The population is roughly divided into three age-groups, the 0-14 year olds, the 15-64 year olds and the 65+ year olds. The western world is anticipating the number of the over 65's to rise very fast in the future. In Finland the current age-structure is
Finland is probably the first country in the world where the number of over 65's has already surpassed that of the under 15's. The future projections are as follows:
For the sake of comparison the same figures for your country:
Therefore your country is not facing similar imminent problems with an ageing population as Finland is. Even though it is really a demographic miracle to have more over 65's than under 15's Finland is only the frontrunner in that respect as that will be the trend in almost any western country in the years to come. Obviously after some time things will even out but that may well be in the 2060's or some time when todays 0-14's will be over 65's.
This scenario of being overburdened by an army of elderly population is the most common argument in favour of more immigration. That can not however stand a closer scrutiny. If we suppose that a country always imports a number of young immigrants in order to keep the proportion of the elderly at an "acceptable level" that means that the overall population keeps on growing almost exponentially as the immigrants themselves also get older.
One common claim in Finland is that as there have been over 560,000 abortions since 1970, so in 40 years, if all those people had ben allowed to be born, they would themselves have adult children by this time and there would be no talk of a future labour-shortage. On the other hand, just as possible is that if all those over half a million aborted children had been allowed to be born there might have been mass-unemployment and mass-emigration.
One thing about predicting the future population-trends has always been the same and that is that the increase in the average life-expectancy has always been underestimated. Therefore in 2060 there could be even more of the over 65's than predicted as not nearly as many of them have died as has been predicted. Indeed, the estimated life-expectancy in Finland in the year 2060 is 87 years for males and 91 years for females. That seems utopistic today as both numbers are 10 years less today but in 50 years time those figures could even prove to be too short a life-expectancy.
