Jobs and Birth Order

Revised January, 2011

All men may be created equal; but a look at their pay stubs will tell you that their incomes are not.

Blame it on social class, education -- even luck, but according to Dalton Conley, New York University professor of sociology and public policy, inequality begins at home. In his book 'The Pecking Order: Which Siblings Succeed and Why,' Conley says that 75 percent of the income inequality between individuals in the United States occurs between siblings in the same families. He points to the diverse fortunes of Bill and Roger Clinton and Jimmy and Billy Carter as examples.

Research shows that first-borns (and onlys) lead the pack in terms of educational attainment, occupational prestige, income and net worth.

Conversely middle children in large families tend to fare the worst. (Marcia! Marcia! Marcia!)

"A child's position in the family impacts his personality, his behavior, his learning and ultimately his earning power," states Michael Grose, author of Why First-Borns Rule The World And Last-Borns Want To Change It, "Most people have an intuitive knowledge that birth order somehow has an impact on development, but they underestimate how far-reaching and just how significant that impact really is."

Conley concedes that birth order is significant in shaping individual success, but only for children of large families -- four or more siblings -- and in families where finances and parental time are constrained. (In wealthy families, like the Bushes and Kennedys, it has less effect.)

Here's a look at what impact your birth order may have on you:


More conscientious, ambitious and aggressive than their younger siblings, first-borns are over-represented at Harvard and Yale as well as disciplines requiring higher education such as medicine, engineering or law. Every astronaut to go into space has been either the oldest child in his or her family or the eldest boy. And throughout history -- even when large families were the norm -- more than half of all Nobel Prize winners and U.S. presidents have been first-born.

Famous eldest children include: Piers Morgan, Lady Gaga, Zac Efron, Taylor Swift, Richard Branson, and Winston Churchill. And macho movie stars are first-born, too, including Clint Eastwood, John Wayne, Sylvester Stallone, Bruce Willis and all the actors who have played James Bond.


Middle children are more easy going and peer-oriented. Since they can get lost in the shuffle of their own families, they learn to build bridges to other sources of support and therefore tend to have excellent people skills. Middle children often take on the role of mediator and peacemaker.

Famous middle children include: Sarah Palin, Bill Gates, Donald Trump, Tim Allen, Anne Hathaway, Joe Jonas, Owen Wilson, and Martin Luther King, Jr.


The youngest child tends to be the most creative and can be very charming -- even manipulative. Because they often identify with the underdog, they tend to champion egalitarian causes. (Youngest siblings were the earliest backers of the Protestant Reformation and the Enlightenment.)

Successful in journalism, advertising, sales and the arts.

Famous youngest children include: Michelle Obama, Jon Stewart, Johnny Depp, Jake Gyllenhaal, Paula Abdul, Prince Harry, Matthew McConaughey, and Janet Jackson.

Only Children

Only children have similar characteristics to first-borns and are frequently burdened with high parental expectations. Research shows they are more confident, articulate and likely to use their imagination than other children. They also expect a lot from others, hate criticism, can be inflexible and are likely to be perfectionists.

Famous only children include: Robin Williams, Natalie Portman, Tiger Woods, Lance Armstrong, Daniel Radcliffe, Joy Behar, Selena Gomez, Rudy Giuliani, Frank Sinatra, and Leonardo Da Vinci.


Because they hold equal status and are treated so similarly, twins turn out similarly in most cases.

Famous twins include: Advice columnists Ann Landers and Abigail Van Buren, Jenna and Barbara Bush, Mary Kate and Ashley Olsen, Gisele Bundchen (twin Patricia Buchden), Scarlett Johansson (twin Hunter Johansson), Vin Diesel (twin Paul Diesel), Ronde and Tiki Barber

Dr. Frank Sulloway, a behavioral scientist and visiting professor at the Institute of Personality and Social Research at University of California, Berkeley and author of the book, 'Born To Rebel: Birth Order, Family Dynamics and Creative Lives,' says first-borns are more similar in personality to first-borns in other families than they are to their own younger siblings. He adds that youngest children are often more similar to the youngest child in another family than his or her own elder siblings. He says this is because the family is not as much a "shared environment" as a set of niches that provide siblings with different outlooks.

Conley agrees, but stresses that these are just general trends -- and that the whole birth-order theory can be turned on its head depending on the child's personality, the age gap between siblings and the family circumstances each child experiences during his or her formative years.

The results come from studies and are generally true. They didn't say 100% true. So why all the arguing? They forget to report a few important after four years break between siblings, the next child will fare like a first born. Meaning, a boy born first who is followed four years later by another boy will likely have a simular personality and have simular success. Also, a first born boy and a first born girl will likely both have like personalities and both be successful.

Personally I don't think this is complete crap. i think it depends on your situation. I am the oldest child in my family and have a younger sister (by 3 years) and a younger brother (by 5 years). We actually all fall into those catergories. except my sister the middle child who is not really a people person. but i am the most successful so far (i just graduated last year with a 3.8 gpa while my siblings barely keep b's in school) and I was way more mature at my siblings ages than they are now. i basically raised my siblings. My sister is veyr different from me and my brother and lashes out when she thinks we team up on her. her grades are normally average while my brother is mor eof the less school more music type of guy and plays the guitar and draws alot. so i found it strange that we fit into the catergories while the older family (in the late 40's or 50's) did not.

I am 42 years old. I am youngest of 2. My brother is 45 years old. I have been unemployed for over months. I need to get a new job since Linens 'N' Things went out of business last year. I will go to an occupational center in the city of Los Angeles. I am thinking of doing volunteer work too. My brother has a 20 year old and an 18 year old step daughter. Which are my niece and my step niece.

I agree. I am the oldest of 5. I am a college graduate. I am not bragging, it is truly a blessing that I make the most. This article applies. The middle child is also a college degree. Does not do anything with it. She is not a failure by any standard. Her degree just sits. Youngest lives at home with mama.

I have read a birth-order book previously (not restricted to pay scales but to personalities) and understand what this is TRYING to say. I am a first-born, but being female in an old-fashioned rural community, my father believed I was worthless and told me so, prizing his next three sons over me every step of the way, teaching them the same abusive behaviors. Now I have a bachelor's degree (my GPA higher than any of my brothers'), am divorced (picked a real abusive "winner" there) raising four kids, holding eight part-time jobs and drive a car that is falling apart around me that doesn't qualify for the "cash for clunkers" program because a computer decided it doesn't. I have more creativity, empathy, loyalty, ingenuity, faith, understanding, heart and presence in my children's lives than the guys in my family, but being first-born didn't work for me in the paycheck world either. These aren't exacting standards. Just generalities to possibilities. Let's do a Clinton: Depends what "successful" is...
