Would you consider yourself the family jester? Relatively easy-going? A wee bit irresponsible?

Chances are you’re the youngest sibling, a new study suggests.

YouGov researchers had 1,783 British adults rate different facets of their personalities, and found that 46 percent of people who were the youngest in their family thought of themselves as the funniest sibling– compared to 36 percent of oldest siblings.

Moreover, 47 percent of youngest siblings felt they were more easy-going than their older counterparts.

Researchers say this at least partially due to the fact that first-born children tend to feel a burden of responsibility that their younger siblings do not. This was corroborated by their discovery that 54 percent of oldest siblings confessed to feeling more responsible – compared to 31 percent of youngest siblings.

It's this deeply ingrained sense of duty, perhaps, that translates to 38 percent of older siblings claiming they are more successful and prosperous than their younger brothers or sisters.

“To some extent age itself, rather than family dynamics, may be responsible for the differing characteristics. Older children, having had more time to get on in life, are more likely to say they are more successful than their siblings,” reads the study.

“But undoubtedly there are family forces at work – parental attention soon shifts onto new arrivals, and first borns may have to learn the ropes themselves. As evidence, elder siblings are more likely to feel more organised and able to prioritise their own lives.”
