After initially dipping by 4% during the month following the release of iOS 14.5, the population size of income-based audiences in Facebook has bounced back to a similar level as mid-2021.

We highlight this finding in our Facebook Audience Size Report (July 2021), which helps advertisers understand how Facebook’s addressable audience size changes over time.

Reaching new highs

After Apple introduced App Tracking Transparency (ATT) in iOS 14.5 on April 26, 2021, the population size of income-based audiences initially declined by about 4% from May to June. But instead of continuing a downward trajectory, it shot back up by 4% from June to July. Now, it’s sitting near the highest level recorded in the past 12 months. 

Was Apple’s ATT responsible for the blip in June? We can’t say with any certainty. Based on the data, it appears that ATT hasn’t caused a steady decline that some advertisers had feared. And that indicates that Facebook may remain an effective mechanism for brands to target audiences based on income.

Why it matters

Audience-based advertising is a hot topic as marketers reinvent their targeting strategies for a privacy-forward world. With millions of iPhone users opting to “Ask App Not to Track,” since Apple rolled out its App Tracking Transparency (ATT) feature, some brands are witnessing a decline in the population size of remarketing audiences – with audience sizes sometimes even falling below the minimum required to serve ads. As a result, marketers are looking for alternative opportunities to invest budgets to reach their target audiences.

But there’s reason to believe Facebook’s built-in demographic and behavioral targeting segments may be more resilient in a privacy-forward world. Since they rely largely on Facebook’s rich internal data — such as interactions within the platform — Facebook’s built-in audience segments have a chance to remain an attractive way for brands to reach their target audiences.
