How many onboarding quizzes ask demographic questions like age or gender?

The finding

Demographic questions appear in 24 of 119 quiz apps, tied with goal questions (24) and just above habit questions (23).^{source[1]source[2]} The demographic set covers age, gender, weight, height, and date of birth — fields that materially change a fitness, nutrition, or medical plan.

This question type concentrates in Health & Fitness, which is both the largest quiz category and the deepest-quiz vertical (avg 6.2 screens).^source[3] In those apps, weight and height aren't vanity fields — they feed calorie targets and program calibration.

How to apply it

Ask a demographic question only when the answer changes something the user will see. Weight and height in a fitness app pass that test; age in a generic productivity app usually doesn't.

Because demographics feel personal, place them after the goal question so the user already understands why you're asking. A goal-first order gives the demographic fields a rationale and reduces abandonment.

Caveats

The count is deduped by company from vision descriptions and is a lower bound — a demographic screen counts only when the vision text names age, gender, weight, height, or DOB.^source[1] Apps that collect demographics via native pickers the vision model didn't describe will be missed, so true adoption is likely higher.
