Sample design and questionnaire modules. Three of six Nigerian zones, North West, North Central and South South were selected. These zones were chosen based on lower urbanisation rates (excluding the South West and South East) and safety and logistical considerations (excluding North East). Seventy-five enumeration areas (EA) were marked in each zone [total of 225 EAs]. Within each enumeration area, sixteen households and five enterprises were planned to be surveyed. The desired distribution of EAs and the final implementation are shown respectively in Table 4. The surveys cover a wide range of questions regarding demographic and socioeconomic variables, electricity availability and supply quality, appliance ownership and use, available cooking solutions, and capabilities and preferences.
