      <serName>Other Household Survey [hh/oth]</serName>
      <serInfo>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.</serInfo>

    <abstract>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.

Further information about the survey, including publications, can be downloaded from the &lt;a href='http://www.younglives.org.uk/'&gt;Young Lives&lt;/a&gt; website.

Constructed Files:
The Rounds 1-3 Constructed Files, 2002-2009 are combined sub-sets of selected variables from Round 1, 2 and 3 of the Young Lives survey. One main constructed data file is available for each of the four countries. These are presented in a panel format and contain approximately 200 original and constructed variables, with the majority comparable across all three rounds.</abstract>
