* Region: Pet ownership rates vary significantly by country and even within regions.
* Demographics: Factors like age, income, and household size can influence pet ownership.
* Data source: Different surveys and studies may use different methodologies, leading to varying results.
However, here's what we know:
* Globally: Pet ownership is very common. According to the American Veterinary Medical Association (AVMA), around 67% of U.S. households own at least one pet. This percentage is likely to be higher in developed countries and lower in developing countries.
* Increasing trend: Pet ownership has generally been on the rise in many parts of the world, with more people choosing to treat pets as family members.
Therefore, while it's hard to say for sure, it's reasonable to assume that a significant majority of households worldwide own at least one pet.
