The new kids on the block don’t seem to have as much fun as their older siblings.
A new study published in the journal Science suggests kids’ favorite exercise books have been around longer than the books themselves, and the books are far less popular than they once were.
The study, conducted by a team at the University of Rochester and published in a recent issue of Science, looked at the sales of more than 600 exercise books sold in 2012 by various retailers including Amazon, Barnes & Noble, and Best Buy.
“It’s a very large number of books,” said lead author Jonathan LeBlanc, a professor of psychology at the College of William and Mary and co-director of the Center for Applied Developmental Psychology at the university.
LeBlan says the study doesn’t suggest kids’ exercise books are any more popular now than they were when they were first published in 2006.
The researchers compared the sales figures for the most popular exercise books from 2006 through 2016.
They found that the sales numbers of exercise books published in 2018 fell by more than 40 percent from the numbers for books published the year before.
“We’re seeing the decline of the older books that were popular for kids and young adults,” LeBlans co-author of the study, Elizabeth S. Doolan, told Vice News.
“This is really interesting because we had a lot of older books on the market, but not so much of the newer ones.”
The biggest change in the market for exercise books was in the number of new products on the shelf.
Leblanc and Doolann said the rise of online shopping may have made the younger generation want more books, but that was largely a byproduct of the fact that kids are getting more comfortable online.
“If you have an opportunity to interact with someone on a different platform and have that interactivity in a way that was really fun and engaging for them, then that’s where the opportunity to purchase books has gone,” Leblan said.
“And so that’s the thing that we think is driving the increase in younger kids’ desire to purchase exercise books online.”
A lot of people still get exercise books through the mail, Leblans co
