Hobby Rarity Calculator — How Unique Are Your Interests?

What you do in your free time says a lot about who you are — and some hobbies are far rarer than others. The Avortas Interests and Hobbies Calculator lets you select from over 20 activities, musical instruments, and pet types to see how common or unusual each is based on global participation surveys from Statista, Gallup, and census data.

How Hobby Rarity Is Measured

Each hobby has a global participation percentage. Cooking is practiced by 41% of adults — the most common leisure activity. Reading follows at 36%, gaming at 28%. Creative writing and collecting sit at just 8%, and volunteering at 6%. Niche hobbies like falconry fall below 0.1%. Selecting multiple hobbies shows each one's rarity with visual bars for easy comparison.

Musical Instruments

Singing is the most common musical ability at 12%, followed by piano (8.5%) and guitar (7.2%). Classical instruments like violin (2.1%), flute (1.2%), and saxophone (0.9%) are much rarer. Playing multiple instruments compounds your rarity — guitar plus saxophone is shared by fewer than 1% of people worldwide.

Pet Preferences

Dogs lead at 33% of households, cats at 23%, fish at 12%. Exotic pets — reptiles (2%), rabbits (2%), birds (6%) — are statistically unusual. About 35% have no pets. Your pet choices add another data point to your uniqueness profile.
