Who Created the Hoyt Sector Model? | Urban Geography Facts

The Hoyt sector model was created by economist Homer Hoyt in 1939 as an alternative to the concentric zone model of urban development. Hoyt proposed that cities grow in wedge-shaped sectors rather than uniform rings, with land use and property values extending outward from the central business district along transportation corridors. His model reflected patterns he observed in U.S. cities, especially Chicago, where high-rent residential areas developed along major rail lines and roads, while industrial and lower-income zones occupied adjacent or less accessible sectors.

Hoyt based his theory on extensive analysis of land values across more than 100 American cities. In his 1939 study One Hundred Years of Land Values in Chicago, he mapped how property values changed over time and found that affluent neighborhoods did not form complete rings around the city center. Instead, they spread in narrow wedges, often following transit routes. For example, in Chicago, high-value housing expanded northwest and south along elevated rail lines, while industrial activity concentrated near freight lines and rivers, creating distinct sectors of development.

This sector pattern arises because transportation infrastructure shapes accessibility and desirability. As cities grow, development intensifies along these corridors, reinforcing existing trends. A wealthy sector tends to remain high-rent as it expands, while working-class or industrial zones face fewer incentives for redevelopment. The model improved upon Ernest Burgess’s earlier concentric zone model by accounting for directional growth and economic gradients influenced by transport networks.

While later models like the multiple nuclei model introduced more complexity, Hoyt’s sector model remains relevant for understanding mid-20th-century urban form in North America. It helps explain why certain neighborhoods maintain socioeconomic status over time and how infrastructure decisions shape long-term land use. However, it applies best to cities with a single core and radial transport systems. It is less effective in polycentric, planned, or highly regulated urban environments where growth does not follow linear corridors.

An example of the sector model in action can be seen in Dallas, where affluent suburbs such as those along US-75 developed in a northeastward wedge, following highway access to downtown. This corridor became a high-income sector, while industrial activity and lower-cost housing remained concentrated in other wedges, particularly to the south and west.

Key Takeaways

• The Hoyt sector model was developed by Homer Hoyt in 1939 to explain urban growth in wedge-shaped sectors radiating from the central business district.
• It emphasizes the role of transportation routes and land value patterns, showing how high-rent areas extend outward along corridors.
• Based on analysis of Chicago and other U.S. cities, the model improved on the concentric zone model by reflecting real-world development trends.
• Though less applicable to modern polycentric cities, it remains a foundational concept in urban geography Encyclopaedia Britannica.
