Honest projection · estimated
Data Created Today (est.)
A projection of how much digital data the world has created, captured, copied and consumed since midnight UTC, ticking at the most recent complete-year total — about 149 zettabytes in 2024, the standard IDC Global DataSphere figure — spread evenly across the year. A terabyte is a thousand gigabytes; the world now makes roughly four hundred million of them every day. Most is transient (video streams, sensor feeds) rather than stored forever. A yearly average made visible, not a live ledger.
About this number
This is an honest projection, not a census. It is computed by carrying a published figure forward at a known rate over real elapsed time — ≈ 4,700 TB/sec (≈408m TB/day), from IDC Global DataSphere — about 149 zettabytes created worldwide in 2024, spread evenly across the year. The source is IDC — Global DataSphere (2024). The true value is known only to within a margin; this is the running estimate, and we label it as one.
