A new study out of Brigham Young University says birth order does indeed decide how older siblings will fare during their lifetimes. According to the study, first-born children receive more time with their parents between the ages of 4 and 13 than the next sibling during this same age range. Researchers believe this extra attention helps children get more education, make more money, have higher IQs.
“We’ve known for a long time that eldest children have better outcomes, and these findings on quality time provide one explanation why,” said Brigham Young University economics professor Joseph Price, who used data from the American Time Use Survey, a federal government study involving 21,000 people.
Price recommends that parents spend more quality time with younger children.
