Population Health Profile: 2013 The purpose of this Population Health Profile: 2013 is to accurately identify and quantify the local health needs of the resident population of the Illawarra-Shoalhaven Medicare Local (ISML) catchment. It aims to inform the development of focused and responsive primary care services by using a population approach into inter-agency service planning for disease prevention and early intervention initiatives, focusing on targeted population cohorts. This Population Health Profile: 2013 is an inaugural framework document that will be accompanied by supplementary releases containing regularly updated recent data and figures, as and when sourced and adapted from various reliable sources of information. The authors will attempt to keep the Population Health Profile and subsequent Population Health publications current and accurate with all the information required to inform effective and regionally appropriate primary healthcare planning for the Illawarra-Shoalhaven.

Population Health Profile: 2013 1. GEOGRAPHY The Illawarra-Shoalhaven Medicare Local (ISML) covers a large geographic region that extends for 5687.3 square kilometres (sq km) from Helensburgh in the northern Illawarra to North Durras in the southern Shoalhaven1. The Illawarra typically refers to the three Local Government Areas (LGAs) of Wollongong, Shellharbour and Kiama whilst the Shoalhaven consists entirely of the Shoalhaven LGA2. The Commonwealth Territory of Jervis Bay also falls under the catchment area of the ISML. The Wollongong LGA and the Shoalhaven LGA are further divided into two Statistical Local Areas (SLAs) called Wollongong–Inner and Wollongong-Balance and Shoalhaven-Pt A and Shoalhaven-Pt B respectively. For ease of understanding and convenience the ISML catchment will be described using the terminology listed in Table 1. A geographic representation of the Illawarra-Shoalhaven SLAs is shown in Figure 1.

Population Health Profile: 2013 2. DEMOGRAPHY 2.1. Existing population indicators The 2011 estimated resident population of the ISML catchment is shown in Table 2. The Wollongong Inner and the Shellharbour regions are the most densely populated regions within the ISML catchment. Compared to the NSW state population density figure of nine persons/sq km, all ISML regions except Jervis Bay stand higher than the state average. The Shoalhaven Balance region clearly resembles rural population distributions with a density figure of only 14.3 persons/sq km. The Usual Resident Population counts have also been mapped in Figure 2.

Population Health Profile: 2013 The age structure distribution of the population of the ISML catchment as shown in Table 3 and Figure 3 indicates an overall ageing population with 17.6% aged 65 years and above. The Shoalhaven Balance region has a significantly higher proportion of older aged population while Shellharbour and Jervis Bay regions have the highest proportion of school aged children.

Population Health Profile: 2013 Tourism is also a major factor in assessing population especially during the peak holiday periods. 2011 Tourism NSW data indicates that the Shoalhaven and Wollongong areas received the largest number of tourist nights with 3,800,000 and 2,836,000 respectively. With the South Coast standing as the third most visited tourist area within NSW in 2011, the regions of Shoalhaven Balance and the Wollongong Inner were amongst the top three most visited regions of the South Coast. Additionally the Shoalhaven Balance area had the second highest number of tourist nights in NSW. Tourism NSW estimates that Shoalhaven receives 35% of its annual visitor nights or approximately 33,000 visitors per night during the period between Christmas and the end of January. This additional influx of tourist population adds to the health and welfare responsibilities of the regional primary and tertiary healthcare providers. 2.2. Population projections The total population of the Illawarra-Shoalhaven is projected to reach 421,830 in 2021 with the addition of 37,686 more residents. This equates to an average annual growth rate of 0.9% projected per annum. With a projected average annual growth rate of 1.9%, the region of Shoalhaven Balance is expected to have the highest growth in its population followed by the Wollongong Balance region with a 1.2% projected per annum growth from 2011 to 2021.The respective regional population projections for all age groups are shown in Table 4 and Table 5.

