Females tend to send the most text messages. They send abut 4,050 a month - compared to teen males, who send about 2,539 a month.
Some teens are surprised the figure isn't higher.
"I send around 5,000 a month," said Celine Condevaux, a 15-year-old.
The next age group studied by Nielsen is young adults age 18-24. They send about 1,630 texts per month.
Dr. Kevin Everhart with University of Colorado Denver says teens sending thousands of texts a month isn't necessarily a bad thing.
"I wouldn't anticipate anything negative coming out of this," he said. "I think the difference communicating through text or by phone or in person shows some qualitative differences [but the differences aren't bad]."
Teens say they like to text because it's simpler than having a face-to-face conversation with someone.
"It might have less meaning but it's quicker and it just takes a lot less time," Celine said.
The study shows teen texting habits increased by 8 percent since 2009. Researches expect that figure to rise in 2011.
