(CNN/Money) Consumer data companies are selling lists of rape victims, seniors with dementia and even those suffering from HIV and AIDS to marketers, underscoring the need for tighter government regulations, a privacy group told Congress Wednesday.

The World Privacy Forum uncovered these lists, along with several others, while investigating how data brokers collect and sell consumer information. Marketers buy this data so they can target shoppers based on everything from their income to clothing size.

Other lists the nonprofit found included the home addresses of police officers, a mailing list for domestic violence shelters (which are typically kept secret by law) and a list of people with addictive behaviors towards drug and alcohol.
