What percentage of the population has never owned a pet?

It's impossible to give an exact percentage of the population that has never owned a pet. There's no global database tracking pet ownership, and cultural norms, financial situations, and personal preferences all play a role.

Here's what we can say:

* Pet ownership is common: Many studies indicate that the majority of people have owned a pet at some point in their lives.

* Variations exist: Pet ownership rates differ significantly by region, age, income, and lifestyle.

* Factors influencing ownership: Lack of space, allergies, financial constraints, travel lifestyles, and personal beliefs are among the reasons some people may not own pets.

If you're interested in specific regions or demographics, you might find research papers or surveys that address pet ownership rates in those areas.
