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

- 4.5% of global deaths are attributed to ambient air pollution (WHO)
- 5.1% of global deaths are attributed to household air pollution (WHO)
- 700+ million people worldwide lack access to electricity (global figure for 2022)
- 2,600 terawatt-hours global electricity generation in 2022 (IEA estimate)
- $5.1 trillion global health expenditure in 2022 (current health expenditure worldwide)
- ~$100 trillion global GDP in 2023 (World Bank estimate, current US$)
- $3.4 trillion worldwide foreign direct investment flows in 2022 (global FDI inflows)
- 55% of the global population lives in urban areas as of 2022 (share urban, UN DESA)
- 2.37 billion people were in the middle class worldwide in 2020 (OECD/World Bank-consistent estimate)
- 66.0% of the world’s population uses the internet (2024 estimate, ITU)
- 3.3 billion unique mobile subscribers worldwide as of 2022 (GSMA)

- $610 billion global software market revenue in 2023 (Gartner estimate)
- 61.3% of the world’s population uses social media (2024, DataReportal)
With diabetes and air pollution rising alongside unequal electricity access, global health spending climbs yet progress remains uneven.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
