Big data statistics: How much data is there in the world?

In 2024, the global volume of data created, captured, copied, and consumed is 149 zettabytes,according to statista.

By 2025, the global volume of data is projected to rise further to 181 zettabytes by the end of 2025. This growth is driven by the increasing use of IoT devices, real-time data processing, and cloud-based storage.

To put it in perspective, a zettabyte equals 1 sextillion bytes (1,000,000,000,000,000,000,000 bytes), or the equivalent of storing 250 billion DVDs.

Recent analyses indicate that approximately 90% of the world’s data has been generated within the past two years, and according to IDC, the volume of data stored globally is doubling approximately every four years.

But just how much data is there in the world today? Let’s look at some leading studies to understand the numbers and their context.

How Much Data Exists in the World Today?

As of 2024, the global data volume stands at 149 zettabytes.

This growth reflects the increasing digitization of global activities, from consumer applications to industrial operations, including demand for real-time analytics, automation, and efficient data storage solutions, and underscores the need for advanced storage solutions and robust data governance frameworks to manage this unprecedented scale of information.

How Much Data Is Created Daily?

According to the latest estimates from Statista, throughout 2024, approximately 402.74 million terabytes of data are generated daily (equal to approximately 402.74 quintillion bytes – 4.0274 × 10²⁰), encompassing newly created, captured, copied, and consumed information.

How Data is Measured

Data is measured using a hierarchical system of units, starting from bytes as the basic building block. A single byte consists of 8 bits, each representing a binary value (0 or 1).

As data volume increases, it is expressed in larger units for ease of understanding: kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), petabytes (PB), exabytes (EB), and zettabytes (ZB).

Each unit represents a thousandfold increase from the previous one (e.g., 1 TB = 1,000 GB).
For extremely large data volumes- yottabytes (YB), the next unit after zettabytes, are occasionally referenced, though this is not yet practical for most applications.

This system allows for consistent measurement and comparison of data volumes across industries, ensuring clarity when discussing trends in data growth.

Where is All This New Data Coming From?

The world’s data volume has increased dramatically in the past twenty years for several interlocking reasons.

According to Moore’s Law, digital storage becomes larger, cheaper, and faster with each successive year. And with the advent of cloud databases, previous hard limits on storage size became obsolete. Since 1986, the amount of available data storage in the world has increased rapidly, reflecting this new reality:

In the early 2000s, companies such as Google and Facebook harnessed cloud infrastructures to collect massive amounts of user data for customer targeting. Companies around the world soon adopted similar big data tactics.

And as billions of new users gained internet access across the globe, data generation increased enormously.

Fast forward to today, the dramatic growth in global data generation is driven by a range of factors across various domains. From artificial intelligence to social media and the integration of IoT devices into daily life.

Today’s key sources of this new data include:

Adding It All Up: How Much Data Is There in the World?

When estimating the total amount of data in the world, it’s best to break it down into smaller segments. The numbers are staggering: as of 2024, the global datasphere stands at 149 zettabytes, with projections reaching 181 zettabytes by 2025.

But what do these numbers really mean, and where does all this data reside?

Data is created and stored across a wide range of systems, including enterprise servers, cloud platforms, personal devices, IoT ecosystems, and digital platforms like social media and streaming services. A large portion of this data is transient—used and discarded quickly—while the rest is stored for longer-term use in archives, backups, or active datasets.

The distribution of data is also changing – Cloud storage now holds the majority of global data ( approx. 60% of all corporate data is cloud-stored), reflecting the ongoing shift from local storage systems to scalable and flexible cloud environments. At the same time, IoT devices and edge computing solutions reduce latency and bandwidth usage, enhancing real-time data processing capabilities.

But what about those old mainframes, non-networked machines, local hard drives, and all the other unreachable forms of digital data? And what if we include non-digital data: insurance forms, books, and instruction manuals?

The truth is, it’s impossible to factor in some of that data. So perhaps it’s best to look at the estimated 149 zettabytes in 2024 as the lower bound—a minimum estimate for how much data there is in the world.
