Facebook and its advertisers want to know everything about you, online and off. The latest push is around knowing where you grew up. If you’ve signed onto Facebook lately, you’ve probably seen it.
They’ve been asking for your hometown on your profile page for several weeks now, but they’ve gotten more aggressive lately: they’re putting it at the top of people’s news feeds and saying that your profile isn’t complete without it.
Why is Facebook pestering you to know where you grew up? It’s personal information that fills in another piece of the puzzle that makes you you. Knowing your hometown makes it easier to target you, not someone with a similar name. Knowing where you grew up–and where you live now–gives Facebook and its advertisers are better sense of the stores you like, where your family and friends are located, where you’re most likely to travel, and more. Your real life and history translates to more advertising money to Facebook, a revenue source that made up 83% of Facebook’s income in 2012.

Facebook’s recent push to get your hometown is showing up at the top of users’ news feeds.
Facebook recently extended its advertiser tracking capabilities into the real world through partnerships with big data brokers like Acxiom and Datalogix. This data sharing will let advertisers know if people who see their ads online–on Facebook–go buy whatever was advertised in real life. They piece together your offline and online activities through your personal information. Let’s say you buy a shirt at the mall and give the person at checkout your email (they’re always asking for it). If that’s the same email you use on your Facebook account, advertisers can link the two. They also link your online and offline lives through your phone number or zip code.
