Nigeria (Kaduna & Lagos) Round 2 Service Delivery Point (SQ) survey used a three-stage cluster design, with urban-rural as strata in Kaduna. A sample of 60 clusters of enumeration areas (EAs) in Kaduna and 51 clusters enumeration areas (EAs) in the urban stratum in Lagos were drawn from the National Population Commission's master sampling frame along with a list of EAs contiguous to the index EA. The EAs in Nigeria are usually small, with approximately 48 households on average. To create clusters with a minimum of 200 households, each index EA was listed and mapped.  If there were fewer than 200 households identified, the next EA in the list of contiguous EAs was listed and mapped in its entirety.  If the total number of households was still less than 200, the entirety of the third EA was listed and so on.  Each cluster of EAs serves as the primary sampling unit from which 35 households (40 in Lagos) and up to 3 private health facilities were randomly selected.  Public facilities were included if a selected EA fell within the catchment area. Private facilities were included if they fell within the boundaries of the EA. The final sample included 154 SDPs in Kaduna and 123 SDPs in Lagos. Data collection was conducted between August and September 2015.
