Meta's EU reach by country, age and gender: what it is and how to read it
Published 13 Nov 2026. Data read Meta's EU reach read 2026-11-12 and 2026-11-13; breakdown check from Poseidon's nightly audit of 2026-11-13; tools' pages read 2026-11-12 and 2026-11-13. Source: Meta's Ad Library (EU transparency data), read by Poseidon, unless the text names another source.
For every ad shown in the EU, Meta's Ad Library publishes how many people in the EU saw it, and splits that audience by country, age and gender. The split is Meta's own data, not an estimate, but it doesn't add up exactly to the total, so the safe way to read a country or an age band is as a share of the split, never as a number of people.
What Meta shows on each ad
Open an ad in the Meta Ad Library, then "See ad details", then the European Union transparency section:
| Field | What it is |
|---|---|
| EU reach | People in the EU who saw the ad at least once since it started |
| By country | The same audience, row by row per EU country |
| By age and gender | Rows per age band (18–24 to 65+) and gender (women, men, unknown) |
| Targeting | The age range, gender and places the advertiser chose |
It's shown for ads delivered in the EU only, and it's the figure as of today: the Ad Library keeps no history.
Why the split doesn't add up to the total
Poseidon checked this on 6,664 readings of Meta's data (nightly audit, 13 November 2026). Adding up an ad's age and gender rows gives a figure that differs from Meta's EU total:
| Rows added up, divided by Meta's EU total | Measured |
|---|---|
| Lowest | 0.93 |
| Median | 1.006 |
| Highest | 1.10 |
| Readings where the rows add up to more than the total | 4,038 of 6,664 |
The rows are close to the total but not equal to it, and Meta doesn't publish why. In 2,493 readings, a single country's rows alone added up to more than the EU total. So Poseidon gives a country, an age band or a gender only as a share of Meta's split, and the only number of people it shows is Meta's EU total.
What the split looks like on winning ads
Across 6,547 winning e-commerce ads read on 12 and 13 November 2026, women made up 69.5% of Meta's split and the largest age band was 35 to 44 (25.9%). Each ad's main country, the one holding the largest part of its split, spreads like this:
| Main country | Winning ads |
|---|---|
| Germany | 1,233 |
| France | 1,184 |
| Italy | 880 |
| Poland | 824 |
| Spain | 768 |
| the Netherlands | 559 |
| 22 other country codes | 1,099 |

FAQ
Is this data an estimate?
No. It's Meta's own count, published under the EU Digital Services Act. What isn't published is spend and impressions. See can you estimate spend from reach?
Why doesn't the split add up to the total?
Meta doesn't say. Poseidon measured it: in 4,038 of 6,664 readings the rows added up to more than the total, by 10.4% at most. That's why a country is best read as a share.
Is it the targeting or the real audience?
The real audience: who Meta actually delivered the ad to. The targeting is listed separately, and the two often differ.
