The world is getting bigger,richer,more urban and older.Global population today is 7.3 billion.The UN predicts 9.7 billion by 2050.But pay special attention to the subtrends within the megatrends.Take the growth of the global middle class.Today that population is around 2 billion.By 2050,this number could,more or less,double.When people move from poverty to the middle class,they want and,therefore,buy things.What do they want?Sanitation.Air-conditioning.Morden housing.Higher-protein diets.The ability to travel.Trillions of dollars will be made serving these needs.
Urban population will grow from 4 billion to 6.3 billion by 2050.Trillions of dollars will be made in the housing and transportation industries.
The world's older population (people over 65) will grow from today's 600 million to 1.5 billion or so by 2050.Trillions of dollars will be made in a range of new drugs,medical procedures and health services aimed at meeting the needs of seniors.
