Hi,
I'm from the Google Ads API team. I hope you're doing great today.
If you're trying to generate "age range" reports, you may check out age_range_view (https://developers.google.com/google-ads/api/fields/v14/age_range_view) report, and see if this is what you're looking for. I suggest you utilize its query builder (https://developers.google.com/google-ads/api/fields/v14/age_range_view_query_builder) to determine the available fields and check if the query is valid.
Let us know if you have further clarifications.
