- The declining U.S. birth rate is hurting companies like Procter & Gamble and Kimberly-Clark.
- The $12.6 billion diaper business dropped at an annualized rate of 0.3 percent from 2012 to 2017.
- Still, diaper makers can bounce back through innovation and new forms of distribution.
Baby making in the U.S. is on the decline, and the makers of diapers and bottles are feeling the pinch.
The U.S. birth rate dropped to a historic low last summer, as would-be parents pushed back parenthood. Meantime, the $12.6 billion diaper business dropped to an annualized rate of 0.3 percent from 2012 to 2017.
"This could be parents delaying or that drop could be here to stay," said Jason Dorsey, president of the Center for Generational Kinetics. "We won't know for another five years, but companies can't wait that long to find out."
The slowdown could be attributed to any number of factors: focus on work, recession fears or student debt.
The impact of millennials having children later or, in some cases, not at all, is already having an effect.
Kimberly-Clark, the maker of Huggies diapers and Kleenex tissues, on Tuesday announced it will cut about 13 percent of its workforce globally in a bid to reduce costs as sales wane. It pointed to the lower U.S. birth rate as one of the challenges confronting the company in its Tuesday call with investors.
Pampers-maker Procter & Gamble, which also announced earnings Tuesday, reported a 1 percent drop in its baby, feminine and family care business. That segment, which also includes wipes and pregnancy tests, has declined or stayed flat on a yearly basis since 2014.
The pain has proliferated beyond diaper makers. Edgewell Personal Care, the maker of Playtex baby bottles, has seen sales of its infant feeding products decline. Johnson & Johnson has watched its U.S. baby business, which includes baby oil, bubble bath and nursing pads, drop as well.
"Big brands right now need to adapt, because a delay in having children or a decline poses a significant material threat to their core business," Dorsey said.
The diaper business remains viable, and any business that requires frequent repeat purchases is desirable. But companies need to make and deliver products the way mothers want them to.
Innovation has largely been driven by upstarts. Brands like Honest Co. and Seventh Generation have shown there is an appetite for organic diapers (though Honest ran into labeling issues). Several retailers have demonstrated the appeal of an online subscription diaper business.
Companies also can extend their product lines, making different products for babies or focusing on toddlers rather than newborns.
J&J plans on relaunching its baby care products this year with new formulations and packaging, the company said during its earnings call.
Kimberly-Clark told investors Tuesday it has a number of innovations it is planning on unveiling, including diapers with improved protection and fit.
Meantime, as the number of adults older than 65 grow, diaper markers can double down on their offerings for the incontinent. Roughly 31 percent of all diaper sold in the U.S. were adult diapers, according to data provider IBISWorld.
