Generally, from 1990 to 2010, Japan and Australia experienced an increase in total population (Table 1). However, in 2010, the total population of Japan decrease while Australia steadily increases. Demographic transitions contribute to the varying size of population. In turn, this transitions may impact society as a whole. Hence, this essay aims to describe and compare population size of Japan and Australia, in terms of the relationship between the three main demographic processes and its potential impact, drawing primarily upon United Nations population estimates and projections from World Population Prospects: the 2015 Revision.

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.

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
