Millennials (also known as Generation Y) are typically defined as the generation of people born from 1981 to 1996 (according to many sources). The United States Library of Congress and the federal government of Canada (Statistics Canada) have both officially cited the 1981-1996 birth range for Millennials as of 2022. These federal agencies state that 1996 is the last birth year of the Millennials. There are also a number of sources that describe Millennials as 1980–1994. These include Australia's McCrindle Research as well as psychologist Jean Twenge. A number of other references and sources say Millennials have birth dates from 1980–1995. A few researchers and demographers use 1980 as the starting birth year and as late as 2001 as the ending birth year.
People in this generation are sometimes called Echo Boomers because of the high birth rate during this period. The high birth rate almost exceeds that of the Baby Boom period after World War II. Some of the famous celebrities who are from Generation Y include Harry Styles, Katy Perry, Britney Spears, Natasha Bedingfield, Christina Ricci, Anna Chlumsky, Joshua Wong, Beverley Mitchell, Kim Kardashian, Lady Gaga, Kate Bosworth, Justin Bieber, Caroline Sunshine, Mandy Moore, Tom Holland, June Diane Raphael, Macaulay Culkin, Sophie Turner, Miley Cyrus, Mara Wilson, Hailee Steinfeld, Colbie Caillat, Zendaya, Post Malone, Dua Lipa and Avril Lavigne.
