Change over time in national average of DTP3 coverage among children aged 12–23 months, and in quintile 1 compared with quintile 5, in 21 low-income and middle-income countries

Data taken from DHS and MICS 2000–03 and 2010–13. Every country is represented by a shape, which corresponds to its WHO region. For every study country, the annual absolute change in national average was calculated by subtracting the national coverage in survey year 1 (2000–03) from coverage in survey year 2 (2010–13) and dividing by the number of intervening years. The annual absolute excess change was calculated by subtracting the annual absolute change in quintile 5 from the annual absolute change in quintile 1. Red and blue boxes portray undesirable and desirable scenarios, respectively. DHS=Demographic and Health Survey. DTP3=three doses of the combined diphtheria, tetanus toxoid, and pertussis vaccine. MICS=Multiple Indicator Cluster Survey.
