  1. POPULATION PATTERNS Chapter 6 Section 1

  2. The People • 5% of world’s pop. • Canada (2008): 33 million • US (2008): 303 million 3rd largest • What is the common tie b/w everyone in these countries? • All are immigrants or descendants

  3. Immigration • 1st wave- across land bridge from Asia (Native Americans) • Several waves to follow- all grps. affected by push-pull factors of that time • Timeline site • Were they always accepted/appreciated?

  4. Immigration • 1998- 9% of population • 2002- 11.8% of population • 33.1 million • All time high is 14.8% in 1890

  5. Population density & distribution • Canada is lgr country…but 8 ppl/sq. mile • Most is inhospitable  90% live on border with US/ middle prairies/ W. Coast

  6. 2002

  7. Population density & distribution • US has 77 ppl/sq. mile (NJ is highest) • Widely distributed • NE/ Great Lakes = most dense (history & industry) • Pacific coast  climate, resources, $ • California #1 state in # (but also bigger) • S and SW = fastest growing (climate, jobs, land space) • Retirees, immigrants from LA

  8. 2000

  9. 2006

  10. 1990

  11. 1990

  12. 1990

  13. 1990

  14. Cities • Use of machines  large commercial farms  fewer farmers needed  urbanization • Metropolitan area • Pop. Of 50,000+ • Outlying communities (suburbs) • 81% of US (276 m.a.) and 60% of Canada (25 m.a.)

  15. Metropolis Suburbs AUSTIN Major city DALLAS/FORT WORTH HOUSTON SAN ANTONIO Cities Megalopolis

  16. Urban Sprawl • Define urban sprawl. • Rapid spread of cities & suburbs, often poorly planned due to speed • Define metropolitan area. • A major city & its surrounding suburbs (NYC, Toronto) • Define Urban core. • “walking city”: downtown business district, all bldgs are in walking distance of ea. other

  17. Urban Sprawl • What innovations led to the expansion of the urban core? • Electric street cars, commuter rails (trains/subways) build homes along rail lines (1890s) • How did the invention of the car change the lives of city workers? • Didn’t have to live along rails paved roads allowed ppl to build outside core and commute (20s)

  18. Urban Sprawl • Define urban fringe. • Suburbs forming on outer ring of city • How does movement from city to suburbs impact city life/econ. wellbeing? • Businesses move closer to homes (away from urban core $ decline in inner core • Define rural fringe. • Small towns/farms outside of suburbs, connected by roads  eventually develops

  19. Urban Sprawl • Diagram 8 Katy I 10 610 Urban Core 99 59 Urban Fringe Rich/Rose SL Rural Fringe Suburbs Wharton

  20. Urban Sprawl • 3 arguments SUPPORTING growth • New homes on cheaper rural land (cost ) • New job opportunities building houses, roads, etc. • More $ spent in local stores • Property taxes help schools & roads

  21. Urban Sprawl • 3 arguments AGAINST growth • Destroys habitats/wildlife • Reliance on cars  traffic, pollution • Taxes in rural areas as land develops • Big businesses can move to rural areas & put sm. business out.

  22. Cities • Why do ppl settle on the coast/ rivers? • PORTS, trade, commercial links, natural resources • What are Seattle & San Francisco known for? • Silicon Valley- computer & aerospace industries • Although DFW is a huge leader as well!
