CHINESE ZODIACS AND THE WEALTHY

According to a Chinese zodiac report that I read in the newspaper last week, most of the richest people in Malaysia were born in the Year of the Ox.  Nanyang Siang Pau reported that Wealth-X firm said that most of the richest men in Asia were born in the Year of the Rabbit.
In Singapore, most of the wealthiest men were born in the Year of the Rooster, Tiger in Indonesia, Dragon in Thailand, Snake in Taiwan, Horse in Japan, Rat in India and Rabbit for both China and South Korea.

I wonder about the statistics for the world.  Could it be the Rabbit?
