Page views is right on but I noticed that the support documentation on stats adds more clarity.
Can I track other details?
WordPress.com stats do not track unique visitors, countries, IP addresses, or other details. http://en.support.wordpress.com/stats/#additional-info
A page view is a request to load a single page of an internet site that results from a page request from a web surfer clicking on a link on another HTML page which is pointing to the page in question.
A unique visitor is access from a single IP to a web server that generates page views and hits during a particular visit. When a visitor has cookies disabled, there is no way of establishing if they are a unique visitor or not.
