Population ageing

The world is now facing one unprecedented situation: the population ageing. Basically the people lives longer and the number of children is smaller than before so the global median age of population is slowly and constantly rising. This situation can be found all over the world in almost all countries.

There are just few countries around the world that don’t have this demographic problem. The rest of the world is more or less affected by population ageing. In the developed countries the population ageing is more pronounced while in the less undeveloped countries the population ageing process is not that significant.

At the global level the median age rose from 23.9 in 1950 to 26.8 in 2000, and is expected to be 37.8 in 2050. The figures for the most developed countries group, according to the UN classification, are 29.0 in 1950, 37.3 in 2000, and is predicted to be around 45.5 in 2050.

The population ageing is caused by two factors: the increasing longevity of the adult population and the decreasing fertility which results in a smaller number of children. Unfortunately, for now there is no solution for this problem and is expected that the situation to get worse in the future.

Some countries tried to counteract the ageing of the population through immigration. Canada is a good example of influencing the natural population ageing by increasing the number of young immigrants that this lower the median age of country’s population.

Experts say that this can only solve the problem for short term, because as the fertility rates are still low at some point the immigration will not be able to sustain the same median age level. The immigrants that now lower the median age will get older while the number of new born will get decrease so the number of young immigrants should be increasingly higher which is practically impossible to sustain on long term.
