In the last two years, what percent of the data in the world was generated?

• A. 80 percent
• B. 90 percent
• C. 60 percent
• D. 70 percent

Answer: (B)

The main idea is that data generation has exploded in recent years, so most of the data that exists today was created very recently. Industry estimates have long stated that roughly nine-tenths of all data was generated in the last two years. This reflects the enormous growth in digital activity—from social media and online transactions to sensor streams, logs, cloud services, and AI training—which produces data far faster than older data can be absorbed or stored. Because new data is created at such a rapid pace, the share of data generated in a two-year window ends up around 90%, making that figure the best match. The smaller percentages would imply a much smaller recent contribution, which doesn’t align with how rapidly data has been growing.
