Overall, the graph shows a significant shift in the economic contributions of these sectors. In the early 1900s, agriculture was the leading sector, while business and financial services played a minimal role. However, by the end of the century, business and financial services had grown to dominate the economy, with agriculture’s contribution sharply declining.
In 1900, agriculture accounted for the largest portion of the UK economy, contributing around 50%. This sector’s share remained substantial until around 1950, when it began to decline sharply. By 2000, agriculture’s contribution had fallen to less than 10%, indicating a drastic reduction over the century.
Manufacturing also started the century with a strong presence, contributing approximately 45% in 1900. Unlike agriculture, its decline was more gradual. It remained a dominant sector until 1975, when its share began to decrease steadily. By the end of the century, manufacturing’s contribution had dropped to about 15%, reflecting a steady decrease in importance.
In contrast, business and financial services experienced a dramatic rise. Starting at under 5% in 1900, this sector saw gradual growth through the first half of the century. By 1975, it contributed around 20%, and by 2000, business and financial services had become the largest contributor, accounting for nearly 35% of the economy.
