There is currently no fixed date and age range for Generation Z, but most sources cite the mid-to-late 1990s as the starting birth years and early 2010s as the ending birth years. Generation Z's overall date and age range has frequently varied over the years. For instance, the Oxford Living Dictionaries in 2019 describe Generation Z as "the generation reaching adulthood in the second decade of the 21st century." On the other hand, the Oxford Living Dictionaries in 2021 describe Generation Z as "the group of people who were born between the late 1990s and the early 2010s, who are regarded as being very familiar with the internet." The Federal Reserve Bank of St. Louis in 2019 identify 1995 as Generation Z's starting birth year. Conversely, the Federal Reserve Bank of St. Louis in 2020 identify 1997 as the starting birth year.
