What this occupation does
Data scientists develop and implement a set of techniques or analytics applications to transform raw data into meaningful information using data-oriented programming languages and visualisation software. The role spans data preparation, modelling, statistical analysis, dashboarding, and stakeholder communication.
The exposure score in context
The ILO 2025 refined Generative AI Occupational Exposure Index places data scientists in the moderate exposure gradient. ILO 2025 places data scientists in the moderate exposure gradient. Routine data wrangling and standard reporting are highly exposed; modelling, feature engineering, and stakeholder interpretation are augmentation-prone but not displaceable at task level.
The mapping uses ISCO-08 code 2120 (BLS-published SOC-to-ISCO crosswalk). The full methodology, including the dominant-match rule for one-to-many crosswalks, is at /methodology/#algorithm.
The top five tasks, classified
The top five O*NET 30.2 tasks for this occupation, each tagged Displaceable / Changing / Growing per the Brookings 2024 task-level rubric. The tag definitions are at /glossary/#displaceable-task, /glossary/#changing-task, and /glossary/#growing-task.
- Changing: Apply feature selection algorithms to models predicting outcomes of interest, such as sales, attrition, and healthcare use. AutoML and AI-augmented feature selection are widely used; final modelling judgement remains human.
- Growing: Apply sampling techniques to determine groups to be surveyed or use complete enumeration bases. Sampling design involves statistical judgement that grows in importance as AI handles more execution.
- Changing: Compare models using statistical performance metrics, such as loss functions or proportion of explained variance. Model comparison is heavily AI-augmented; deployment judgement remains human.
- Displaceable: Develop and implement procedures for cleaning data and handling outliers. Standard data-cleaning is technically and contextually feasible for current generative AI.
- Growing: Present analytical findings to non-technical audiences. Stakeholder communication is augmentation-prone per Brookings 2024 and grows with the volume of analyses.
