Monaco

The principality of Monaco has the highest number of millionaires and billionaires per capita in the world and one of the lowest birth rates. But any moms-to-be can expect eight weeks of leave before and eight weeks after the birth of a first or second child, at 90 percent of earnings. For kid number three or more, that bumps up to 18 weeks after. Dads get 12 days — including Sundays and holidays.