Population Health Profile: 2013 2.3. Population diversity and target groups The resident population of the ISML catchment is represented by several diverse population groups. The cultural, ethnic and socio-demographic diversity of the catchment’s population is one of the prime reasons why ISML will use the population health approach to identify local needs and inform the development of focused and responsive primary care services that would holistically cater to all targeted niche groups and populations within the catchment. 2.3.1. Culturally and linguistically diverse (CALD) communities There is a significant proportion of the ISML population that is identified as being of non- English speaking background (NESB). This includes people born overseas in predominantly non-English speaking countries who have migrated to Australia and are currently residing within the ISML catchment (as identified during Census data collections 2011). The percentage of NESB population in the ISML catchment is below the NSW state and Australian national averages. However, with the University of Wollongong and its full services equipped campus at the Shoalhaven area attracting several international students and researchers each year, the numbers in the CALD community are expected to continue rising. In addition, the Illawarra-Shoalhaven is also expected to receive an inflow of a significant number of refugee populations in the coming years. According to the NSW Health Refugee Health Plan3, Wollongong has been one of the prime areas to receive significant numbers of newly arrived refugee and humanitarian entrants seeking initial settlement in rural and regional areas of NSW. Hence ISML healthcare planning aims to be mindful of these circumstances and the impending increase of the NESB population in the catchment. Table 6 shows the figures for the NESB population in the ISML catchment compared to NSW and Australia. Figure 5 maps the concentration distributions of NESB populations in the ISML regions.

Population Health Profile: 2013 Figure 5: Map of culturally and linguistically diverse population, ISML regions, 2011 – percentages of total population A major reason for ISML to focus its population health planning on CALD communities is to improve primary healthcare delivery within the region amongst populations that have been identified as being at a relative disadvantage in terms of accessing quality healthcare. Recent research evidence is suggestive of improved clinical outcomes and patient satisfaction with received care through implementation of language interpretation services for multilingual consumers or persons having limited English language proficiency 4. With a significant number of the ISML catchment population identifying as having poor proficiency at speaking English, ISML population health planning will attempt to seek ways of adopting language interpretation services within general practice to improve community health outcomes and ease service delivery to niche groups. Table 7 below shows the number and percentage of persons with poor proficiency at speaking English in the ISML regions. Page | 13

Indigenous population Indigenous populations form a significant proportion of the ISML catchment. Indigenous refers to persons identified as being of Aboriginal and/or Torres Strait Islander origin as identified by the 2011 Census conducted by the Australian Bureau of Statistics (ABS). 2011 figures identify 3.0% of the ISML catchment population to be of Aboriginal or Torres Strait Islander origin. This is higher than both the NSW state and Australian national averages, both of which are estimated to be 2.5% of the respective populations identified as Indigenous in 2011. The Nowra-Bomaderry region has the highest proportional share of Indigenous population with 7% of its residents identified as Indigenous as per the 2011 ABS Census. While the concentration distribution of Indigenous persons is significantly higher within the Shoalhaven area with 7% of its resident population being Indigenous, the Illawarra region comprising the Wollongong, Kiama and Shellharbour areas has almost 59% of the total Indigenous population of the Illawarra-Shoalhaven catchment. The Shoalhaven area along with the Jervis Bay region account for the rest of the 41% of the Indigenous population of the ISML catchment. Table 8 shows the gross numbers and proportional percentages of the Indigenous population of ISML compared to NSW and Australia. Figure 6 maps the concentration distributions of the Indigenous population in the ISML regions. With a dedicated Closing the Gap team, the Popullation Health initiatives of the Illawarra- Shoalhaven Medicare Local will aim to keep the healthcare needs of the indigenous community of the catchment in the forefront and plan service delivery accordingly.

Population Health Profile: 2013 The age distribution of the Indigenous population in the Illawarra-Shoalhaven differs markedly from the age distribution of the non-Indigenous population. The age bracket of 0- 19 years of age, accounts for almost 49% of the Indigenous population of ISML. Figure 7 below illustrates the wide differences in age structure of Indigenous persons within the Illawarra-Shoalhaven compared to non-Indigenous persons. The marked differences in older ages are primarily due to the differences in life expectancy between Indigenous and non- Indigenous Australians. Figure 7: Age distribution comparison of Indigenous and non-Indigenous population, ISML catchment, 2011 Source: ABS Census 2011 2.3.3. Aged population Australia has long-standing demographic trends of an ageing population and lower birth rates5. With life expectancy figures rising consistently and falling birth rates constantly standing at below replacement levels, Australia’s population is ageing rapidly. This is hence a prime healthcare focus for all health services in Australia and also the rationale for the ISML to focus on the ageing population within the adopted population health approach to primary care planning. In 2011 it was estimated that 17.6% of the ISML catchment population were aged 65 years and above. This is significantly higher than the NSW state average of 14.5% and the Australian national average of 13.8%. Within the ISML catchment the Shoalhaven Balance region has the highest proportion of old aged residents with 26.1% of the population being aged 65 years and above. The Kiama region is placed second with an estimated figure of 20.1% of the population aged 65 years and above. Table 9 shows the proportions of aged population for all ISML regions. Figure 8 maps the concentration distributions of the population aged 65 years and above in the ISML regions. Page | 16

