Online Access Panels are groups of internet users who have agreed to take part in online market research surveys. Upon registration, the panel members provide contact information and socio demographics about themselves and about the household they live in. Having this information pre-identified, it allows making national representative sample selections for conducting online surveys. Online Access Panels provide a quick, cost-effective way of contacting samples for many types of research.IAP owns one of the largest Online Access Panels in the world with more than 4 million panel members worldwide (Europe, the Americas and Asia Pacific).

A panelist that is eligible for being invited to surveys. For IAP, "Active" means that we consider the panelist as being engaged in our panel and likely to respond to survey invitations. Inactive panelists are removed from the panel database thanks to regular automatic purges. Panelists can be inactivated for many reasons: if they don't respond, if they unsubscribe, provide incomplete or invalid information, if their information is the same as an existing panelist (duplication), if they are temporary on vacation, if they have had a fraudulent response behavior in the past surveys, etc. At Ipsos, active panelists are more important than many panelists, unlike some other companies who promote large/mega databases, in which many of the panelists are actually inactive and are not reachable when needed (for research purposes).

Asynchronous JavaScript and Xml – Group of inter-related web techniques used for creating interactive web applications.

Ampario is the Ipsos brand name for a type of sample, untargeted or non-traditional sample sources.

Percentage of people who leave the panel for personal or panel decision reasons (e.g., quality /panel activity). The Access Panel is continuously renewed. New members are joining, and existing ones are leaving. This "panel health" indicator is monitored by the Panel team and is mainly associated with the panel recruitment rate (new and fresh panelists).
