I know that the answer to the question "Which age group had the largest population in 2000?" is in "As of 2000[update], children and teenagers (0–19 years old) make up 15.1% of the population, while adults (20–64 years old) make up 65% and seniors (over 64 years old) make up 19.9%.". Can you tell me what it is? 


adults (20–64 years old)
