'Star future' for first-born child
The order in which siblings are born could play a significant role in determining whether they become the next Mick Jagger, Brad Pitt or Tony Blair, a survey has found.
The research released reveals firstborns are more than 3.5 times more likely than siblings to become rock stars - while youngest children are more than twice as likely to become successful actors than their siblings.
Middle children could be pre-destined for a life in politics - with many party leaders being middle children, according to the findings.
The research team studied 100 personalities encompassing the last 20 British Prime Ministers, British Pop Stars, Sports Personalities, BAFTA-winning actors and British self-made multi millionaires to discover links between birth order and occupation.
Three quarters of the study sample of rock stars were oldest or only children, with common traits such as being ambitious, energetic, people pleasers who crave approval.
Such stars following this trend include Mick Jagger, John Lennon, Paul McCartney and only children Van Morrison, Elton John and Eric Clapton.
Middle children are more likely to become the Prime Minister, with 67% more chance than their siblings.
Traits commonly associated with middle children included diplomacy, a competitive nature and a tendency to be peacemakers. David Cameron, Nick Clegg and former premier Gordon Brown are all middle children along with Tony Blair, Anthony Eden, Neville Chamberlain and David Lloyd George.
Statistician, Dr Geoff Ellis, who conducted the research to mark the launch of UKTV Gold's Outnumbered series one, said: "When rock stars are considered in isolation against the rest of the sample group, the probability of the results being purely random are reduced to less than one in a thousand."
The programme premieres on UKTV Gold on Wednesday at 7.30pm.
