UK economic structure had experienced considerable changes over the last century - the graph

Given is the graph providing information about the contribution of three separate sectors to the economy of the United Kingdom in the twentieth century. It is evident that while the proportions of agriculture and manufacturing declined throughout the period, the percentage of business and finacial services increased steadily.

In 1900, agriculture accounted for nearly half of the UK economy. This number rose marginally to above 50% in 1950, before plummeting to almost zero by 2000. Manufacturing sector also followed a similar pattern. Constituting more than 40% of the economy in 1900, this number commenced to decrease gradually for the rest of the period, dropping to a low of only 15% in 2000.

In contrast, the rate of business and financial services saw an exponential increase. Standing at a mere 4% in 1900, the proportion of these services went up steadily, reaching a peak of more than 30% at the end of the period.

In conclusion, it is apparent from the data supplied that the UK economic structure had experienced considerable changes over the last century, with the increase in the rate of business and financial services and the decline in the proportions of agriculture and manufacturing.

Well , the structure for this task is generally;
1.Introduction
2. Overview
3. Details


... as per that structure, you should have two separate lines as the first one well fits in with the definition of introduction and the second one which describes the main trends can be considered as an overview.

Good Writing!

The graph provides information


This sentence could form an overall paragraph. Also, I don't think the conclusion paragraph is necessary as it just repeats the point you already mentioned.

Overall, you write very well :)

Many thanks for your helpful feedback :D
