From Richer Investment Diaper Consulting Services:
The volume of diapers sold in the United States alone in year 2006 will be close to 18.6 billion units, around 20.4 billion units will be sold in Europe and 4.9 billion units will be sold in Mexico in 2006.
No one takes longer at potty training than American babies. When you take into account this fact, more diapers are used per baby in the US in comparison to Europe or even Japan. As a matter of fact, American babies use diapers much longer than they used to do a decade ago. Probably the result of the “psychological stress” campaign associated to the practice of potty training. It is also a very convenient excuse for not having to pay much attention to your baby and let him learn when he pleases. Of course if we all can sell more diapers we can tell every parent that they should not rush the baby’s development to avoid a permanent “psychological trauma” (here he inserted a smiley face)
I forecast that this trend of extending the use of the diaper will continue in the near future in the USA, probably the winner of this strategy will be the training pant, but it could also mean increased sales and maybe even the launch of a size 7 diaper. I believe this trend will remain mainly in the USA and maybe a few of the Western European countries. For the rest of the world, “the psychological stress argument” will have no impact as disposable income will force every parent to become their own baby’s therapists, but they will push the baby to learn quickly with potty training and save the money.
Once you take into account all available data, we can estimate a total number in a range of 3,700 to 4,200 diapers used during the entire life of the baby.
