What is the demographic transition?Show answer
The demographic transition model explains how populations move from high birth and death rates to low ones through stages:
What is internal migration?Show answer
Internal migration redistributes people within a country, dominated historically by rural-to-urban movement as industrial and service jobs concentrated in cities. China's reform-era movement of hundreds of millions from rural interior to coastal industrial cities is the largest internal migration in history. In Australia, internal migration includes the long drift from rural and inland areas to coastal cities, plus more recent "sea change" and "tree change" movements to regional coasts and towns, accelerated by remote work.
What is international migration?Show answer
International migration redistributes people between countries, driven by push factors (poverty, conflict, persecution, disaster) and pull factors (jobs, safety, family, opportunity). Major historical and modern flows include:
What are twenty-first century projections?Show answer
Projections suggest world population peaking and then plateauing or declining later this century as fertility falls almost everywhere. The growth that remains is concentrated in sub-Saharan Africa, while East Asia and Europe age and shrink. Australia's population is projected to keep growing, but mainly through migration rather than natural increase, because the national fertility rate is below replacement.
