It is observed that the population of young people in many countries is of a substantial proportion. This comes with arguable advantages and disadvantages. In my opinion, the merits of having considerable number of young populace is beneficial and supersede the demerits.

On an average, young people are physically stronger than the old. This brings about more productivity in the fields they work in. In addition, the young can catch up faster to the technological advancements of the world. For instance, even school children are coming up with latest ideas and innovations in fields like mathematics and science in recent times. Furthermore, a greater number of young people is advantageous in terms of security and defense of a nation. It is also seen that younger generations have higher immunity power and adapt to critical environments quickly. 

However, there are some significant cons of having more young people. The demand for education and jobs is higher and if there is a scarcity of the same, young minds could spiral out of control. For example, people resort to fraudulent ways of making money when they cannot find suitable jobs for themselves. Moreover, lack of quality education could lead to young children having minimal skills. Nevertheless, these issues can be mitigated by implementing proper plans to generate adequate employment opportunities and developing public educational institutions.

To conclude, the developmental changes that young people can engender in a country are on the higher side when compared to the downsides of having pronounced population of the young. In my opinion, the perks of having a greater number of youth takes precedence over the drawbacks.
