Development: HDI (Human Development Indicator) is calculated by: the per capita revenue ($/year), life expectancy per capita, literacy rates of adults.

Development: HDI (Human Development Indicator) is

calculated by: • the per capita revenue ($/year), • life expectancy per capita, • literacy rates of adults and • educational rates of children under 15

The value is expressed from 0 to 1

2. On a Regional Scale:•In the North: contrast between Northern and Western Europe vs. Southern and Eastern Europe•In the South: even greater contrast between regional areas

- Eastern Africa and Central America, poorest areas- Great heterogeneity between

• emerging powers (BRICS), • intermediary developing countries (baby

tigers like Indonesia)• LEDCs (Less Economically Developed

Countries)

Map 4: Regional HDI African Continent

How can you explain these regional differences in Africa?

Map 5: Discrepancies in HDI Ranking in Europe

Describe the regional discrepancies in Europe

3. On a Country/City Scale:• Case of the NorthUnited States – Wealth Distribution video TED

Map 6: Number of High Income Households for Each County in the US 2007-2011

Where is wealth concentrated geographically in the U.S.?

Map 6: Annual per Capital Income by Province in China (blue above the mean (= average), orange below the mean

How would you characterize the distribution of wealth in China?

Case of the South:

Contrast between development in China on the coast and inland, concentration of wealth in urban areas (Beijing and Shanghai) BUT map does not show the concentration of poorest population in slums or insolubrious conditions in cities

II. Changing needs for 9 B people in 2050

A. World population growth increases development disparities

1. Demographic growth at different pacesDemographic transition – spread throughout southern countries from

1900 to 1950 – ceased in the first half of the 20th century in

industrialized countries

Q1:Describe the distribution of areas of high and low population densities.

Q2: Suggest reasons for the patterns you have described.

Consequences:– Today part of subsaharan Africa and the Middle

East are still in the stage of demographic explosion– In India and China, demographic transition is

coming to an end but it has caused an effect of inertia. Even if fertility rates have decreased, the generation at an age to procreate remains numerous

Which countries have the highest rate? The lowest rate? Why?

2. Increased Needs:• Vital necessities (food, water, energy and

medical care)• Lack of resources for the largest number

3. Bigger Gaps:• Between northern and southern

countries• Between southern countries who have

completed their demographic transition and those who are still undergoing demographic transition

population pyramid• graphical illustration that shows the distribution

of various age groups in a population which forms the shape of a pyramid when the population is growing. It is also used to determine the overall age distribution of a population;

• population plotted on the X-axis and age on the Y-axis, one showing the number of males and one showing females in a particular population in five-year age groups

Population Pyramids and Demographic Transition

Stage 1: balance between birth rate and death rate, very slow increase of the population

Stage 2: decline in the death rate while the birth rate remains high. Causes: improvement in food supplies and public health

Stage 3: decline in the birth rate, Causes: birth control, children become an added expense for the family

Stage 4: birth rate and death rate at the same level: stability of the population.

At which stage of the demographic transition are these countries?

• Between towns and countryside: in 2010, more than 50% urban dwellers on earth (should go to 70% in 2050); population will be concentrated in cities

Urbanization

• If urbanization is stabilized in the North, it is exploding in the south• Causes? Massive rural flight and natural growth rates

in cities• Giant agglomerations are multiplying in emerging

countries. In Asia, the urban population is rising at the rate of 1 million inhabitants per week.
