What type of urban service tends to require a large market area to remain profitable?

High order services are characterized by their need for a larger market area to sustain profitability. This is because these services, such as specialized medical practices, luxury goods stores, and high-end restaurants, tend to require a higher number of customers who are willing to spend more money on their goods or services. They often have a broader range of functionalities and attract clients from a wider geographical area, drawing customers not just from the immediate surroundings but from neighboring regions as well.

In contrast, low order services, community services, and local convenience stores typically cater to daily needs and are designed to serve smaller populations. These types of services can thrive in smaller market areas since they provide essential goods and services that residents need on a regular basis. Therefore, while they are important for local economies, they do not require the same extensive market and customer base as high order services do to remain viable.
