New research by IPG Mediabrands agency Initiative finds that fathers ages 25 to 34 are more optimistic about the economy and more ambitious than men without children. That makes them a market that could be highly receptive to positive messages and open to discretionary spending. Indeed, 67% of millennial dads are confident about their personal economic situation compared with 59% of non-dads and 58% of mums, while 45% feel positive about the state of the economy compared to 40% of men without children.
