Life expectancy in Vanuatu is 67 years for men, and 70 years for women. Vanuatu has a tropical climate and over 80% of the population lives in rural, isolated villages with access to their own gardens and food supplies. Malaria is a big problem. Official statistics show infant mortality declined during the last half of the twentieth century, from 123 deaths per 1,000 population in 1967 to 25 per 1,000 in 1999. There were 46.85 infant deaths per 1,000 live births in 2011.
