Development is a process of change that happens over time. It refers to changes in the body of an organism and also to changes in its behavior, interests, needs, etc.
A development pattern or sequence exists in every human being. As an infant learns small words combined with one or two letters and after it he learns large words, the same is true for the habit of sitting and walking and running.
People in developed countries are generally happier and more productive than those in less developed nations. They have better job opportunities, live in better housing, and enjoy better education and healthcare.
Economic growth is another important aspect of development. It leads to higher standards of living and a reduction in inequality.
Inequality is a major problem for many poor nations and it causes resentment, instability, and violence. Inequality also reduces a nation’s ability to generate investment, business confidence and trade.
Resilience is another key aspect of development. More developed countries are more resilient to natural disasters and other crises. They usually rely on external assistance to overcome them, but less developed nations are more vulnerable to natural disasters and they do not have the same mechanisms to meet these challenges.
This is why it is essential for all nations to develop. As they do, they become more stable and less likely to face economic disruptions. They also experience a reduction in crime, conflict and violence. As they develop, they are able to increase their influence worldwide and build strong and sustainable economies.
