Hi,
Thank you for your questions.
The campaign report aggregates all the metrics (ex. impressions) accumulated at the campaign level. Meaning, this report should contain as well the metrics from all other criteria (if
other types are also being targeted) that triggered the ads under the said campaign.
On the other hand, the age_range_view will only return statistics aggregated at the age range criterion. I hope this helps.
Best regards,
