Measuring prosperity in a broad sense is difficult.
How do we measure happiness? How do we measure the appreciation of the environment?
Prosperity in a narrow sense is easy to measure.
We can measure the:
Gross domestic product (GDP)
The gross domestic product is the volume of total production of all companies and government authorities in a country.
The GDP indicates how much is produced in a country and therefore is a
benchmark of prosperity (in a narrow sense).
We say there is economic growth when the GDP increases.
That means that the economy grows when thet country’s total production increases.
