A citizen data scientist is a business professional who uses self-service analytics, automation, and AI tools to generate insights, build simple models, and contribute to data-driven decision-making without formal training in advanced statistics or computer science. Unlike data scientists, who specialize in complex modeling, a citizen data scientist applies domain expertise with accessible tools such as drag-and-drop machine learning, automated model builders, or generative AI platforms. Organizations increasingly empower citizen data scientists to extend the reach of analytics, closing the gap between technical data teams and business users. This democratization of analytics enables faster insights, but it also requires governance, training, and oversight to ensure accuracy, consistency, and compliance.
