This is why statisticians don't like to extrapolate beyond the existing data:
When Elvis Presley died in 1977, there were an estimated 37 Elvis impersonators in the world. By 1993, there were 48,000 Elvis impersonators, an exponential increase.
Extrapolating from this, by 2010 there will be 2.5 billion Elvis impersonators. The population of the world will be 7.5 billion by 2010.
Therefore, every 3rd person will be an Elvis impersonator by 2010.