Population Health Profile: 2013 It is also estimated that 64% of the additional projected population of 2021 will be aged 65 years and above. While the population of persons aged 65 years and over in the Illawarra-Shoalhaven is projected to grow at an average annual growth rate of 3.1% till 2021, the Nowra-Bomaderry region is projected to have the highest growth with an overall increase of 50.3% by 2021.

Population Health Profile: 2013 2.3.5. Regional or remote populations Health care services can often be relatively inaccessible for persons residing in regional and remote places. The ISML catchment population structure has been quantified according to the current ‘Remoteness Structure’ as per the Australian Standard Geographical Classification 20066. According to this classification 5 Remoteness Areas (RA) have been formulated where each RA represents an aggregation of non-contiguous geographical areas which share common characteristics of remoteness. The population distribution of ISML indicates a little over 31% of the population being in Inner Regional areas (RA2) and 0.06% residing in Remote areas (RA3). The RA3 sections, even though negligible, belong to the Shoalhaven Balance region. These regional population variations by RA categories are shown in Table 14 below.

Population Health Profile: 2013 3. SOCIO-ECONOMY Socio-economic equity and addressing the disparities of the social determinants of health will be the prime focus of the ISML Population Health approach to primary healthcare planning. Under this methodology, ISML aims to evaluate several measures of socio-economic status of regions in our catchment. One important resource is the Socio-Economic Indexes for Areas (SEIFA) Scores that is prepared by the Australian Bureau of Statistics (ABS)7 by population- weighted averages of scores of Census Collection Districts (CDs) in Australia. The reference value for the whole of Australia is set to 1000. Lower values indicate lower socio-economic status. Table 15 shows the 2011 Index of Relative Socio-Economic Disadvantage SEIFA scores for all regions of the ISML catchment and their national and state rankings in order of being the most socio-economically disadvantaged SLA in Australia, as estimated in 2011.

Population Health Profile: 2013 While research has proven that unemployment is strongly associated with poor physical and mental health,8 9 the health and social impacts of unemployment are reported to be even more catastrophic for children within jobless families. In 2011 it was found that within the Illawarra-Shoalhaven 16.2% of all children below 15 years of age belonged to jobless families, with 15.9% of all jobless families having to support children under the age of 15 years. Apart from the Jervis Bay region, both these indicators were reported to be the highest for the Nowra-Bomaderry region, with the ISML average being higher than both the NSW and Australian averages. Table 17 shows the findings across the region for both these indicators with comparisons across state and national figures. Table 17: Jobless families and children under 15 years of age, ISML regions, 2011 Families Children REGIONS Jobless families % of total families Children under 15 % of total with children with children years in jobless children under 15 under 15 years under 15 years families years JERVIS BAY 15 40.5 45 52.3 KIAMA 145 7.8 259 7.7 SHELLHARBOUR 1,142 15.7 2,181 16.8 NOWRA-BOMADERRY 715 21.2 1,304 21.4 SHOALHAVEN Balance 995 19.4 1,780 19.5 WOLLONGONG Inner 1,345 14.3 2,236 13.9 WOLLONGONG Balance 1,541 15.4 2,825 15.9 ISML Catchment 5,898 15.9 10,630 16.2 New South Wales 100,680 14.1 185,239 14.7 Australia 294,874 13.3 541,792 13.9 Source: PHIDU Social Health Atlas of Australia: Medicare Locals, published 2013 While unemployment figures indicate a significant disadvantage within the population, very low income earners are also at a high level of social disadvantage that ultimately leads to poorer health status. This is also a prime focus for the ISML Population Health approach in order to make primary health care services affordable and accessible for the entire population. While the poverty line benchmark for single adults ranges between $358 to $470.36 per week10 11 depending on the sources and inclusions such as housing, persons with a personal income of below $300 per week have been identified as very low income earners. Table 18 indicates the number of persons earning less than $300 per week (less than $15,600 per annum) and their percentage within the ‘eligible for earning’ total population i.e. persons aged above 15 years of age. The Shoalhaven Balance region has the highest proportion of very low income earners followed by Shellharbour. The Illawarra- Shoalhaven overall has a higher percentage of very low income earners than both the NSW state and Australian national average. This increases the socio-economic disadvantage of the Illawarra-Shoalhaven residents in addition to the existing high unemployment rates across the region as indicated in Table 16. Page | 22

