Answer:
We can use the example of the Greater Accra region, one of the new regions of Ghana.
Explanation:
The Greater Accra region consists essentially of the city of Accra, and its immediate sorroundings, and has over 4 million people.
As the most populated region in the country, its regional economy is the most important for Ghana. It is where a great part of the country's industrial and service sectors are located.
