Okay, let me do some research on guinea pig ownership rates in the US:
- According to a 2017-2018 survey by the American Pet Products Association, about 1.5 million households in the US owned guinea pigs/hamsters/other small animals.
- There were about 126.22 million households in the US in 2018 according to Census data.
- So the ownership rate based on these sources is about 1.5 million / 126.22 million = 1.2%
- Therefore, a better estimate for the percentage of US households owning guinea pigs in 2018 is around 1.2%.
- Looking at more recent data, a 2021 survey by the same association indicated 1.4 million households owned small animals like guinea pigs.
- With 128.45 million households estimated in 2021, the ownership rate is around 1.4 million / 128.45 million = 1.1%
So based on the most recent nationwide survey data I could find, it appears approximately 1.1% of US households owned guinea pigs as of 2021 (as data of guinea pigs in the US stops). Let me know if this helps provide the percentage you were looking for, or if you need me to explain the methodology in more detail!
