The Cash Product Office of the Federal Research System has released the findings from their 2019 Diary of Consumer Payment Choice (Diary). A demographically-representative sample of 2,873 individuals participated in the study and reported all of their payments and transactions over three consecutive days, staggered throughout October 2018.
Some highlights from the study are:
Cash is most popular by younger and older age groups.
The use of cash has been declining in all age groups except under age 25
Cash is used most often from smaller purchases.
Participants' 2018 payment preferences remained similar to those stated in 2017. Most participants prefer to pay with debit cards (42%), while the next largest group prefer to pay with credit cards (29%); both shares remain unchanged from 2017. Cash is the third most preferred payment method, with 22% of participants reporting it as their primary way to pay for goods and services
