Question

Suppose:

In 1990, industrialized countries were producing 9 million tons of textiles, whereas developing countries were producing only 1 million tons of textiles.

In 2017, industrialized countries were producing 81 million tons of textiles, whereas developing countries were producing only 19 million tons of textiles.

Question : What has happened to the global share (in percentage of total production) of industrialized countries textile production?

Answer 1

Let us put the information in tabular form -

Year	1990	2017
Industrialized countries	9	81
Developed countries	1	19
Total output ===>	10	100

We convert the above data for each set of countries by dividing by total output in each year so as to calculate their respective shares in percent terms -

Year	1990	2017
Industrialized countries	90	81
Developed countries	10	19

We observe that the share of industrialized countries has declined from 90% to 81% between 1990 and 2017.
