Passage: The 2013 New Zealand census enumerated a resident population of 4,242,048, an increase of 5.3% over the 2006 figure. As of June 2019, the total population has risen to an estimated 4,968,960. In 2018 the median age of the New Zealand population was 38.1 years.New Zealand is a predominantly urban country, with 73.0% of the population living in the seventeen main urban areas (i.e. population 30,000 or greater) and 55.1% living in the four largest cities of Auckland, Christchurch, Wellington, and Hamilton. New Zealand cities generally rank highly on international livability measures. For instance, in 2016 Auckland was ranked the world's third most liveable city and Wellington the twelfth by the Mercer Quality of Living Survey.Life expectancy for New Zealanders in 2012 was 84 years for females, and 80.2 years for males. Life expectancy at birth is forecast to increase from 80 years to 85 years in 2050 and infant mortality is expected to decline. New Zealand's fertility rate of 2.1 is relatively high for a developed country, and natural births account for a significant proportion of population growth. Consequently, the country has a young population compared to most industrialised nations, with 20% of New Zealanders being 14 years old or younger. By 2050 the median age is projected to rise from 36 years to 43 years and the percentage of people 60 years of age and older to rise from 18% to 29%. In 2008, the leading cause of premature death was cancer, at 29.8%, followed by ischaemic heart disease, 19.7%, and then cerebrovascular disease, 9.2%. As of 2016, total expenditure on health care (including private sector spending) is 9.2% of GDP.
