Facebook Essentially Has Been Telling Advertisers It Can Reach More People Than Actually Exist, Analyst Finds (marketwatch.com)

Facebook claims its ads have the potential to reach more people than recent U.S. census data shows exist, and that's troublesome for one analyst, who thinks third-party measurement services stand to benefit. From a report: Recently, Pivotal Research Group analyst Brian Wieser was intrigued by a trade publication study in Australia that said Facebook was claiming to reach 1.7 million more 16- to 39-year olds than actually existed in the country, according to Australian census data. In reproducing the study for the U.S., Wieser said Facebook's Ads Manager claims it can potentially reach 41 million 18- to 24-year-olds, 60 million 25- to 34-year-olds, and 61 million 35- to 49-year-olds. The problem arises when Wieser pulls up U.S. Census data from a year ago, showing 31 million 18- to 24-year-olds, 45 million 25- to 34-year-olds, and 61 million 35- to 49-year-olds. The upshot: Where is Facebook getting the extra 25 million 18- to 34-year-olds that the U.S. census did not count? "Conversations with agency executives on this topic indicate to us that the gap between Facebook and census figures is not widely known," Wieser said. "While Facebook's measurement issues won't necessarily deter advertisers from spending money with Facebook, they will help traditional TV sellers justify existing budget shares and could restrain Facebook's growth in video ad sales on the margins."

Advertising/marketing should be about 0.001% its current worth.

Fake Ages

[Luthair]

Do the authors of the article really not know that people use fake ages, have two accounts, etc.

Re:Who do you trust more - Facebook, or the govern

[DontBeAMoran]

Fake accounts, multiple accounts, fake information such as age/etc.

Not people... accounts

That's because you're reaching potential FB accounts, not people. There are many, many fake accounts on FB. I know of lots of people who have abandoned accounts and created new ones - either because they lost their password, or were being harassed, or because they just didn't know any better (my dad, who is not a big computer user, created a second account early on when he thought he was just logging in. It's still there, just not being used). As others have said, many people lie about their ages - at first FB would not allow minors to have accounts, so they would simply say they were at least 18. So that age range of demographics has to be quite skewed as well, especially the 18-25 range.
