A total of 60 per cent of the worlds preterm births are found in only 10 countries, 6 of which are in the Asian and Pacific region: Bangladesh; China; India; Indonesia; Pakistan; and the Philippines. The countries in the region with the highest preterm birth rates in 2010 were Pakistan (16 per 100 live births), Indonesia (15 per 100 live births), the Philippines (15 per 100 live births), Bangladesh (14 per 100 live births) and Nepal (14 per 100 live births). Estimates of this indicator are produced from data collected from such surveys as demographic and health surveys and multiple indicator cluster surveys. Interpretation should therefore be considered with caution.
