In central-place theory, threshold refers to the minimum number of consumers required to support a service. This concept belongs to which theory?

• A. Central-place theory
• B. Sector model
• C. Concentric Zone Model
• D. Multicentered Model

Answer: (A)

The concept being tested is the idea of threshold as a fundamental part of Central-place theory. This theory explains how settlements organize to provide goods and services to surrounding populations, forming market areas or hinterlands. Threshold is the minimum number of consumers needed for a service to be viable; if there aren’t enough people nearby to support a shop, clinic, or other service, that service won’t be established in that location. This helps determine why settlements of different sizes exist and how they’re spaced: larger towns offer higher-order services that require larger thresholds and therefore serve broader areas, while smaller towns provide basic services with lower thresholds and smaller market areas. Other models describe urban structure in different ways (growth along corridors, rings around the center, or multiple centers) and don’t center on the viability of services through a threshold in the same explicit way.
