2.3.3. Socioeconomic Status and Family Information

Socioeconomic status (SES) variables included wealth index and maternal education, which were assessed using Demographic & Health Survey (DHS) items standardized for each country [18]. The wealth index comprised 21 items as recommended for multiple assets analysis (water source, fuel use, assets, transportation, animals owned, toilet facilities etc.). Information on the stimulation and learning opportunities offered by the child's home environment was collected with the family care indicators (FCI) [19] items included in the UNICEF Multiple Indicators Cluster Survey.
