Development = bettering of society or of a people (many definitions)•Sustainable development
•Measures of development Economic measures Non‑economic measures - $$ isn’t the best measure necessarily
•Not linear or inevitable.•Connections to colonialism and
globalization.

Development and colonialism
•Global integration has a long and ugly history.
•Particularly important was the control and settlement of overseas territories by European states over the past 500 years.
![Page 4: © T. M. Whitmore Today Economic Development: Diversity Amid Globalization “Sectors” of an Economy Basic human Demography.](https://reader033.fdocuments.in/reader033/viewer/2022051517/56649e725503460f94b7160d/html5/thumbnails/4.jpg)

Effects of colonialism•Removal and replacement of
local power structures, institutions, economies and populations.
•Enduring connections to colonial powers – early globalization
•Global “underdevelopment”?
![Page 5: © T. M. Whitmore Today Economic Development: Diversity Amid Globalization “Sectors” of an Economy Basic human Demography.](https://reader033.fdocuments.in/reader033/viewer/2022051517/56649e725503460f94b7160d/html5/thumbnails/5.jpg)
Globalization
•A process of global integration
•Underlying causes are primarily economic and technological
•Economic, demographic, social, cultural, political and environmental manifestations
![Page 6: © T. M. Whitmore Today Economic Development: Diversity Amid Globalization “Sectors” of an Economy Basic human Demography.](https://reader033.fdocuments.in/reader033/viewer/2022051517/56649e725503460f94b7160d/html5/thumbnails/6.jpg)

Primary “Sector” of economies
•Agriculture and raw material production (mining)
•Relatively slow growing economically
•World’s resources are very unevenly distributed
![Page 7: © T. M. Whitmore Today Economic Development: Diversity Amid Globalization “Sectors” of an Economy Basic human Demography.](https://reader033.fdocuments.in/reader033/viewer/2022051517/56649e725503460f94b7160d/html5/thumbnails/7.jpg)
© T. M. Whitmore
Secondary Sector of economies
•Transformation of raw materials into manufactured goods;
•Formerly dominated the economy of richest nations, but no longer
•Greater growth potential than primary
![Page 8: © T. M. Whitmore Today Economic Development: Diversity Amid Globalization “Sectors” of an Economy Basic human Demography.](https://reader033.fdocuments.in/reader033/viewer/2022051517/56649e725503460f94b7160d/html5/thumbnails/8.jpg)

Tertiary Sector of economies•Provision of services (burger
flippers to college profs)•Now largest sector in richest
nations•Good growth potential•Quaternary Sector: A part of the
tertiary sector involved in information processing; Very rapidly growing in richest nations
![Page 9: © T. M. Whitmore Today Economic Development: Diversity Amid Globalization “Sectors” of an Economy Basic human Demography.](https://reader033.fdocuments.in/reader033/viewer/2022051517/56649e725503460f94b7160d/html5/thumbnails/9.jpg)
Demography Concepts I
•Population growth (usually %/yr) Population growth = births – deaths (rate of natural increase)
+/- migration
•Exponential growth P2 = P1 * e(rt)
the “magic of compounding” e = natural logr = rate of growth/ yrt = number of yrs
![Page 10: © T. M. Whitmore Today Economic Development: Diversity Amid Globalization “Sectors” of an Economy Basic human Demography.](https://reader033.fdocuments.in/reader033/viewer/2022051517/56649e725503460f94b7160d/html5/thumbnails/10.jpg)
•MortalityDeath rate: deaths per 1000 pop/yr
Eo (life expectancy at birth)
Demography Concepts II
![Page 11: © T. M. Whitmore Today Economic Development: Diversity Amid Globalization “Sectors” of an Economy Basic human Demography.](https://reader033.fdocuments.in/reader033/viewer/2022051517/56649e725503460f94b7160d/html5/thumbnails/11.jpg)
•Fertility (birth rate) – 2 measures1: Births per thousand pop/yr 2: Total Fertility Rate (TFR) (total children born/mother in her lifetime)TFR = 2.1 => “replacement level fertility” no growth –parents just replace themselves
Demography Concepts III
![Page 12: © T. M. Whitmore Today Economic Development: Diversity Amid Globalization “Sectors” of an Economy Basic human Demography.](https://reader033.fdocuments.in/reader033/viewer/2022051517/56649e725503460f94b7160d/html5/thumbnails/12.jpg)
•“Recent” population history
•Birth (fertility) and death (mortality) rates world wide
•Annual increment in world population
•Growth in Developed vs Developing (rich vs poor or Global North vs Global South) countries
•Current state of global populations
Current World Demography

Demographic Transition Model
•Idea from W European history•Stages of change in mortality and
fertility => growth over time•Urbanization and industrialization•Different parts of the world are seen
to be in different stages or phases•Different population age structures
Rapidly growing = youngSlow growing = old
![Page 14: © T. M. Whitmore Today Economic Development: Diversity Amid Globalization “Sectors” of an Economy Basic human Demography.](https://reader033.fdocuments.in/reader033/viewer/2022051517/56649e725503460f94b7160d/html5/thumbnails/14.jpg)
Population Movements•Migration
VoluntaryForced (e.g., Refugees)Push vs. Pull Factors
• International migrationRemittances
•Rural to Urban migration

Urbanization
•Global N vs S differences
•Urbanization increasing everywhere:Especially in the in global S
•Megacities increasing in size and number

Plate Tectonics•1912 Alfred Wegner’s
“continental drift”•Plate tectonics (1960s-70s):
moving “plates” hold all the oceans and continents

Plate Tectonics II•Moving “plates”
Sea floor spreading (divergent plates)
Subduction (convergent plates) Pangaea
•Terrestrial hazards: Earthquakes and volcanoes“ring of fire”

World Population Growth Through World Population Growth Through HistoryHistory
Of all people who have ever lived, ~10% are alive now.

The total fertility rate is the mean number of children born per woman, and must be 2.1 for the population to replace itself. Four out of nine people live in countries which have dipped below this.
