Final answer:
The sector of the economy concerned with manufacturing goods is the secondary sector, which is essential for economic growth and contributes significantly to GDP and employment.
Step-by-step explanation:
The sector of the economy concerned with manufacturing goods is called the secondary sector. This sector takes raw materials from the primary sector, such as iron ore or crude oil, and transforms them into finished products like machinery, textiles, and automobiles. The manufacturing industry plays a critical role in an economy, contributing significantly to the gross domestic product (GDP) and providing employment opportunities. Although it has declined in some countries, such as the United States, due to factors like international competition, it remains a pivotal part of economic growth and development.
