7. European Settlement Expansion 1st Stage (1600–1750) 2nd Stage (1750–1850) 3rd Stage (1850–1910) Population: Historic Patterns Figure 3.13

8. Westward Migration African-American Migration from the South Rural-to-Urban Migration Migration to the Sunbelt South Nonmetropolitan Growth North Americans on the Move Figure 3.14

9. Amenity Migration • What is amenity migration and what are the push and pull factors?

10. Amenity Migration: Process of people moving to areas due to actual or perceived higher environmental quality • Push Factors: Urban environments (traffic, density, stress, pollution, limited recreation, etc.) • Pull Factors: Recreational opportunities (skiing, biking, kayaking), open space, rural lifestyle, public land, etc.

16. American City Growth Changing Transportation Technologies Urban Decentralization Figure 3.16

17. Historical Evolution of the City • Stage I – Walking-Horsecar Era • Pedestrian city characterized by compactness • Stage II – Electric Streetcar Era • Streetcar suburbs developed as the 30-minute travel radius expanded greatly • Helped to differentiate space in older core city

18. Figure 3.16

19. Stage III – Recreational Automobile Era • Automobiles and highways significantly improved the accessibility of the outer metropolitan ring • Mass wave of suburbanization resulted • Residential space became even more partitioned by class and race • Stage IV – Freeway Era • High speed expressways further extended the 30-minute travel radius

20. Suburbanization • A significant product of this Freeway Era has been suburbanization and the associated suburban sprawl that characterizes many landscapes across the country.

21. Gentrification • Displacement of lower income residents of central-city neighborhoods with higher income residents • Rehabilitation of deteriorated inner-city landscapes • Construction of new shopping complexes and/or entertainment complexes

22. Gentrification New Urbanism Settlement Geographies: Urban Pittsburgh’s SouthSide Works neighborhood is evidence of an urban renaissance on the site of an old steel plant Figure 3.18
