The Global Nappy Index is brought to you by MyVoucherCodes and showcases research conducted in October 2018 which looks at the cost of nappies (diapers) in each of the world's 36 OECD countries.
The price of nappies was obtained from the leading online supermarket in each country and used a comparable pack of nappies. In 33 of the 36 countries, this was a size 4 pack of Pampers Baby Dry. The cost per nappy was calculated based upon the largest available pack size at the time of research. In the other 3 countries, the leading brand was used; again looking at a size 4 pack.
It has been estimated the average child wears 6,000 nappies between birth and the time which they are potty trained; commonly age 3. With this in mind, the 'total' price per country was calculated based upon 6,000 nappies purchased and the annual price assuming 3 years.
All prices were collected in the local currency and converted to GBP (£) on 9th October 2018 using the current exchange rate on xe.com.
