    Abstract

    The National Statistical Office of Mongolia has conducted the Child Labour Survey (CLS) as a module of the Labor Force Survey (LFS) twice using the internationally accepted methodologies. As a result, the Child Labour Survey became a large scale national baseline survey which reflects seasonal variations in the labour market. These surveys also enabled the collection of a wide range of child work data in conformity with the ILO concepts and methodologies and creation of a database on child economic activities, the scope, nature and characteristics of child work. It is needed to augment the statistical information required to develop further strategies on child protection and assess the implementation of programmes and strategies, and to enrich the labour statistics system with child labour data. On the request of the ILO International Programme on the Elimination of Child Labour (IPEC), the National Statistical Office has conducted third Child Labour Survey with financial and technical support of ILO starting from July 2011, for one year.

    Kind of Data

    Sample survey data [ssd]

    Unit of Analysis

    The survey was designed to interview a representative national sample of about 12800 households from Ulaanbaatar and urban and rural areas of 4 regions that was deemed sufficient to collect reliable data on employment and unemployment and child labour. The child labour surveys target group was 5-17 years old population. At this level of disaggregation the sample would be sufficient to produce estimates of high levels of precision in respect of selected child work and labour characteristics. The desired ratio between survey sampling units and households, the survey unit was set up as 12 households and units as 1068. These more detailed sampling techniques enabled to produce estimates of working children by aimags, which was one of main advantages of this survey over the previous survey.
