Other Household Survey [hh/oth]
The Young Lives study is a panel study that aims to track the lives of 2,000 children in each country from age 6-17.9 month until they are 15 years old. The caregiver and, when the child is old enough, both the caregiver and the child will be interviewed every three to four years with a quantitative survey. The height and weight of each child will also be measured and community level questionnaires will be completed for each sentinel site at every data collection round.
Round 1 of the study followed 2,000 children (aged between 6 and 18 months in 2002) and their households, from both urban and rural communities, in each of the four countries (8,000 children in total). Data were also collected on an older cohort of 1,000 children aged 7 to 8 years in each country, in order to provide a basis for comparison with the younger children when they reach that age.
Round 2 of the study returned to the same children who were aged 1-year-old in Round 1 when they were aged approximately 5-years-old, and to the children aged 8-years-old in Round 1 when they were approximately 12-years-old.
Round 3 of the study returned to the same children again when they were aged 7 to 8 years (the same as the older cohort in Round 1) and 14 to 15 years. It is envisaged that subsequent survey waves will take place in 2013 and 2016. Thus the younger children are being tracked from infancy to their mid-teens and the older children through into adulthood, when some will become parents themselves.
Young Lives: An International Study of Childhood Poverty is a collaborative project investigating the changing nature of childhood poverty in selected developing countries. The UK’s Department for International Development (DFID) is funding the first three-year phase of the project.
Young Lives involves collaboration between Non Governmental Organisations (NGOs) and the academic sector. In the UK, the project is being run by Save the Children-UK together with an academic consortium that comprises the University of Reading, London School of Hygiene and Tropical Medicine, South Bank University, the Institute of Development Studies at Sussex University and the South African Medical Research Council.
The study is being conducted in Ethiopia, India (in Andhra Pradesh), Peru and Vietnam. These countries were selected because they reflect a range of cultural, geographical and social contexts and experience differing issues facing the developing world; high debt burden, emergence from conflict, and vulnerability to environmental conditions such as drought and flood.
Objectives of the study
The Young Lives study has three broad objectives:
• producing good quality panel data about the changing nature of the lives of children in poverty.
• trace linkages between key policy changes and child poverty
• informing and responding to the needs of policy makers, planners and other stakeholders
There will also be a strong education and media element, both in the countries where the project takes place, and in the UK.
The study takes a broad approach to child poverty, exploring not only household economic indicators such as assets and wealth, but also child centred poverty measures such as the child’s physical and mental health, growth, development and education. These child centred measures are age specific so the information collected by the study will change as the children get older.

Version
Edition History:
-
For the original edition of the study (February 2006), data and documentation from Wave 1 were deposited.
-
For the second edition (February 2009), data and documentation for Round 1 were updated, and data and documentation for Round 2 were added to the study.
-
For the third edition (August 2009), two of the Peru data files were updated. Firstly, a new version of file 'PEChildLevel5YrOld', which includes corrections to variables language1, language2, source, score_ppvt, score_cog, rscore_cog, and rscorelang_ppvt. Secondly, a new version of file 'PEChildQuest12YrOld', which includes corrections to variables language1, language2, source, score_ppvt, rscorelang_ppvt, score_math, and rscorelang_math. Users are advised to download the new versions of these files.
-
For the fourth edition (September 2011), the Round 1 household and child surveys data files have been updated. The Round 1 community data files and documentation have also been added.
-
For the fifth edition (April 2014), the data files and accompanying data have been updated. The updates have been made as a result of ongoing cleaning associated with the collection of longitudinal data (i.e. checking the consistency of the data across rounds). Extensive work has also been done on updating the location variables of the children and a new variable has been added to the Round 2 (MVDTYPR2) and Round 3 (MVDTYPR3) data (see SNs 6852 and 6853 respectively) indicating if the child has moved between rounds. Updated PPVT scores and calculated variables have also been provided. A full edition history is contained in the READ file.
Scope
The study include the following topics: community characteristics (environmental, social and economic); household composition; child health; caregiver background; livelihoods; economic changes; socio-economic status; social capital and anthropometry. In addition, the information gathered for younger children also includes details from the caregiver on pregnancy, delivery, breastfeeding, mental health, and child care. Topics specific to the older 8-year-olds survey include child's schooling and work; child mental health (not available for Peru or Ethiopia), and child development.

Sampling
Purposive selection/case studies
A key need for the study's objectives was to obtain data at different levels - the children, their households, the community in which they resided, as well as at regional and national levels. This need thus determined that children should be selected in geographic clusters rather than randomly selected across the country. There was, however, a much more important reason for recruiting children in clusters - the sites are also intended to provide suitable settings for a range of complementary thematic studies. For example, one or a few sites may be used for a qualitative study designed to achieve a deeper level of understanding of some social issues, either because they are important in that particular place, or because the sites are appropriate locales to investigate a more general concern. The quantitative panel study is seen as the foundation upon which a coherent and interesting range of linked studies can be set up.
Thus the design was decided, in each country, comprising 20 geographic clusters with 100 children sampled in each cluster.
For details on sample design, see the methodological document which is available in the documentation.
