Economic Development And Environmental Sustainability

Decent Essays
INTRODUCTION

Changes in the size, composition and distribution of the population are partly a product of prevailing social and economic conditions. Likewise, the structure and size of the population contribute to the shaping of the economy, society and the broader environment.

The future growth, distribution and age structure of the population are key factors underpinning many analyses of long-term policy issues in Australia. Some of these issues relate to service provision, such as health and aged care. Other policy issues include the population aspects of economic development and environmental sustainability (including climate change and water security).

While we cannot know with any certainty what Australia 's future holds in terms of migration, fertility and life expectancy, we can model or project population growth and population change using a range of assumptions. This article illustrates various scenarios.

POPULATION GROWTH

From around 21 million people in 2006, Australia 's population is projected to grow to between 30.9 million (Series C) and 42.5 million (Series A) people in 2056, and to reach between 33.7 million (Series C) and 62.2 million (Series A) in 2101.
