A large number of young adults, compared with the number of older people: good or bed? It’s crucial for society to keep right balance between different age groups of population. If there are too many children, government cannot provide everyone with adequate education. If there are too many retired people, it’s hard to pay pension for each of them. But what if the population includes more young adults than older people? On the one hand, young adults can be a great resource. They learn faster and are more eager to discover new technologies. It’s estimated that 50 % of current jobs will disappear just in 10 years. Upskilling can be required to everyone who is interested in further career. Older people may be just left behind the society if they used to work on factory or in shop, while younger people are more likely to get new job. On the other hand, greater number of young adults may cause negative consequences. The biggest disadvantage, in my opinion, is that it may be reason for overpopulation. There are more young adults in eastern countries, like China or India, for example, where birth rate is higher than in western countries. Europe, on the contrary, face phenomenon that is called “ageing of population” that means that birth rate is low, so there are more older people than young adults or children. It’s said that by the year 2050 population of the Earth will increase to number 9 billion, and scientists are not sure that our planet will be able to feed its inhabitants. That’s why the government of China imposed laws that forbid having more than one child in a family. Too many young people is an obstacle for this country, because one day there will be simply not enough space for them to live. To sum it up, young adults may play a great role for economical development of the country. However, what is the sense of progress in economy, if the country is overpopulated? I reckon, we should find the balance between different age groups, because this will lead to stable and sustainable development of the country.
