The Internet of Things (IoT) has rapidly evolved from a futuristic concept to an integral part of our everyday lives. As more devices get embedded with sensors and connectivity, they collectively form a vast, powerful network that is reshaping businesses and societies.
To comprehend the scale and impact of the IoT revolution, we dive into some of the key statistics and trends surrounding this emerging technology:
The Staggering Scale of Connected Devices
The number of connected IoT devices has skyrocketed in recent years, with projections of continued massive growth on the horizon:
- 15.14 billion – The number of active IoT devices worldwide as of 2023, according to IoT Analytics. This marks a substantial increase from 13.14 billion in 2024.
- 29.42 billion – The projected number of active IoT devices globally by 2030, per Statista. The IoT ecosystem is ramping up quickly.
- 871 million – The number of smart home devices shipped globally in 2024, up from 715 million in 2021, according to IoT Analytics. Products like smart bulbs, security cameras, and voice assistants are becoming mainstream.
- 1.23 billion – The estimated number of smart home devices that will ship worldwide by 2027, predicted by Gartner. Smart product capabilities like AI integration and home automation will further accelerate adoption.

IoT Adoption Spreads Across Industries
IoT is being rapidly adopted across major industries globally to enable process improvements, cost savings, enhanced customer experiences and new revenue opportunities:
- 67% – The proportion of current IoT usage concentrated in North America, Western Europe and China, per Bain & Company. These regions are leading innovation and integration of IoT in manufacturing, agriculture, utilities, healthcare and more.
- 44% – Percentage of companies in the US that are using IoT technology as of 2022, according to InformationWeek. IoT enables predictive maintenance, inventory optimization, quality control and more based on real-time data from connected equipment and assets.
- 158.1 billion – The projected size of the global IoT healthcare market by 2022, according to Statista. IoT is enabling remote patient monitoring, connected imaging, asset tracking and telehealth solutions to improve care delivery.
- 10% – The estimated boost IoT can provide to U.S. GDP through efficiencies in supply chain, industrial operations and infrastructure management, per Goldman Sachs. The economic impact potential is staggering.
The Data Deluge from Billions of Devices
As the number of connected endpoints expands exponentially, the amount of data generated is unprecedented and transformative:
- 152,000 per minute – The number of new IoT devices connecting to the internet every minute by 2025, estimated by IDC. As adoption grows, the influx of data will be massive.
- 73.1 zettabytes – The projected amount of data that will be generated by IoT devices per year by 2025, according to Seagate. This creates huge opportunities for analytics and intelligence.
- 41% – The share of IoT‘s $3.9 trillion total value that will come from data-driven operational efficiencies, per McKinsey. Data analytics is key for value creation from IoT.
- 2% – The minuscule percentage of current IoT data that is encrypted, as per Gemalto. With most data transfers unprotected, businesses must make security a priority.
The Emerging Risks and Challenges
The massive growth of IoT also introduces new cybersecurity threats and risks that cannot be ignored:
- 13 million – The number of IoT malware attacks that occurred globally just in June 2022, per SonicWall. As devices proliferate, vulnerabilities will continue to be exploited.
- 21 minutes – The average time it takes for an unprotected IoT device to be attacked once connected to the internet, according to Microsoft. Security must be baked into IoT devices from the design stage.
- 20.99 million – The number of times the password ‘admin‘ has been used on IoT devices over a 45-day period, per Cujo AI. Better security standards and user education are clearly needed.
- 48% – The percentage of businesses that do not know whether their IoT devices have been breached, according to Software Advice. Visibility and monitoring tools are crucial.
Key Takeaways
The IoT revolution is well underway, with over 15 billion connected devices deployed worldwide today and projections of nearly 30 billion by 2030. This massive growth is creating opportunities in data analytics, automation and business model innovation that companies need to tap into. However, security and privacy risks cannot be ignored. Organizations must make resilient architecture, encryption and user education a priority as they integrate IoT. By approaching IoT thoughtfully, businesses can unlock immense value from this connected future that is already here.
