Data Analytics: Foundations to Practice · Types and Sources of Data
First-, Second-, and Third-Party Data
Where data originates shapes both how reliable it's likely to be and how much control an organization actually has over its future availability. This chapter covers the three tiers.
First-party data is collected directly by an organization from its own customers or users, such as a company's own website analytics, purchase history, or customer service records; this is generally the most reliable and most fully controlled data tier, since the organization directly defines exactly how it's collected and retains full, ongoing rights to use it.
Key Takeaways
- First-party data is collected directly by an organization from its own customers, generally the most reliable and fully controlled tier.
- Second-party data is another organization's first-party data shared through a direct partnership, extending reach with more transparency than third-party data.
- Third-party data is aggregated and sold by a broker with no direct relationship to the original individuals, offering scale but less transparency and reliability.
- First-party data has become increasingly valuable as privacy regulation restricts third-party data availability, since it's both reliable and less exposed to external restriction.
