TRANSCRIPT

Key drivers of population change and

population forecasts in NSW

August 2016

.id are population experts (demographers, spatial analysts,

forecasters, urban planners)

.id has Australia’s largest team of population forecasters

We understand how cities are growing and changing

We quantify this knowledge into detailed population

forecasts

Our clients use this knowledge to decide where and when to

invest in infrastructure, services and marketing effort

Over 1.5 million people access .id’s Demographic Resource

Centre every year

We provide the evidence-base for 300 councils Australia-

wide and numerous public and private enterprises

Who are we?

Introducing SAFi

Population growth trends: The Return of the Premier State?

Case study: Anticipating demand at the local level

Questions

Agenda

Population forecasts for New South Wales

Small Area Forecast information

Introducing SAFi

SAFi is a state-wide, micro-geography population forecast

Available for Vic, NSW, ACT & WA.

Provides unprecedented insight into the future of Australia’s population –

macro and the micro level.

Quantifies the demand for services across geographies and over time.

Reflects development activity at a local area level

Regularly updated

Proven over 5 years – third iteration for New South Wales and ACT

What SAFi can tell you?

Population

Dwellings and household types

Single year of age (0-85+ year olds)

Single year of forecast period – 2011 to 2041

Micro-geography – 8,650 SA1-derived areas

Conclusions

The Return of the Premier State

Population growth trends

Sydney is a major attractor of overseas migrants

NSW loses population to other States, especially to Queensland

and to a lesser degree Victoria

NSW is ageing but at a lower rate than expected as overseas

migration and more births have supplemented the population

under 40

Births continue to outweigh deaths, but less natural increase over

time, and more older people

How does NSW’s population grow?

Net overseas migration has increased and the share to NSW has

increased as Western Australia and Queensland have waned

NSW is losing less population to other States, especially

Queensland and Western Australia

NSW has a solid investment pipeline, which is attractive to

migrants given the fall in construction in resource states

NSW has a stable political environment, with a handsome Premier

Fertility rates increased, leading to a greater gain in births

The return of the Premier State…..

Historical Forecast

The final word

Conclusions

There has been a transformation of New South Wales’ population prospects over the

last decade, driven by high rates of overseas migration and higher fertility

Population growth is now likely to be higher and more ‘youthful’ than previously

expected, but the challenge of ageing remains

Growth has continued in established parts of Sydney in the past 5 years and there

are vast numbers of sites in the pipeline

Growth is assumed to hold up in coastal areas in the future

Change is driven by economic factors as well as social components (higher birth

rates / more stable household size

Volatility means timely updates are critical
