The city has rocketed down the list of suburbs for babies born, sitting at 91 in the state for 2019, according to the NSW Registry of Births Deaths and Marriages. Armidale is home to more new mothers, than Tamworth's bustling population.

The department released the official figures on Thursday showing 183 mothers called Tamworth home when they had their baby last year. The list is based on the mother's home address at the time of birth.

The data released shows Armidale nabbed town number 44 on last year's list with 244 new kids born to Armidale mums.

"We were conscious about the recommendations from the UN to have one less child than you would normally have."

Tamworth's apparent baby drought, or lack of boom, is blamed on several factors including the economic and social climate, among other things.

In Ms Cameron's friend circle, she said there doesn't seem to be the feeling that global issues are influencing the decisions of would-be parents.
