-divisions called Districts. The area in which the survey was to be conducted was stratified by district and sector of residence (urban & rural) thus forming 34 strata. (There are 17 districts in the 7 provinces where the survey was conducted).
Allocation of Primary Sampling Units (PSU's)
Primary Sampling Units (PSU's) were allocated among the strata by using proportionate allocation. (i.e. proportionate to the number of housing units in each stratum). After allocating the sample, the selection of the PSU's was done using a probability proportionate to size method. (Size being the number of housing units in each stratum).
Selection of Secondary Sampling Units (SSU's)
Lists of housing units, as prepared for Demographic Survey - 1994, were available for all the PSU's in the master sampling frame and those lists of the PSU's selected for the Child Activity Survey were updated prior to the survey.
A systematic sample of 15 housing units was selected as secondary sampling units or SSU's from the updated lists of housing units of each PSU selected in the sample. The distribution of 14,400 ultimate SSU's (housing units) so selected is given in the following table.
The field work of the survey conducted in year 1999 was confined to seven provinces of the country excluding the Northern and the Eastern provinces (due to the prevailing situation in the above two provinces).
Response Rate is 93.7%
Survey instrument
The questionnaire was designed to collect information on
economic activities
housekeeping activities and
other leisure activities in which the children in the age group 5-17 years are involved. Additional information on socio-economic conditions of their families was also collected at the survey.

Survey field work was done in four rounds during the period from November 1998 to June 1999. Eight teams, each team consisting of 5 enumerators and a supervisor, were employed in the survey field enumeration.
A four day training programme was organized to train the enumerators and supervisors in different aspects of the survey enumeration prior to the survey. This training programme was also attended by ILO & IPEC representatives. While the survey teams were in field, they were frequently visited by coordinators to evaluate the field conditions and also to liaise with the head office. These visits also helped the survey teams to get their problems addressed properly.
As it can be seen in the questionnaire, it would have been best if the children themselves were interviewed to obtain the required information under section 2 and 3 of the questionnaire. However the experience of the survey teams was that the children were mostly not available during the time of the interviews and required information had to be obtained from a proxy respondent. ( very frequently from a parent of the child).
When a selected sample housing unit was temporarily closed at the time of the survey, the survey team was expected to re-visit the same housing unit, even several times, with the view of getting a better response. Survey teams got a very good co-operation from the respondents (children and their parents) as regards the information collected. This was so because the questionnaire was not just confined to economic activities of the children.
The questionnaire was so designed to get the information on educational, leisure and housekeeping activities of the children prior to the information on economic activities and this sequential order of the questions helped very much for the survey enumerators to get the co-operation of the respondent.
However the reliability of the information provided by the respondents as to the duration of time spent on each activity is questionable, specially when the involvement of the child in a particular activity is very minimal.
Data processing
When the completed questionnaires are received at the head office, the questionnaires were subject to a manual editing and coding operation at the Sample Survey Division of the DCS.
