Question

why economic devolopment is considered to be a wider concept than economic growth

Answer 1

Economic development shows the standard of living of the people of the country which shows a more clearer picture of the country's progress economically.
But Economic growth shows only the Per Capita Income or the PCY of a country which can always even be false as the wealth may even be concentrated in a few hands and poverty may still prevail while the PCY of the country is quite high due to the high National Income
