Question

can you say which sector has grown the most over forty years​

Answer 1

Answer:

Tertiary sector.

Explanation:

Though all the three sectors had a growth over thirty years, maximum growth was seen in the tertiary sector. 

This is because in any place services like banking, telecom, telegraph, transportation health care facilities like hospitals are very much required and mandatory.

Secondly, there was a boom in agriculture and industry which requires a trade, transport storage etc that fall under service sector.

Third, as income levels rise, certain sections of people start demanding many more services like eating out, tourism, shopping, private hospitals, private schools, professional training etc. 

Fourth, over the past decade or so, certain new services such as those based on information and communication technology have become important and essential. The production of these services has been rising rapidly.
