您管理着一家泳池安装公司，并在自己的网站上发布了一个有关如何正确保养泳池的新操作视频。Google Analytics 提供了大量有关用户与该视频互动情况的数据。下面哪一项属于 Google Analytics 所收集的“用户属性”？

User properties describe segments of your user base, such as their demographic information or device preferences. Language preference is a characteristic of the user, making it a user property. The number of users watching the video and the number of users opening the page are metrics, which are quantitative measurements of user behavior. The video's title is an event parameter or content dimension, describing the content itself, not a characteristic of the user.
