Nigeria (Oyo) Round 1 Household and Female (HQFQ) survey a two-stage cluster design. A sample of 80 enumeration areas (EAs) was drawn from the National Population Commission's master sampling frame. In each EA households and private health facilities were listed and mapped, with 35 households randomly selected. Households were surveyed and occupants enumerated. All eligible females age 15 to 49 were contacted and consented for interviews. The final sample included 2,590 households and, 1,875 de facto females. Data collection was conducted between November and December 2017. The Oyo state was not included in the national estimates since the Oyo data collection was done separately and its sampling method differed from those of other states. Thus, data for Oyo state is released separately in a different dataset.
