Facebook currently provides a staggering 29,000 individual categories to its advertisers.
These allow advertisers to drill-down and target specific groups amongst the 1.79 billion monthly active users.
Of those 29,000 categories, Facebook says 600 come from third-party data providers.
According to the research conducted by ProPublica, the majority of this data from commercial data brokers is financial.
It allows advertisers to single-out Facebook users in categories including, "total liquid investible assets $1 - $24,999", "people in households that have an estimated household income of between $100K and $125K", or even "individuals that are frequent transactor at lower cost department or dollar stores".
Regardless of whether you've ever posted a status, photo or liked a brand on your social media feed relating to your preference for lower cost department stores – Facebook knows.
