Data Brokers Advertising Data on Us Individuals

i surveyed ten major data brokers and found they were openly advertising data on us individuals sensitive demographic characteristics. These included race, ethnicity, gender, marital status, income level. I also found them advertising data on current and former members of the us Government and the us Military. And so what i catalogue in there is in detail the kinds of data the services they offer related to that data. It's a sprawling report. But it was meant as a survey of the space,. because i think there is not enough awareness ofwhat these data brokers might be doing secretly... but what they openly talk about selling in their marketing documents.
