Are second-born kids more likely to take after older siblings or choose different jobs, activities and interests?

First-born kids are more likely to be leaders in social situations, but that doesn't mean their younger siblings are going to follow them. Second-born siblings are likely to choose to do the exact opposite of an older sibling.

Are the following celebs oldest siblings, middles, or youngest-born? Billy Crystal, Goldie Hawn, Drew Carey, Jim Carrey and Steve Martin.

Comedians are very likely to be the baby in the family, as all these celebrities are. Youngest kids tend to be funnier, a 2015 survey found. They love attention and are social and outgoing, making them natural performers.

Parents often subconsciously identify with which of their children the most?

Parents tend to understand the child in the family with the same birth-order spot as they have. So a dad who is a youngest child might see his own last-born kid as fun and adorable, while the only-child mom might see the same kid as difficult and irresponsible.

Of the first 23 American astronauts who have been to space, 21 of them were in what birth-order spot?

Those 21 astronauts were the eldest in their families, and the other two were only children. The high levels of academic achievement and discipline required to get to that level of spaceflight are most common among first-born children.

Only children are lonelier, have lower self-esteem and fewer friends than kids with siblings.

Only children have higher self-esteem and as many friends as kids with siblings. Though kids without siblings might spend more time alone, they have stronger relationships with themselves — one of the best bulwarks against loneliness, according to the New York Times.

Should you look for — or avoid — a partner whose birth order is the same as yours?

The best relationships are between mixed birth-order couples — a middle child from one family with an oldest, for instance, or an only child with a youngest. Two middle-born children in a relationship can both be so busy trying to maintain peace that they don't work through conflicts, which stay below the surface. And two youngest-born siblings coupling up increases their chances for going into debt.

Which child is most likely to be super-creative?

According to Kevin Leman, Ph.D., author of "The Birth Order Book: Why You Are the Way You Are," only children's tendency toward creativity stems from being early "self-entertainers" and is also attritbuted to the additional space, resources and attention they get — and the confidence those things inspire.

Which kids are likely to have the highest score on an intelligence test?

According to a 2007 study, eldest-born kids tend to score highest on all kinds of tests and do best academically — though only children, as a rule, do even better. But the number of siblings above you matters too. The more older siblings you have, the lower the IQ tends to be. (Of course there are always exceptions.)

According to a survey, which kid is likely to grow up and earn more than $100,000 a year?

Careerbuilder.com surveyed working adults and found that those who were the eldest in their families were most likely to make more than $100,000 a year — most likely because they were most often found in leadership positions. Middle children were likely to earn the least.

Which kid is likely to grow up and do something that helps the needy?

Middle children aren't born peacemakers and negotiators — they learn it from their place in the family. Often overlooked, middle kids have to learn how to fit in between an older sibling and a new younger one when it comes along. Often middle kids don't feel heard and so they tend to look for attention and bonds outside of the family group, which is why some psychologists explain that they often grow up and enter the helping professions.