Population Health Profile: 2013 The above illustrated economic indicators lead to wider impacts on several health and social inequalities through various interdependent factors. The most vital ones of these have been grouped in the following themes for the purposes of assisting ISML in designing focused population health strategies. 3.1. Access Access to affordable and responsive transport is a significant problem for many ISML catchment residents. The Illawarra-Shoalhaven geography and a limited public transport system, especially in remote and isolated communities, make it difficult for many people to easily access health services. These issues are heightened in the rural areas, particularly among Indigenous communities. For example, those living at the most southern part of the Shoalhaven need to travel more than 100km to the Shoalhaven District Memorial Hospital in Nowra, and a further 75-80km to Wollongong hospital. 2011 ABS data suggests that 9.1% of households within the Illawarra-Shoalhaven did not have a motor vehicle, with the percentage being highest for the Wollongong Inner region. Access to non-urgent health care services from both outer metropolitan and regional areas is impacted significantly by access to private transport and easily accessible and affordable public transport options. Table 20 shows the numbers and percentages of households with no motor vehicle within the Illawarra-Shoalhaven. ISML will continue to work with the Illawarra-Shoalhaven Local Health District (ISLHD) to seek improvements in the public transport infrastructure in the catchment, addressing the inequities in health access, that occur due to the lack of appropriate public transport, especially for the Shoalhaven area, and the absence of motor vehicle ownership by a segment of the population as shown in Table 20.

ISML aims to investigate solutions to inaccessibility of healthcare through advocating and assisting in uptake of e-health initiatives by primary health care professionals within the catchment. ISML will devote conscious efforts into bringing e-health Page | 24
Population Health Profile: 2013 and telehealth options to populations with limited health access. This is in line with the National Broadband Network (NBN) roll‐out that has already commenced in the Kiama area and parts of Shellharbour and Wollongong, focusing on the delivery of high‐quality NBN‐enabled telehealth services in-home to older Australians with chronic conditions.13 As broadband internet connection allows households to access a vast range of communication tools and offers the potential to improve access to health care through communication solutions, households without any internet connectivity will be a prime focus of ISML’s population health and primary health delivery planning. 2011 ABS data suggests that 23.6% of households across the ISML catchment did not have any form of internet connectivity. This is higher than both the NSW state and Australian national averages. Table 21 shows the numbers and percentages of households with no internet connection within the ISML catchment. The Nowra-Bomaderry region emerges as having the highest percentage of private households with no internet connectivity.

Through the Centrelink program, the Department of Human Services delivers a range of payments and services for such niche population groups such as retirees, the unemployed, families, carers, parents, people with disabilities, Indigenous Australians, and people from diverse cultural and linguistic backgrounds. While these payments are aimed to enable disadvantaged persons to afford and access health and social services; they have always been empirically proven indicators of socio-economic disadvantage34. Table 22 below shows the latest 2011 data on the major population groups receiving any form of income support from Centrelink, and their proportions for all the ISML regions compared with the NSW state and Australian national percentages. Across all the centrelink income recipient groups the Page | 25

