Regional areas such as Dorset and Break O'Day are at the most risk of population drain, with natural decline positioning them in a near irreversible state of depopulation, a new report has warned.

However, a population strategy adopted by the state government in 2015 does not have specific provisions for population increases in regional areas.
University of Tasmania demographer Lisa Denny, who collaborated on the report said regional and "sub-state" areas in Tasmania would bear the brunt of population decline if nothing was done.
Tasmania's population strategy has the bold target of increasing the state's population to 650,000 by 2050.

The strategy aims to increase population through migration and jobs creation activities. However, there are no incentives to encourage people to settle in regional areas.
State Growth Minister Peter Gutwein said the government was committed to sustainably growing the population to its 2050 target.
"Up to September 2018, Tasmania's population grew by 1.15 per cent to 529,903. This exceeds the annual growth rate of 0.66 per cent required from 2014 to achieve our population target," he said.
"Tasmania now has the strongest growing economy in the nation for the first time in almost 15 years, and we have a budget that will maintain the momentum and invest for growth."
Ms Denny and fellow researcher Nyree Pisanu made four recommendations in the report, which they said would help to arrest the threat of population decline.
The recommendations urged a holistic approach to halt population decline and urged all levels of government to work together to implement improved policy direction.
"Sub-state demographic change typically accelerates structural ageing - that is, young, working-age people leave the area, making the area's population proportionately older," the report read.
"The short-term drivers of demographic change include economic cycles or shocks, policy decisions and changing spatial patterns. Longer-term drivers are demographic trends and globalisation."
Dorset was listed in the report to be in "absolute decline" and other smaller regions such as Break O'Day, Glamorgan Spring Bay, and Flinders were also in decline.
"The tipping point for sustained population decline is considered to be when an area reaches the onset of natural decline (which is when the rate of decline is not overtaken by migration).
"The reality is that population ageing and an age-driven end to population growth is unavoidable. The implications for planning and policy are serious and urgent; responses must take a short, medium and long-term view."
