导出的受众群体始终按用户 ID 和设备 ID 来识别用户。这意味着，与观众群体导出结果相比，有关观众群体的报告可能会显示更多用户。例如，如果“在报告中使用的 ID”为“基于设备”，则报告不会根据 User-ID 删除重复数据，但导出的受众群体会。
回填一致性
当您在 Google Analytics 中创建受众群体并开启 Google Ads 再营销后，Google Analytics 会在 Google Ads 中利用最近添加的成员回填该受众群体。不过，Google Analytics 报告和导出的受众群体不会包含回填的受众群体成员。在为 Google Analytics 报告和受众群体导出创建受众群体后，用户必须记录一个事件，才能在该受众群体中显示。

Exports are static snapshots, updated daily during daylight hours. Data expires after 72 hours, requiring daily new exports for the latest user list. User limits apply, providing samples in large audiences. Exports identify users by User ID then Device ID, differing from reporting identity settings. Backfilled memberships aren't included. User counts may differ between the UI and exports.\n"],null,["# Audience export data expectations\n\nThis guide explains important information about the data you see in audience\nexports.\n\nData freshness\n--------------\n\nAudience export data freshness is how long it takes Google Analytics\nto collect events, process events, and then update user membership\nin your audiences. For example, if that process takes 24 hours, then the\naudience export data freshness is 24 hours. For more information, see\n[Data Freshness](//support.google.com/analytics/answer/11198161).\n\nAudience export data freshness averages 24 hours. You might not see users\nin audience exports for events that took place less than 24 hours ago. For\nexample, if a user completes their first purchase, and then 7 hours\nlater you create an audience export for the \"Purchasers\" audience,\nyou likely won't see the user in that audience export. After 14 to 38 hours,\nit's likely you will see the user in new audience exports.\n| **Note:** We recommend only requesting an audience export once per day, per audience.\n\nAudience membership data is updated once per day, typically during\ndaylight hours in the property's timezone. This means that\naudience exports for the same audience at 9 AM and 11 AM will likely\nreturn the same data, but a new audience export later that day might include\nnew data, if your membership data is updated in the afternoon.\n\nAudience exports are snapshots\n------------------------------\n\nAudience exports are lists of users in an audience at a specific point in\ntime. When you create an audience export with the Data API, that audience export\nrepresents a snapshot of the users in that audience about 24 hours before you\nmade that request. Audience exports from the Data API are static, so you must\ncreate a new audience export to see the most recent data for that audience.\n\nIn contrast, for [Google Ads remarketing](//support.google.com/analytics/answer/9313634),\nGoogle Analytics automatically and continuously exports users in\naudiences to Google Ads, so you don't need to manually request new audience\ndata.\n\nData expiration\n---------------\n\nAudience exports expire after 72 hours. New users might enter and exit an\naudience each day. To view the latest users in an audience, you need to\ncreate new audience exports each day.\n\nUser limits\n-----------\n\nWhen the size of an audience or property exceeds a user limit,\naudience exports return representative samples of the audience.\n\nThese limits depend on your property type, for example a standard or\n360 property, and are enforced in each audience export request.\n\nReturned users are users in the requested audience, and considered\nusers are users that may or may not be a member of the audience.\n\n| Limit Type | Standard Property Limits | Analytics 360 Property Limits |\n|----------------------|--------------------------|-------------------------------|\n| Max returned users | 2 million | 200 million |\n| Max considered users | 10 million | 1 billion |\n\nReporting identity consistency\n------------------------------\n\n[Reporting identity](//support.google.com/analytics/answer/10976610)\ndecides how users are deduplicated in reports.\n| **Important:** Audience exports don't change based on the reporting identity setting.\n\nAudience exports always identify users by\n[user ID](//support.google.com/analytics/answer/9355972), then device ID.\nThis means\nthat reports on an audience can show more users than the\naudience export returns. For example, if the reporting identity is\n\"Device based\", then reports don't deduplicate based on user ID,\nbut audience exports do.\n\nBackfill consistency\n--------------------\n\nWhen you create an audience in Google Analytics and turn on Google Ads\nremarketing, Google Analytics\n[backfills that audience in Google Ads](//support.google.com/analytics/answer/9313634)\nwith recently added members. However, Google Analytics reports and\naudience exports don't contain backfilled audience memberships.\nA user must log an event after the audience is created for Google Analytics\nreports and audience exports to show the user in that audience.\n\nFor example, if a user logs a purchase event on June 20th, and you\ncreate a \"Purchasers\" audience on June 21st, then you likely need to\nwait until June 22nd to see that user in new audience exports. However, that\nuser will only be in the audience export if the user has logged any event on\nJune 21st.\n\nUser count reporting\n--------------------\n\nThe total user count displayed in the [Audience report](https://support.google.com/analytics/answer/12931462)\nand the [Audiences](https://analytics.google.com/analytics/web/#/?pagename=admin-audiences&utm_source=gahc&utm_medium=dlinks)\nmanagement page in the Google Analytics UI may differ from the number of users\nin an audience export.\n\nThe *total users* metric in the Google Analytics UI reports shows historical\naudience memberships at the time of the event, whereas an audience export\ncontains only memberships that haven't expired due to the audience membership\nduration setting.\n\nFor example, if the audience membership duration setting is 30 days, and you\nreport on audience total users in the Google Analytics UI over the last year,\nyou might observe 12 times more users in the Google Analytics UI versus in the\naudience export *(12 = 365/30)*."]]
