From Novice To Data Hero: Top Resources For Becoming A Citizen Data Scientist
It is estimated that 90% of the world's data was generated in the last two years alone (Sources: Statista, Bernard Marr & Co.) This figure has increased by an estimated 74x from just 2 zettabytes (2 bn GBs) in 2010 to 129 zettabytes (140 bn GBs) in 2023. Yes, that is a HUGE number!

With that much data being generated, data literacy has become an essential skill, empowering individuals to navigate, interpret, and harness this vast sea of information for informed decision-making and to protect their digital footprint in an increasingly data-driven world.
But First, What is a Citizen Data Scientist
This is a 2-part blog series on the topic of Citizen Data Scientist. In part 1, we discussed in detail the emergence of this relatively new role in many large organizations, the genesis behind this trend, the challenges this role faces, etc.
Citizen Data Scientist = Business expert + Data Scientist - PhD. degree in data
The Decentralization of Data Expertise
Data is rapidly becoming a universal artifact in every team across organizations. There's a growing trend of data teams becoming decentralized, with each functional team requiring its own data expert. These experts possess the skills to work with and analyze data for quick decision-making without relying heavily on a centralized data science team. This shift reflects the increasing importance of data literacy across all business functions. As a result, many are taking on the role of citizen data scientists within their teams, bridging the gap between domain expertise and data analysis.
