World statistics can be surprisingly uneven, with 1.16 billion adults living with diabetes alongside hundreds of millions still without electricity. At the same time, internet use has reached 66.0% of people, yet air pollution continues to push health costs and excess deaths higher. These contrasts are exactly what makes global data worth looking at closely.
Key Takeaways
