Final answer:
Baby Boomers make up the largest portion of pet owners.
Step-by-step explanation:
The Baby Boomers generation makes up the largest portion of pet owners.
The Census Bureau reports that as of 2013, 20% of the U.S. population was over 60 years old, which means that almost 63 million people are reaching an age when they will need increased medical care. This suggests that there are a significant number of Baby Boomers who may own pets.
Additionally, a study by the Pew Research Center found that Baby Boomers were more likely to own pets compared to other generations. The study indicated that 74% of Baby Boomers owned pets, while only 51% of Generation X and 42% of Millennials owned pets.
