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.

© T. M. Whitmore

Effects of colonialism•Removal and replacement of

local power structures, institutions, economies and populations.

•Enduring connections to colonial powers – early globalization

•Global “underdevelopment”?

Globalization

•A process of global integration

•Underlying causes are primarily economic and technological

•Economic, demographic, social, cultural, political and environmental manifestations

© T. M. Whitmore

Primary “Sector” of economies

•Agriculture and raw material production (mining)

•Relatively slow growing economically

•World’s resources are very unevenly distributed

© 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

© T. M. Whitmore

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

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

•MortalityDeath rate: deaths per 1000 pop/yr

Eo (life expectancy at birth)

Demography Concepts II

•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

•“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

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

Population Movements•Migration

• 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

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.
