Household ownership of one (any bed net and LLIN), one LLIN per two persons, and population access to LLIN as measured in four household surveys. Non-SNP Evaluation estimates represent samples in areas with no SNP before the first three surveys (but a mass coverage campaign between survey rounds 2 & 3), while SNP Evaluation Districts estimates represent areas with full SNP rounds implemented prior to each survey. Dashed lines show time periods within the non-SNP evaluation districts prior to roll out of SNP in these districts
