Manhattan, reports Nerdwallet.com, is by far the most expensive place in the nation to raise a child. The financial website calculated that it costs parents more than $540,000 for housing, food, transportation, health care, education and miscellaneous expenses, to rear a New Yorker until age 18. But that figure may be quite conservative, considering 14 years tuition at a top private school in New York alone costs more than $600,000.
