Which of the following best defines 'economic growth'?

Economic growth is best defined as an increase in the production capacity of the economy. This means that the economy can produce more goods and services over time, which is often measured by the rise in Gross Domestic Product (GDP). When an economy grows, it indicates that it is becoming more efficient and capable of meeting the needs and wants of its people.

This increase in production capacity can result from various factors such as improvements in technology, increases in the labor force, or investment in capital goods. When production capacity rises, it typically leads to higher employment opportunities, better incomes, and improved living standards, showing the broad benefits of economic growth.

While other choices refer to different economic concepts, they do not accurately capture the essence of economic growth. A decline in government spending and a reduction in imports can impact economic performance but do not directly indicate growth in production capacity. Similarly, while a sustained increase in employment rates can coincide with economic growth, it is not a direct definition of growth itself; rather, it is often a result of growth.
