Economic growth specifically refers to a sustained increase in the output of goods and services per person (per head) in an economy. This means that over time, the economy is producing more goods and services per person, which can lead to higher standards of living, increased employment opportunities, and improved overall economic well-being. It is not about relying on imported goods in preference to home-made goods, depleting natural resources, or simply increasing the total number of people in the economy. Rather, it is a result of changes in the technical and institutional arrangements of the economy that lead to increased efficiency, productivity, and innovation.
