Total and per capita program costs, 1948–2008.

*The bars reflect real data on expenditure per intervention while the lighter shading is extrapolated based on averages from 1982–1988. Literature indicates a similar allocation of funds, although surveillance-attributed expenditure was probably proportionally higher around 1960 due to a change of strategy with a new focus on surveillance. This figure indicates that the cost of malaria control dropped steadily since 1982, with per capita costs dropping faster than total costs due to growing population size (NB different vertical scales).
