Good health directly, and indirectly, improves the wellbeing of individuals and the broader community. For an individual, good health means a life free of the burdens of illness (pain, social isolation, financial costs, and restrictions to lifestyle choices). For the nation, a healthy population is more able to contribute to society in various ways, such as through participation in employment, education and social or community activities. A good level of health also brings about reduced direct costs to the community, both in terms of financial and human capital (such as through lower health care costs and reduced death rates).

Life expectancy at birth is one of the most widely used and internationally recognised indicators of population health. It focuses on the length of life rather than its quality, and provides a useful summary of the general health of the population.

During the decade 2000 to 2010, life expectancy at birth improved for both sexes. A girl born in 2010 could expect to reach 84.0 years of age, while a boy could expect to live to 79.5 years. Over the decade, boys’ life expectancy increased slightly more than girls’ (2.9 compared with 2.0 years). This saw the gap between the sexes’ life expectancy decrease by almost one year to 4.5 years.
