Plan research in Equatorial Guinea.

Spanish is the main official and administrative language, while French and Portuguese have official status but narrower daily use. Fang and Bube are important for respondent interviewing, with other local languages by location. Translation should start from Spanish for official review and test oral local-language delivery, especially on Bioko and the mainland.

Bata on the mainland and Malabo on Bioko are the main urban centers, with smaller populations in mainland districts and island communities. National samples need separate Bioko and Rio Muni strata, plus urban-rural allocation. Targeted studies should define whether they cover government, oil-linked, urban consumer or rural community populations.

Mobile phones support respondent contact in urban areas, but online surveys are mostly limited to connected city users. Face-to-face logistics involve island-mainland travel, local permits, rainy seasons and road access outside major towns. Public or health studies commonly require ministry and local administrative clearance. Fieldwork often needs two to four weeks, longer for mixed island-mainland work.
