Niuean island 163 mail

You're referring to the Niuean island with a population of around 163 people!

You're likely thinking of Niue, a small island nation located in the South Pacific Ocean, northeast of New Zealand. Niue is a self-governing island with a population of around 1,600 people, but it's not the island with a population of 163.

Could you be thinking of a specific island or atoll with a population of 163 people? If you have more information or context, I'd be happy to help you identify the correct island!
