Migration is the component of population change most difficult to measure and estimate reliably hence, the estimation of net migration varies considerably by country. Australia is one of the major net receivers of international migrants (Table 6). Net migration to Australia has been increasing steadily from 1990 to 2010. During 2005-2010, the level of net migration to Australia reached a peak of 10.6 million migrants annually. The movement of people across international boundaries, is very often a response to changing socio-economic, political and environmental factors. On the other hand, levels of migration to Japan is considerably low in 1995-2000. However, in 2010-2015, the level of migration is slightly higher (0.6 million) than had been observed in the past.
Consequence
Slow population growth brought about by reduction in fertility, increase in life expectancy and migration leads to population ageing, that is, it produces populations where the proportion of older persons increases while that of younger persons decreases.
Increases in the median age are indicative of population ageing (Table 7). Generally, Japan and Australia experienced an increasing median age. However, in 2015, the median age of Japan was at its peak (46.3 years). In contrast, the median age of Australia was 37.4, making the population younger than
