The study looked at how different types of businesses grow in Salt Lake County, Utah, as the city expands. They found that service companies like banks and law firms tend to move to new areas, while manufacturing companies tend to spread out into the suburbs. The researchers discovered that service companies are more influenced by the community they are in, like how many people live there and how educated they are, while manufacturing companies are more affected by being close to other businesses. This shows that different types of businesses have different preferences for where they set up shop. The study also showed that urban sprawl, with its low population density and focus on cars, can impact how businesses grow in an area.
