TINTON FALLS - A recent study by the Centers for Disease Control and Prevention found that women in the United States are having children later in life than ever before.

The study found that the average age a mother gives birth to her first child has risen from 24.9 years old in 2000 to just over 26 years old in 2014.

Rutgers University sociology professor Deborah Carr says that this finding has an effect on families and the population as a whole.

“Younger women today are less likely to give birth than in the past. We’re actually seeing a drop off in teen birth rates yet at the other end we're seeing a rise in women in their 30s, their upper-30s and even 40s giving birth for the first time,” she says.

Professor Carr says part of this is due to greater access to birth control, as well as women who decide to delay having children so they can focus on school or a career.

Some mothers who spoke with News 12 New Jersey agree with this assessment. Renee Dorski says that she had her first child when she was 30 years old.

"I definitely waited. It's part of life,” she says. “I also think it was part my career…and I was traveling a lot.”

Professor Carr also says that although the population may drop overall, babies born to older parents behave better in school; are more likely to graduate; and have parents who are more stable financially and psychologically.
