Data brokers not only collect personal information but also create predictive profiles about individuals, which can lead to privacy concerns and potential misuse of data.
Data brokers have become a significant part of the digital landscape, collecting and analyzing vast amounts of personal information. They assign labels that predict various aspects of individuals’ lives, including health, finances, and even religious beliefs, based on their online behavior and purchasing habits. This information is then sold to businesses, often without the individuals’ knowledge or consent.
Most people are aware that data brokers gather personal information, but many do not fully grasp the implications of this practice. Beyond merely compiling facts, data brokers utilize algorithms and cross-reference records from multiple sources to categorize individuals. These categories are designed to predict interests, circumstances, and behaviors, which can include sensitive details about health, financial status, and potential vulnerabilities.
While some classifications may seem innocuous, others can reveal deeply personal information that individuals never intended to share. The profiles created by data brokers can be sold or shared with businesses that individuals may not even recognize, raising significant privacy concerns.
Data brokers do more than maintain databases of names and addresses; they create detailed profiles to help advertisers identify specific target audiences. The Federal Trade Commission (FTC) has documented this practice, noting that brokers combine data from various sources to infer sensitive characteristics, including income, political views, and health conditions.
One prominent data company, Acxiom, developed a segmentation system known as PersonicX, which categorizes households into lifestyle groups. For instance, one category, “Rural Everlasting,” describes older adults with lower income and educational attainment. Other categories include “Urban Scramble” and “Mobile Mixers.” These classifications are based on data-driven insights rather than personal descriptions provided by the individuals themselves.
Furthermore, the FTC has highlighted how companies use location data to create even more targeted advertising audiences. For example, InMarket developed audience segments like “Christian church goers” and “parents of preschoolers.” However, these labels do not necessarily reflect an individual’s actual beliefs or circumstances, illustrating the potential for misrepresentation.
Oracle’s BlueKai advertising business is another example of how data brokers have evolved to leverage extensive consumer data for targeted advertising. Although Oracle shut down its advertising products in September 2024, its history underscores the sophistication of the data broker industry. Importantly, a label does not need to be accurate to influence how a company perceives an individual.

Data brokers have also been known to categorize individuals based on estimated income, spending behavior, and financial circumstances. For instance, some classifications may label individuals as affluent or price-sensitive. A particularly alarming case involved Epsilon Data Management, which used advanced modeling to identify consumers likely to respond to solicitations. The company sold information about over 30 million Americans to operators of fraudulent schemes, leading to a $150 million settlement with the Justice Department.
In addition to financial profiling, data brokers have inferred individuals’ religious interests and political leanings based on various data points, including location patterns and purchase histories. For example, the FTC documented the existence of a “Christian church goers” advertising segment, which could misrepresent individuals who attend church for reasons other than religious affiliation.
Data brokers also create segments that reflect personal life stages, such as parents with young children or empty nesters. These classifications can help businesses target specific products or services but may also expose individuals to marketing that exploits their vulnerabilities. For instance, someone nearing retirement may receive different financial offers than a young parent, and incorrect assumptions can lead to inappropriate marketing strategies.
Individuals may not realize that their online activities—such as searching for medical information—can lead to inaccurate profiling. For example, researching diabetes for a family member does not imply that the individual has the condition, yet data brokers may use such searches to categorize them inaccurately.
The risks associated with data brokers extend beyond marketing. Basic personal information can aid scammers in crafting convincing approaches. For instance, a scammer with access to an individual’s name, address, and inferred life circumstances could create a fraudulent offer that appears legitimate. The Justice Department’s case against Epsilon Data Management illustrates how targeted consumer information can fall into the hands of criminals, enabling them to identify potential victims.
In 2025, the FBI reported that Americans aged 60 and older lost approximately $7.7 billion to internet crime, a significant increase from $4.9 billion in 2024. While not all of these losses were directly linked to data brokers, the sale of targeted consumer lists highlights how personal information can facilitate scams.
Finding every profile associated with one’s name can be challenging, as there is no centralized system for reviewing marketing predictions generated by companies. However, some state privacy laws grant residents the right to access, correct, or delete personal information, including certain inferences. California’s Consumer Privacy Act is a notable example, allowing eligible residents to request information held by businesses and to submit deletion requests through the state’s Delete Request and Opt-out Platform.
While it may not be possible to eliminate every prediction about oneself, individuals can take practical steps to reduce the amount of personal information available to data brokers. Reducing publicly accessible information can make it more difficult for unfamiliar businesses and scammers to create detailed profiles.
In conclusion, the implications of data brokers collecting and analyzing personal information are profound. The predictions they make can lead to misrepresentations that affect individuals’ lives in significant ways. As awareness of these practices grows, individuals are encouraged to take proactive measures to protect their privacy and understand the profiles being constructed around them.
