Final answer:
The word 'sector' is used in both economics and urban geography to describe parts of an economy or city that have been conceptually 'cut out' for analysis. Economic sectors are divisions based on types of activities, while the Sector Model in geography divides cities into wedge-shaped urban land use zones.
Step-by-step explanation:
The word 'sector' originates from the Latin secare, meaning 'to cut,' which informs our understanding of the term within the context of economics and geography. In these fields, 'sector' is used to describe distinct parts of an economy or city. These segments are 'cut out' conceptually rather than physically to help analyze the structure of societies and urban layouts.
Understanding Economic Sectors
In economic terms, a sector refers to a part of a society's economy focused on a type of activity. We have the primary sector for raw material extraction, the secondary sector for manufacturing finished goods, the tertiary sector for services like healthcare, and the quaternary sector for ideas and information management. This division into sectors helps scholars understand how societies develop over time, moving from economies that rely primarily on the primary sector to those dominated by services and information in the tertiary and quaternary sectors.
Sector Model in Urban Geography
In urban geography, the Sector Model proposed by Homer Hoyt uses the concept of sectors to illustrate wedge-shaped urban land use zones cutting across the city. These sectors, influenced by factors like transportation routes, reflect the distribution of different types of land use within a city. Here the term sector also implies a 'cut' or division within urban areas into zones with specific economic functions or characteristics, such as residential or industrial zones.
