Mean Booth Coverage (%) by District and CMC Status, 2008-2009. Each bar represents the mean value for booth coverage during supplemental immunization activities (mass immunization campaigns) in the time period (2008-2009). The value is calculated at the block level separately for CMC areas and non-CMC areas. In this figure the mean values are calculated separately for each District, and separately for CMC areas compared to non-CMC areas. Blue bars represent CMC areas; Orange bars represent non-CMC areas. Booth coverage is the percent of all children living in a block (in either a CMC area or non-CMC area) who are vaccinated at a fixed vaccination post on the first day of the current vaccination campaign.
