At present time the population of some countries includes a relatively large number of young adults compared with the number of old people.

The countries give attention (tend) to the rate of young and old

people

to define the workforce and development of the future. In my opinion, the number of young adults has greater than the number of old

people

has pros

however

it has cons.

Therefore

, I agree with some aspects of it. The

first

, a young person who is the main force to a work and moving for the population in a particular

country

. When the researchers define the economic growth, they consider the percentage of availability to work

people

. One of the reasons, a younger generation pays income tax to the government, and the older generation only gets a pension from the government.

For instance

, the latest developed

country

is South Korea that has involved so many foreign young workers in their own

country

to increase the economy for the

last

20 years.

Finally

, they became one of the highly developed countries.

On the other hand

, the number of young adults is too large, which

also

has cons. For the

country

, when the workforce has been enough, all

people

have a job and making a profit is more difficult.

As a result

, an army without a job became too big .

Furthermore

, they move to the poor ones. Afterwards, they want some subsistence like the older class. In conclusion, young and middle-aged adults are more than aged

people

in a nation, have advantages ,

however

it has disadvantages.

Consequently

, the vision and strategy of that

country

are more important.
