Introduction — why compare private vs public health insurance in 2025?
Every country structures health insurance differently. Some rely heavily on public systems (government-funded), while others emphasize private markets (individual or employer-based).

This guide explains how private and public health insurance work, compares them across the US, Canada, UK, and Australia, and highlights the pros and cons of each.
What is public health insurance?

- Covers hospital visits, doctor care, emergency treatment, and preventive services.
- Often universal — available to all citizens and residents.
- Low or no out-of-pocket costs, but waiting times may be longer.
What is private health insurance?
Private health insurance is purchased through employers, private insurers, or directly by individuals.
- Covers services not fully included in public systems (e.g., dental, vision, private hospitals, shorter wait times).
- Higher premiums, but faster and broader access.
- Often used as a supplement to public systems in countries like Canada, UK, and Australia.