The above mentioned indicators play a mojor role in the accessibility and affordability of healthcare services for the significantly high proportion of the ISML population that are affected by these indicators. These findings in addition to the high rates of unemployement in the catchment and the high proportions of low income earning persons and households as identified earlier in this section of the report; present an escalating challenge for primary healthcare planners and service providers to deliver socially and economically equitable primary healthcare to the Illawarra-Shaoalhven community. Furthermore, it is well known that access to timely, effective and cost-efficient healthcare services is also dependent on an individual’s ability to afford private health insurance. Hence, this leads to health insurance being a key indicator of inequality in the community. Table 23 shows the synthetic estimates based on the 2007 ABS National Health survey and indicates much lower coverage rates for ISML compared to the NSW state and Australian national rates. Additionally, the 2009 data for the percentage of health care card holders issued by the Department of Human Services also indicates a high proportion of low income earners aged below 65 years of age in the Illawarra-Shoalhaven who receive Centrelink payments and therefore concessions on health care costs. Table 23 illustrates these indicators across all regions within the Illawarra-Shoalhaven catchment. Page | 26

As shown in Figure 9, 52% of the ISML catchment population is estimated to have Year 10 or less as their highest year of school education, as per the ABS 2011 Census. Figure 9: Highest year of schooling completed, ISML catchment, 2011 Source: ABS Census 2011 Page | 27
Population Health Profile: 2013 Education is of prime importance for young people and is significantly instrumental in building a healthy and prospering community. In 2011 it was estimated that 76.4% of the ISML catchment population aged 15-19 years was enrolled in some kind of education institute, either full-time, part-time or neither but enrolled. It was also estimated that 28.3% of the population aged 15-24 years were enrolled in some form of higher education such as university/other tertiary institution and/or technical/further education institutes (incl. TAFE colleges), while 79.6% of the population aged 15-19 years were learning or earning by being engaged in school, work or further education/training. Table 24 shows the participation in any form of education for persons aged 16 years and for school leavers (majority aged 17 years) along with learning or earning status of 15 to 19 year olds. Given that the University of Wollongong has its major campus in the Wollongong Inner region and that TAFE and other educational avenues are also located in the Wollongong Inner region, the education enrolment percentages are highest for this region, along with Kiama, amongst all other ISML catchment regions. While figures of participation in full-time education at age 16 years is higher for the Illawarra-Shoalhaven than NSW state and Australian averages; the figures for school leavers participation in higher education is very low for the region. Additionally figures are the lowest for the Nowra-Bomaderry region which are estimated to be only 17.2% compared to the Australian national average of 30.4%. The Nowra-Bomaderry region also has the lowest percentage of young adults engaged in some form of learning or earning at ages 15 to 19.

Population Health Profile: 2013 health services is the regional immunisation coverage rates. While the Shoalhaven area has consistently ranked amongst the top 10 regions in NSW (divisions based ranking), the Illawarra has scope to further enhance coverage in the Wollongong, Kiama and Shellharbour areas. With a 91.6% figure for overall coverage, the Shoalhaven ranked 9 th in all NSW divisions as of August 2012, as per initial assessments of the General Practice NSW Immunisation Program conducted by GPNSW. The Illawarra, however, ranked 15th with an overall coverage figure of 90.9%. Figure 10 shows the trends in percentage of full- immunisation coverage for the Illawarra and Shoalhaven compared to the NSW state and Australian national averages. Figure 10: Immunisation coverage* (%), ISML, latest financial quarters 2011-2012 *Initial Counts ONLY. Re-calculations are NOT included. Source: GPNSW, 2012 In addition to immunisation, empirical evidence also suggests that the early years of a child’s life play a major role to play in their future health, development, learning and wellbeing 21. Early childhood development outcomes are considered to be vital markers of the welfare of children, and definite predictors of their future health and well-being. In 2012 the Australian Early Development Index (AEDI) was completed across all regions in Australia for the second time, providing an updated review of the picture of early childhood development outcomes for Australian children. The AEDI measures five key domains of early childhood development: physical health and wellbeing, social competence, emotional maturity, language and cognitive skills (school-based), and communication skills and general knowledge which are assessed through a teacher-completed checklist. Table 25 shows the percentage of children found to be developmentally vulnerable and Table 26 illustrates the proportions of developmental vulnerability on single and multiple domains for school children in the ISML catchment areas compared to NSW state and Australian national figures. While overall the ISML catchment average is lower than NSW state and Australian national averages and, within the catchment the Shellharbour and Shoalhaven community figures reveal the maximum proportions of developmental Page | 29
