Synthetic data
Artificially generated data intended to statistically resemble a real dataset without containing actual real records. Synthetic data carries a formal, testable privacy guarantee only when the generative model producing it was itself trained under differential privacy with a stated epsilon; otherwise its privacy properties are unquantified. (see Topic 4.5)
Defined in 7 GAGE programs, which carry 9 distinct definitions of it. The wording above is taught in Certified AI Data Governance Professional (CADGP).
How each discipline defines it
The same term does different work depending on who is using it. These are the definitions as each program teaches them, unedited.
Artificially generated data intended to statistically resemble a real dataset without containing actual real records. Synthetic data carries a formal, testable privacy guarantee only when the generative model producing it was itself trained under differential privacy with a stated epsilon; otherwise its privacy properties are unquantified. (see Topic 4.5)
Training or fine-tuning data generated by an algorithm rather than collected from real-world sources. A legitimate acquisition option that reduces most personal-information consent questions but remains subject to the same data-quality obligations as any training data, and can carry its own licensing and memorization risks.
Data that was manufactured by a process rather than measured directly from a real person, transaction, or event. It is designed to resemble real records statistically. It comes in three practical families: rule-based augmentation, generative-model output, and simulation.
Data generated by an AI to fill gaps in real data; useful when real data is scarce, but it can amplify the flaws of the model that produced it (including representation gaps from the original collection), so it is best used cautiously and verified before relying on it.
Records generated by a model trained on a real dataset so that no individual's actual record is disclosed, only a statistical likeness of the population. Not proof of anonymity by itself; a generator can memorise and reproduce a near copy of an unusual real record.

Where it shows up at work
A definition is where Synthetic data starts. The lessons above teach it inside the competencies below, which are what job descriptions ask for and what the GAGE credential records. Every link here is drawn from the same careers map that builds a role's readiness check.
Profiles data, sets rules and thresholds, monitors, assigns issues to owners, and knows when data is not fit to train or run a model.

How job descriptions say it
Postings rarely use the textbook word. These are the phrases the careers map reads as asking for the competencies above.
Where the frameworks place it: EU AI Act Article 10; ISO 8000; GDPR; CCPA/CPRA.
One interview question about it
Which data quality rules would you monitor for a model in production, and what happens when one fails?
Asked of candidates for data quality rules and monitoring. Answering it in your own words is exactly how a GAGE topic is passed, and the credential records the pass where an employer can check it.
If you come from another field
Some backgrounds already carry this competency, and the readiness check gives credit for it.
- Data analysis, stewardship and business intelligence carries it as work you can show: Quality rules and profiling results are your artifacts.
- A data science, statistics or analytics degree carries it as a claim to back up: Data quality rules are familiar; monitoring them in production is new.
- Privacy and data protection carries it as work you can show: Privacy assessments and lawful-basis records are your work product.
