The Central Reserve Bank of El Salvador is conducting the country’s first National Early Childhood, Childhood and Adolescence Survey, or ENPINA, to produce specialized official statistics on people aged 0 to 17. Supported technically by UNICEF and accompanied by the Ministry of Health, the survey is intended to generate updated evidence on living conditions, health, nutrition, education, protection and development for use in the design, monitoring and evaluation of public policies. About 15,500 urban and rural households across the country’s 14 departments will be visited. Interviews will be conducted with parents, mothers, caregivers, children and adolescents selected through a multistage probabilistic random sample designed to ensure territorial and age-group representativeness. The fieldwork will also include health tests such as weight and height measurements, visual assessments and blood samples, carried out by trained personnel under technical protocols and international standards. Participating families will receive a record of the individual health assessment results for their children for possible medical follow-up.
