latestOpenAPI 3.1.02026-08-075421692.0 MBGet YouTube demographics
Returns audience demographic insights for a YouTube channel, broken down by age, gender, and/or country. Pass videoId to get the audience profile of a single video instead of the whole channel. Age and gender values are viewer percentages (0-100). Country values are view counts. Data is based on signed-in viewers only, with a 2-3 day delay. YouTube suppresses demographics for videos with too few signed-in views, so low-traffic videos can return empty breakdowns. Requires the Analytics add-on.
Query parameters
The Zernio SocialAccount ID for the YouTube account
YouTube video ID. When provided, demographics are scoped to this single video (must belong to the connected channel; otherwise 404 video_not_found).
Comma-separated list of demographic dimensions: age, gender, country. Defaults to all three if omitted.
Start date in YYYY-MM-DD format. Defaults to 90 days ago, or to the video's publish date (lifetime) when videoId is provided.
End date (YYYY-MM-DD). Defaults to 3 days ago, the newest fully finalized day (YouTube finalizes analytics with a ~3-day delay). An explicit endDate is honored up to today: days inside the delay window are provisional and may still be revised by YouTube (see provisionalSince in the response).
