The current project aims to deliver a complementary food supplement (Koko Plus) to infants and young children in three districts in Eastern Ghana. We completed a spatially representative survey, using the Simple Spatial Survey Method (S3M) design, two months into the project with the aim of assessing coverage and barriers to coverage early in the program cycle. The S3M approach allowed for fine scale geographical coverage maps and wide-area population-level estimates to be produced. The data presented here are from an S3M sample with d = 8km (i.e. no person lived more than 8 km from a sampling point). A variable geometry sample design was used. This allowed a mixed urban, peri-urban, and rural sample to be taken with a spatial resolution that matched population density. The sample was taken from m = 58 PSUs spread over three administrative districts. The data reported are for n = 971 mother / child pairs in the sample (n = 671 in the 6 - 24 month target group for consumption of the supplement). Overall 64% (95% CI, 58 - 71%), 23% (95% CI, 19 - 27%), and 15% (95% CI, 12% - 19%) of the target group had ever heard of the supplement, ever used the supplement, and used the supplement at least once in the week prior to the survey respectively. These indicators are mapped in Figure 1. The two main reasons for non-consumption in the target group were caregivers' lack of awareness of the product (61%), and perceived lack of need for the product (14%). These results were reported back to the program within two weeks of survey completion to provide a quick feedback loop to guide programming efforts.
