Mrs Jauncey moved to Jersey with her husband who was born and raised there.
She said some aspects of bringing up her children on the island were "really great", such as how safe it was and the system of state-supported private schools.
However, she added: "Families and individuals with children are really not prioritised in Jersey culture".
"There's a work culture that is unfairly weighted on the side of the employer... and the fact that our culture as an island is very much directed towards the elderly who have a large amount of the voting power."
She said the island was "focused on the people who are shouting the loudest", adding that often older people were the ones with the time and energy to do so.
