A good indicator for growth in for example China and India is car ownership, where in the Netherlands on average 1 in every 2 people owns a car, in Chine on average 1 in every 32 people owns a car (year 2011), but this is predicted to change as can be seen in the following picture.ย And keep in mind that in China and India live around 2.4 billion people, if 1 in 2 owns a car there would be 1.2 billion cars instead of the current 40 million.
