Coverage adjustment/estimation/Coverage Assessment and Adjustment (CAA)

Coverage adjustment is the process of combining the results of the census and information gathered via a follow up survey (the Census Coverage Survey) to make a reliable estimate of those not counted in the main census. It also accounts for bias in non-response and overcount within the population. This allows a highly precise estimate of the total resident population to be made. This approach is internationally recognised. More information about this can be found in our Methodology section.
