Pavel Prikhodko, Ph.D. Machine Learning

Some people believe in Santa Claus, and some people don’t. According to a survey conducted in the U.S. in November 2016, 49 percent of people said they firmly believe in Santa Claus. During the survey, 50 percent of respondents said Santa Claus is not real, while 9 percent of people were not sure about his existence.

If we break it down by age group, 28 percent of respondents aged from 18 to 29 years said they firmly believe in Santa; about 64 percent of respondents in the same age group said that Santa Claus is not real. The number of people aged between 30 and 44 years who firmly believed in Santa Claus was 35 percent in 2016, while the number of people who didn’t believe was 55 percent. Around 11 percent of similarly-aged people were not sure about the question.

More than 50 percent of the respondents aged 45 to 64 years said that they firmly believe in Santa, while only 41 percent of the people in this group said, “Santa Claus isn’t real!” The number of older people who believe in Santa Claus was surprisingly impressive among people over 65 years old: 47 percent! Only 46 percent said that Santa isn’t real at all.



According to the information showing the results of a 2011 survey among American adults regarding the age at which they stopped believing that Santa Claus is real, about 18 percent of the respondents said they stopped believing in Santa when they were eight years old. About 16 percent of the respondents stated that this remarkable moment of disbelief came at 10 years of age. Approximately 12 percent stated they stopped believing in Santa Claus when they were seven years old, while 7 percent of respondents said the stopped believing in Santa when they were teenagers.
