2
Purchasing Power Parity (PPP). This is a comparative measure of the cost of goods in different countries. It is often applied to a ‘basket of goods’. The basket of goods contains a group of basic goods and services that are needed, and the comparison is often made between the numbers of hours needed to work to make enough income to buy this ‘basket of goods’ in different countries.
3
Gross Domestic Product (GDP). This is the value of all goods and services produced within a country, usually over one year. It is often calculated as the sum of consumption + investment + government spending + exports – imports.
4
Gross Domestic Product per person (GDP per capita). This is a more useful measure to Geographers, and is the GDP of a country divided by the total population. It is often used as a measure of the relative income of people within different countries.
5
Gross National Income per person (GNI per capita). This is now used more frequently and has similar comparative values to GDP per capita and the now infrequently used GNP per capita.
6
Physical Quality of Life Index (PQLI). This is an attempt to measure the comparative quality of life in different countries. It is an index calculated from the literacy rate, infant mortality rate and life expectancy. Each is given an equal weighting and the PQLI is shown on a 100 point scale.

How much money do you think the world’s top 100 billionaires earn, compared to the world’s poorest 100 countries? How many US dollars do you think each earn? per second?

The world’s top 100 billionaires earn $9000 per second. The world’s poorest 100 countries earn $4000 per second. During 2006 the world’s 100 poorest countries total wealth (GDP) grew by 7.3%. The world’s top 100 billionaires’ wealth grew by 24.7%.
