What percentage of the world’s population are firstborns?

A friend who espouses a “firstborn psychology” claims that 75% of the world’s population are firstborns and their negative personality traits have a major detrimental impact on society. I can find nothing to corroborate this. Are there such statistics on birth order? (As a firstborn who doesn’t fit the profile, I’m considered an anomaly, he says.) I’d appreciate anyone’s input on the subject before I attempt to refute his theory.
