Saltlake Utah has many informal neighborhoods. The eastern portion of Saltlake Utah has higher property values than its western counterpart. This is a result of the railroad being built in the western half as well as scenic views from inclined grounds in the eastern portion. Housing in Saltlake Utah is more affordable on the west side, which results in demographic differences. Saltlake's Interstate 15 was also built in a north-south line, further dividing east and west sides of Saltlake Utah.
The west side of Saltlake Utah tours has historically been a working-class neighborhood, but recently the more affordable nature of the area has enticed many professionals to the neighborhood. For example, the small, increasingly trendy Marmalade District on the west side of Capitol Hill, considered seedy as recently as 5 years ago, was heavily gentrified and is now an eclectic and desirable location. During the 1970s and 1980s, gang activity was also centered in the western neighborhoods of Rose Park, Poplar Grove, and Glendale.
