© T. M. Whitmore LAST TIME- Questions? Agriculture and rural development continued V: Internal Colonization of Tropical Lowlands - Amazonia The issue of lowland tropical deforestation Mexican Agriculture- an example of a dual system Other examples of Commercial Agriculture in LA

© T. M. Whitmore Population (2007 estimates) Latin America & Caribbean ~ 569 m USA ~ 302 m World ~ 6,525 m Caribbean ~ 40 m Central America (with Mexico) ~ 148 m Mexico ~ 106.5 m South America (with Brazil ~ 381 m) Brazil ~ 189 m Mexico + Brazil ~ 295.5 m (> ½ of LA; ~ USA)
4
© T. M. Whitmore Demography: Growth related Rate of Natural Increase (RNI) Meaning of “crude” in demography Crude Birth Rate (CBR): live births/1000 pop in a given year Crude Death Rate (CDR): deaths/1000 pop in a given year CBR - CDR = RNI (assumes no migration) in a given year
5
© T. M. Whitmore Rate of Natural Increase (RNI)/yr Latin America ~ 1.5%/yr USA ~ 0.6%/yr World ~ 1.2%/yr More Developed World ~ 0.1%/yr Lesser developed world ~ 1.5% - 1.8%/yr Caribbean ~ 1.1%/yr Central America (including Mexico) ~ 1.8% Mexico ~ 1.7 %/yr South America (including Brazil) ~ 1.5%/yr Brazil ~ 1.4%/yr Notable extremes Historical trends: 1950s - 1980s Declining but less rapidly now
6
© T. M. Whitmore Total Fertility Rate (TFR) = average total number of births to a woman in her lifetime (superior to CBR) ~ 2.1 => parents only replacing themselves (called replacement level fertility) need the extra 0.1 due to childhood deaths
7
© T. M. Whitmore Fertility (TFR) Latin America ~ 2.5 USA ~ 2.1 World ~ 2.7 More Developed World ~ 1.6 Lesser developed world ~ 2.9 - 3.3 Caribbean ~ 2.5 Central America (including Mexico) ~ 2.7 Mexico ~ 2.4 South America (including Brazil) ~ 2.4 Brazil ~ 2.3 Notable extremes
8
© T. M. Whitmore Death related (mortality) Mortality measured by “life expectancy at birth” (E o) = AVERAGE projected span of life at the date for a poplife expectancy at birthE o Infant Mortality Rate (IMR)IMR # deaths of infants (< 1yr)/1000 live births in a given yr
9
© T. M. Whitmore Life expectancy at birth (E o) Latin America ~ 73 yrs USA ~ 78 World ~ 68 More Developed World ~ 77 Lesser developed world ~ 64 – 66 Caribbean ~ 71 Central America (including Mexico) ~ 74 Mexico ~ 75 South America (including Brazil) ~ 72 Brazil ~ 72 Individual extremes
10
© T. M. Whitmore Infant Mortality Rate (IMR) Closely correlated with E o & very diagnostic of social underdevelopment and poverty Latin America ~ 24 (per 1000 live births -or 2.9%) USA ~ 6.5 World ~ 52 More Developed World ~ 6.0 Lesser developed world ~ 57 – 61 Caribbean ~ 38 Central America (including Mexico) ~ 23 Mexico ~ 21 South America (including Brazil) ~ 24 Brazil ~ 27 Individual extremes
11
© T. M. Whitmore Population age structure - youth Youthful pops: % of pop < 15 years old USA 20% World 28% Lesser developed World 31% - 34% More Developed World ~ 17% Latin America 30% Central America with Mexico 33% Caribbean 28% South America 29% Latin American extremes & consequences
12
© T. M. Whitmore Population age structure - aged Aged pops: (> 65) USA 12% World 7% Lesser developed World 5-6% Latin America 6% Central America with Mexico 5% Caribbean 8% South America 6% Latin American extremes & consequences
13
© T. M. Whitmore Population age structures Population pyramidpyramid Concept of dependency ratio (pop aged 0-15 + pop aged 65+) *100/ Pop age 15-65 USA dependency ratio 100*(20% +12%)/68% = 47 Developing world dependency ratio 100*(34% + 5%)/61% = 64 Latin America dependency ratio 100*(30% + 6%)/64% = 56

Geographic distribution of population High density zones High Low density zones Low South America’s “empty heart” Arid zones in N Mexico & Southern Cone
17
© T. M. Whitmore Urbanization Proportion of a country’s pop living in cities World = 49% Global South = 42-43% Global North = 75% USA = 79% LA = 76% LA Extremes in LA Large city urbanization in LA (% in cities > 1 million)
18
© T. M. Whitmore Urbanization II Mega-cities Emerging Megalopolis zones Central Mexico Central Mexico South Brazil triangle & Río de la Plata South Brazil triangle Concept of primacy Single city in a country that dominates in pop, culture, economic development, etc. Examples: Examples Santo Domingo Guatemala City Mexico City Lima

LA cities in World’s top 100 (19 of the top 100)
29
© T. M. Whitmore Roots of urban growth Demographic R—to—Urban migration Natural increase Economic Industrialization Rural stagnation Organizations Banks and governments
30
© T. M. Whitmore Benefits from urban growth Efficient provision of social services Cities are centers of information flow and knowledge Concentrated (and better educated?) labor pool Physical infrastructure often better Cities concentrate “human capital” Cities are a huge internal markets Easier linkages between industries Cities are often “better off”
31
