It can sometimes be hard to comprehend the volume of data creation the world is generating every day. One data consultancy firm has estimated that the amount of data generated by the year 2020 will equal 44 zettabytes.
Last year, IBM estimated that we create 2.5 quintillion bytes of data every day.
This data is coming from just about everywhere—every online interaction creates a stream of data—from shopping purchases, to reading online content, to activity on social media, to clicks on smartphones and mobile devices, like tablets. Social media is a huge source of what is called “unstructured data,” one of the three category types of Big Data. The other two are structured data (database data), and semi-structured data (also sometimes called hybrid data or multi-structured data).
Here are some statistics about unstructured Big Data generation:
- Around 15.2 million text messages are sent every minute.
- Users upload approximately 4 million hours of content to YouTube, every day.
- People watch around 5.97 billion hours of video daily on YouTube.
- Internet-connected devices (IoT) represent a large stream of data, which is increasing rapidly.
- There are, on average, 4.3 billion Facebook posts every day, generated by the approximately 1.32 billion daily active users.
- Those posts generate 5.75 billion “likes” every day.
- Roughly 456,000 Tweets are posted every minute.
