Most of the geographical area is served by Counties Manukau Health (CMDHB) is part of the territorial authority (TA) of Auckland Council. However, small areas of the southern extent of the DHB are part of Waikato District and Hauraki District territorial authorities.
- The estimated Counties Manukau population for 2016 is 534,750, 11% of the total New Zealand population.
- DHB planning is based on estimated resident population projections and sociodemographic information from the latest Census – as of January 2016 projections based on Census 2013. Health service utilisation information is also used to inform service planning.
- The link below is updated annually with population projections from Statistics New Zealand, produced, specifically for the Ministry of Health with prioritised ethnicity as used in the health sector.

Population demography and needs
- A range of documents provide information on the demography and health needs of the people of Counties Manukau available on the Health status documents page. Information is also available in various Counties Manukau Health Planning documents.
- For the purposes of service planning and integration, the area served by CM Health is divided into four localities – Mangere/Otara, Eastern, Manukau and Franklin.
- Within each locality, there are two populations of note in relation to planning – the people who live in the locality and the people who are enrolled in primary care practices in the locality. These two populations overlap but are not the same and the variance differs across the localities.
- There is information specific to each locality across the Counties Manukau District available under the Localities planning page.
- The population of Counties Manukau is multiethnic with high numbers and proportions of Maaori*, Pacific and Asian peoples (see table below).
- Ethnicity mix of the CM population varies by age, with younger groups having higher proportions of Maaori*, Pacific and Asian peoples than the population aged 65 years and over (where two thirds of the population are NZ European/Other groups).
- Within the area served by CM Health, the four localities have quite distinct mixes of these different population groups. While all areas have people from most ethnic groups, based on the distribution at the time of Census 2013, a high proportion of Pacific peoples live in Mangere/Otara, Maaori in Manukau (particularly Manurewa and Papakura), the Indian population in Manukau, Chinese and Other Asian groups in Eastern and NZ European/Other groups in Eastern and Franklin localities.
- While our population is aging, Counties Manukau still has a higher proportion of children than the overall NZ population. Twenty-three percent of the population is aged 14 or under (123,400 in 2016); 13% of New Zealand children aged 14 or under live in Counties Manukau.
- Fertility rates in New Zealand have been reducing in the last decade and particularly in the last three-four years. Counties Manukau has a high birth rate compared with many other areas. This contributes to relatively high demand on our maternity, child and youth health services. However birth rates in Counties Manukau have also decreased in recent years, particularly among young, Maaori and Pacific women.
- The Counties Manukau population is growing at 1-2% per year, an additional 8-9,000 residents each year on average. This rapid growth mirrors growth in the metro-Auckland region, and places a significant load on health service provision.
- The population aged 65 and over is growing at 4-5% per year and projected to increase by over 14,000 people from 57,720 people in 2015 to just under 71,000 by 2020. This group are high users of health services.
- At the time of the 2013 Census 36% of the Counties Manukau population were living in areas classed as the most socioeconomically deprived (based on the NZ Deprivation Index 2013, deciles 9 and 10 being the 20% relatively most deprived areas in New Zealand). Applied to the estimated population for 2016, this would equate to 192,510 people living in areas of high socioeconomic deprivation.
- Maaori* and Pacific residents and children of Counties Manukau were concentrated in decile 9 and 10 areas – 58% of all Counties Manukau Maaori*, 76% of Counties Manukau Pacific peoples, and 45% of the 0-14 years old in Counties Manukau were living in decile 9 and 10 areas at the time of Census 2013.
- The high proportion of the Counties Manukau population living in socioeconomic deprivation has a significant impact on health and health service provision. For example, Counties Manukau has a high rate of illnesses linked to overcrowded and poor quality housing. The avoidable mortality and hospitalisation rates for the Counties Manukau population are higher than the national rates, with Maaori* and Pacific residents having higher rates than those in Asian and NZ European/Other groups.
- In addition, conditions related to smoking, obesity, poor nutrition, lack of physical activity, misuse of alcohol and other health issues are more prevalent for people living in poverty. Work to address poverty and to make social and physical environments more supportive of healthy living is important to help address these issues.
