Youngest Kids More Likely To Be A Self-Made Millionaires, Says Study. Researchers have found a correlation between risk-taking and being the last-born sibling.
Your success in life may be influenced by your birth order, according to the economist Sandra E. Black. Black points to research she and her colleagues have conducted that found that firstborns tend to be smarter, richer, and all-around more successful than their younger siblings.
The research found that the youngest sibling in a family is way more likely to take risks in their developing careers, and thus end up far more successful and way more likely to be a millionaire. Researchers say this because the youngest kid has a natural tendency to rebel.
Firstborn children are taller compared to those born subsequently, and this height advantage increases sharply over the higher order of birth of siblings.
The firstborn effect
Firstborns tend to possess psychological characteristics related to leadership, including responsibility, creativity, obedience and dominance. They are also more likely to have higher academic abilities and levels of intelligence than their younger siblings.
Eldest daughter syndrome is the burden felt by oldest daughters because of their unique childhood experience. Extra duties are often given to the oldest girl in a family, leading to a shared 'syndrome' of being responsible but overburdened.
A University of Edinburgh study shows first-born children have higher IQs and better thinking skills than their siblings. The study says that shows first-born kids get more mental stimulation than their brothers and sisters.
The study found that first-born siblings are more likely to survive to 100 years when compared to later-born siblings (odds ratio [OR] = 1.77, 95% confidence interval [CI] = 1.18–2.66, p = 0.006).
Scientists in the US made the discovery after reconstructing the family histories of 198 centenarians born between 1875 and 1899. They found that first-born children were 1.7 times more likely than their siblings to live to 100.
Conclusions: First-borns were taller than later-born children, with an incremental height reduction from first to third birth order. These differences were present after correction for genetic height, and associated to some extent with alterations in plasma IGF-I.
Middle children are often the most successful sibling in their families, according to research.
An article in the National Bureau of Economics Research Reporter argues that firstborn children are likely to become smarter, more successful, and richer than their siblings. One possible reason, it says, is that parents are in some ways less invested in parenting after the first go-round.
The best students tend to be the oldest of three children, with a brother less than two years younger than them and a sister at least five years younger. Birth order studies are a dime a dozen, but scientists have spilled far less ink on sibling configurations.
In fact, over two-thirds of millionaires are self-made, according to a 2019 study by Wealth-X and a study by Fidelity Investments.
Millionaire Statistics by Age
The average millionaire is 57 years old. As of 2013, 42% of millionaires are baby boomers (between 57 and 75 years of age), the majority of any age group.
Oldest sibling is smartest, second-born siblings are troublemakers, studies show. The study looked at U.S. Bureau of Labor statistics for 5,000 children from pre-birth to 14-years-old.
The least common birthdays in the U.S. interestingly all hover around major holidays. December 25 (Christmas Day) is the least common birthday, while January 1 (New Year's Day) is the second least common.
First, which month has the least birthdays? The data comes from the Centers for Disease Control and Prevention and the Social Security Administration. The rarest month to be born in is February, making Aquarius the rarest zodiac sign. February is the shortest month of the year, even with a leap year.
Women whose mothers live up to the age of 90 are more likely to have increased lifespan, without suffering from any serious illnesses like cancer, diabetes, or heart disease, a study has found.
Gaps of over five years are associated with pregnancy and birth problems (not just because you're likely to be an older mum) (Conde-Agudelo et al, 2006). With bigger gaps, your children may be into different things so not as close until they're much older.
In addition, because parents give firstborns a lot of responsibility at home—whether it's helping with chores or watching over younger siblings—they can be quick to take charge (and can be bossy when they do). That burden can lead to excess stress for a child who already feels pressure to be perfect.
However the researchers looked at it, first-borns had, on average, an IQ of 1.5 points higher than second-born siblings, who in turn had a 1.5 higher IQ than third-borns and so on.
According to studies, genetics can drive anywhere between 30-75% of the variations in people's IQ levels. However, certain environmental factors and socioeconomic status can prevent a person from achieving their true genetic potential of IQ levels.
Also, is intelligence more of a genetic or environmental trait?” If a person with a high IQ marries someone with a lower IQ, their kids could have most any IQ. The same is true for two high IQ parents (although their kids will tend to have higher IQs).
