Have you ever wondered how much your birth order affects your life? From relationships and your health to even your career and education, where you fall in the family can have substantial effects on your personality and how you interact with others. So whether you and your older sister are the most stylish siblings around or you rock your only child status like a badge of honor, see how your personality lines up with the research.

Oldest Child

If you鈥檙e the oldest child like Kourtney Kardashian, you might be a little more Type A than the rest of your siblings. As the firstborn, your parents were likely more strict with you, shaping your high-achieving personality. A study at the University of Essex found that firstborns have a 16% higher probability of finishing multiple degrees, which usually lead to careers in medicine or law. And when it comes to getting hitched, you鈥檙e more likely to do it sooner, perhaps as a way of being the 鈥渄utiful firstborn.鈥

As far as health goes, you might have more allergies since parents usually shield their first child from EVERYTHING that might be a little bit dirty. But it鈥檚 this exposure to germs that might make children more resistant to allergies later on in life. Oh well, your parents were new at this whole 鈥渞aising children鈥 thing.

Middle Child

If you鈥檙e a middle child like Pippa Middleton, you鈥檙e more sociable than most since you grew up in a full house. You had to learn how to compromise early on, so you鈥檙e great at team sports and activities. Because of this, you excel in careers that involve collaboration and interpersonal skills like sales or marketing. And because of your competitive nature, you did well in school, doing whatever it took to prove you were the best.

Luckily, you鈥檙e more likely to have a lower BMI than your older siblings, but unfortunately, you鈥檙e more prone to chronic fatigue syndrome. And when it comes to relationships, you鈥檙e the best kind of girlfriend. Since you don鈥檛 expect the spotlight or perfection, you鈥檙e laid back and easy to get along with. (Photo via聽Tim P.

Youngest Child

If you鈥檙e the baby of the family like Solange (although, living in Bey鈥檚 shadow might warrant a category all its own), you tend to be the most popular in your social circles. All that extra attention you got growing up shaped you into a social butterfly. But school didn鈥檛 come so easily to you, and you worked the hardest to keep up. Many parents admit to not supervising the youngest鈥檚 homework as much as the other children, which might have contributed to the problem.

Being used to the spotlight, you might seek a more creative career to get all that attention you crave. This might be a result of your addictive personality, which also makes the babies of the family more prone to other, unhealthy addictions. You also seek relationships that are emotionally safe, and you try聽avoid confrontation. Since you grew up with others doing things for you, you tend to expect the same out of a relationship.

Only Child

If you鈥檙e an only child like Chelsea Clinton, you鈥檙e an independent person. This should come as no surprise, since you were rarely interrupted as a child and you never had to try too hard to get attention. Possibly due to receiving the same amount of parental pressure as firstborns, only children tend to be high achievers. And since you鈥檙e so used to being at the top in your parents鈥 minds, you work hard to reach the top in your career as well.

Being an only child can also take a toll on your mental health, since you鈥檙e the go-to person when your parents fall ill or need help. The pressure of caring for your parents as they age can be a stressor that those with siblings don鈥檛 experience in the same way. And when it comes to relationships, only children don鈥檛 have any particular issues, unless their parents are divorced. A divorce can have a strong impact on how an only child views their own relationships. (Photo via聽Dimitrios Kambouris/Getty)

Twins

If you鈥檙e lucky enough to be a twin, like Mary-Kate and Ashley Olsen, you have a unique bond that can be hard for others to understand. But this bond can make it difficult to find independence or your own personality. Education isn鈥檛 high on twins鈥 list of priorities, but they excel in going into business for themselves. Twins tend to be great entrepreneurs since they already have the perfect business partner.

No particular health issues stand out for twins, but relationships can be a little more difficult for the duo. Finding a connection with someone that rivals the one you have with your sibling might sound like quite a task, and the pressure this puts on a potential partner can sink a new relationship pretty quickly. But that doesn鈥檛 mean it鈥檚 impossible.聽(Photo via聽Taylor Hill/Getty)
