Frequently Asked Questions
Is 'sector' only used for business and economy?
No. While it's very common in economic discussions (e.g., 'sector privado'), it is also used for physical areas or zones, like 'el sector norte de la ciudad' (the northern area of the city).
How is 'sector' different from 'área'?
They are often interchangeable when talking about a physical zone. However, 'sector' often implies a formal, defined division or segment that has been intentionally marked or separated (like a military zone or a business division), whereas 'área' is more general.
