In service provision analysis, what does a catchment area represent?

• A. A drainage basin unrelated to services.
• B. The geographic area served by a facility.
• C. A political boundary only.
• D. A climate zone.

Answer: (B)

In service provision analysis, the catchment area is the geographic area from which a facility draws its users or customers. It represents who can realistically access the service, based on travel distance or time, transportation options, and the presence of competing facilities, and it informs planning for coverage, capacity, and equity. It isn’t a drainage basin, a political boundary, or a climate zone—those terms describe other physical or administrative features, not the area that a service actually serves. Understanding the catchment area helps estimate demand, size up gaps in coverage, and identify underserved populations.
