Life expectancy at birth in males (years) 2004 WHOSIS
Life expectancy at birth in females (years) 2004 WHOSIS
Under-5 mortality rate (per 1 000 live births) 2004 WHOSIS
Infant mortality rate (per 1 000 live births) 2004 WHOSIS
% DPT3 immunization coverage among 1-year-olds 2004 WHOSIS
Per capita GNI (in PPP international dollars) 2004a WHOSIS if availableb
Natural log of per capita GNI (in PPP international dollars) 2004a WHOSIS if availableb
% urban population 2005 WHOSIS

DTP3, third dose of diphtheria–tetanus–pertussis vaccine; GNI, gross national income; log, logarithm; PPP, purchasing power parity; WHO, World Health Organization; WHOSIS, WHO Statistical Information System.

a The year closest to 2004 was used if 2004 estimates were unavailable.

b When WHOSIS data were not available, we used corresponding estimates from The world factbook.13 The data collected from the The world factbook were actually the gross domestic products (in PPP international dollars). Other sources reporting GNI (in PPP international dollars), such as The World Bank, contained the same missing values as the WHOSIS.14
