The Industrial Revolution and Economic Sectors
The Industrial Revolution began in Great Britain during the 18th century, transforming how the world works through major technological advancements. This revolution sparked widespread industrialization and created the economic sectors we recognize today.
These economic sectors form a hierarchy of economic activities. The primary sector involves extracting raw materials from the earth (mining, fishing, agriculture) and typically makes the least money. The secondary sector processes these materials into finished products through manufacturing. The tertiary sector provides services like marketing, shipping, and restaurants.
Two specialized service sectors sit at the top of the hierarchy. The quaternary sector is knowledge-based, including education and software development. The quinary sector involves high-level decision-makers like government officials and CEOs who make the most money and whose decisions affect billions.
Quick Fact: As countries develop, their economies typically shift from primary sector dominance to greater activity in secondary and tertiary sectors. More Developed Countries (MDCs) have less primary sector activity, while Less Developed Countries (LDCs) rely heavily on primary economic activities.
