The 2011 Survey on Children (SOC) is a nationwide survey designed to collect data on the demographic and socio-economic characteristics of working children 5 to 17 years old. The survey is a joint collaboration between the International Labour Organization (ILO) and the National Statistics Office (NSO) as part of the International Programme on the Elimination of Child Labour (ILO-IPEC).
As rider to the October 2011 Labor Force Survey (LFS), the 2011 SOC covered about 50,000 sample households using the NSO 2003 Master Sample Design with the 17 administrative regions as domains. The regional groupings were classified in accordance with Executive Order No. 103 (May 17, 2002) which divide Region IV (formerly Southern Tagalog) into Region IVA (MIMAROPA) and Region IVB (CALABARZON), and Executive Order No. 36 (September 19, 2001) for the Administrative Regions in Mindanao.
The 2011 SOC used the population projections based on the 2000 Census of Population to conform with the known population. The revised 1994 Philippine Standard Occupation Code (PSOC) was used in classifying the occupation of the working children, while the revised 1992 Philippine Standard Industry Code (PSIC), in classifying the industry.
The survey involves the collection of data through personal interviews with the household as the reporting unit. This means that the statistics emanating from the survey refer to the characteristics of the population residing in private households. In this survey, the ultimate sampling unit was the child worker 5 to 17 years old.
"Child labor" in this survey refers to the working children who reported to have worked in hazardous environment regardless of the number of hours they spent at work (Hazardous Child Labor), or those who have worked for long hours (more than 20 hours a week for children 5 to 14 years old and more than 40 hours a week for children 15 to 17 years old) or "Other Child Labor." The rest of the working children are classified under "Not Child Labor" category.
Hazardous labor involves exposure to environmental hazards such as physical hazards (e.g. noise, temperature or humidity, slip, trip of fall hazards, etc.), chemical hazards (e.g. dust, mist, fumes or vapor, liquid, etc.) and biological hazards (e.g. bacterial, fungal, viral, parasitic, etc.)
The 2011 SOC questionnaire used a more comprehensive set of questions to catch the incidence of child workers. Aside from the main screening question, seven other screening questions were introduced.
