Synthetic data is transforming market research with scalable, private, and cost-effective solutions, but fidelity and utility must be rigorously benchmarked.
Synthetic data in market research refers to artificially generated data that mimics real-world data. This data is created using algorithms and statistical models to simulate the characteristics and patterns found in actual data. The primary purpose of synthetic data is to provide a viable alternative to real data, especially when real data is scarce, sensitive or difficult to obtain. The following are some key points about synthetic data in market research:
1. Privacy and security: Synthetic data can help protect privacy and comply with data-protection regulations, as it does not contain any real personal information. This is particularly important when dealing with sensitive customer data.
2. Cost-effective: Generating synthetic data can be more cost-effective than collecting real-world data, especially in large quantities. It can also save time and resources.
3. Testing and validation: Synthetic data can be used to test and validate market research models and tools before deploying them in real-world scenarios. This helps in refining methodologies and ensuring accuracy.
4. Scalability: Researchers can generate large volumes of synthetic data to simulate various market conditions and scenarios, which might be impractical with real data due to limitations in availability and cost.
5. Bias reduction: Synthetic data can be designed to reduce biases that might be present in real-world data, providing a more balanced and comprehensive view for analysis.
6. Innovation: It helps researchers experiment with new ideas and approaches without the constraints of real-world data limitations, fostering innovation in market research techniques. Overall, synthetic data is a powerful tool in market research, enabling researchers to overcome challenges related to data availability, privacy and cost while enhancing the robustness and reliability of their analyses.
The growth of synthetic data has been significant in recent years, driven by a number of factors and advancements in technology, some of which are listed below:
Synthetic data has become a critical asset in artificial intelligence and machine learning applications, providing alternatives to real-world datasets that are privacy-preserving, scalable and legally compliant. As access to the real-world datasets is often constrained by privacy and regulatory laws, high data-collection costs and biases, synthetic data presents a viable alternative, generated through probabilistic models, deep generative networks or rule-based simulations.
The growth of synthetic data is reflected in significant investments and developments, such as Accenture’s investment in Aaru (a startup leveraging synthetic data to create AI-driven predictive model), NVIDIA’s omniverse using synthetic data to train autonomous vehicle models with virtual road scenarios, Meta using synthetic data for improving computer vision models, AWS and Google Cloud’s synthetic data initiatives and the European Commission’s AI Act that promotes privacy-preserved AI, encouraging the adoption of synthetic data in regulated sectors such as healthcare and finance.
However, ensuring the quality of synthetic data is crucial for maintaining model performance and compliance with regulatory requirements. To ensure quality, a number of benchmarking methodologies have emerged, from classical statistical tests to adversarial attack resilience assessments.
Synthetic data is being used increasingly in market research and intelligence due to its ability to address a number of challenges associated with real-world data. “By 2027, synthetic data will replace at least 20% of real consumer data used for predictive analysis in market research industry” , according to the Forrester Research Report 2024. A transformation is on the horizon for the market research sector, driven by synthetic data, as traditional data-collection methods such as surveys, observational studies and interviews often suffer from response biases, high costs and time constraints.
One of the most profound transformations is in turnaround time in delivering insights, as research tasks such as survey designing, data cleaning and fieldwork, which used to take weeks to complete, can now be done within hours using AI-driven synthetic modeling. Generative AI (GenAI) is accelerating insight deliverability by curating survey-ready responses that depicts human behavior, helping companies test products concepts, communication and ad creative in real time, according to a study by Harvard Business Review.
Synthetic data is also being used increasingly for mimicking hard-to-reach audiences such as niche populations, sensitive demographics and low-incidence segments. GenAI tools now enable researchers to simulate large-scale response of niche groups, expanding the scope of insight without requiring significant financial outlay.
Synthetic data is also transforming the way tracker studies and longitudinal research are conducted by simulating responses across time intervals and reducing reliance on repeated fieldwork while maintaining trend continuity. This could prove beneficial, especially to sectors that requires responsive and robust tracking such as FMCG.
One of the most important usages of synthetic data in the market research sector is scenario testing; rather than simply reporting on what has happened, researchers can now model what might happen. This predictive capability enables brands to frame and test marketing or product strategies, pricing models or user journeys before committing resources, providing stress-free experimentation.
However, amid all the excitement, industry leaders are emphasizing the need for rigorous oversight and data governance. Synthetic data must be audited for realism, representativeness and potential biases; thus, it is important to benchmark their quality and performance.
Let’s now understand the technical foundation of synthetic data and how quality benchmarking could be done efficiently.
a. Generative adversarial networks (GANs): GANs are widely used to generate synthetic consumer data, such as demographic profiles, purchase demographic profiles and online behaviour patterns, when trained on real consumer data.
b. Variational autoencoders (VAEs): These are effective for generating synthetic data with complex distribution, such as multi-modal consumer preferences, and are generally used for simulating diverse market segments.
c. Agent-based modeling (ABM): ABM simulates individual agents, such as consumers, and their interactions with a market environment; thus, it is valuable for modelling dynamic market behaviours, such as the impact of pricing changes.
a. Differential privacy: This ensures that individual data points cannot be re-identified by adding controlled noise to synthetic data. It is beneficial for financial institutions, healthcare and market researchers, where datasets often contain sensitive consumer information.
b. K-anonymity and L-diversity: These technologies group similar records and ensure that synthetic data cannot be traced back to specific individuals, maintaining diversity within each group.
c. Federated learning: This technique enables multiple parties to train models on synthetic data simultaneously without sharing raw data, maintaining data utility while enhancing its privacy.
Benchmarking synthetic data quality in market research is essential to ensure that the generated data is reliable, accurate and useful for analysis. The following are some key aspects and methods to consider when benchmarking synthetic data quality:
1. Fidelity metrics: These measure how well synthetic data replicates real-world data in terms of statistical properties. Key metrics include the following:
