Generally 5-7 driving forces are identified to understand the "pressures
of change". Each driving force is made up of a cluster of individual trends.
For example, population is a driving force, but it includes components such as
actual growth rate for each country or geographic area as well as the world, distribution
of poverty and wealth, and indicators that relate to "per capita" analysis.
