Sample Central provides profiles and demographic information on its members panel. As of January 2013, the panel had reached 4,500 registered members from across the UAE, representing all nationalities and ethnic groups. Members provide detailed demographic data and preferences when they register online. Individual profiles are managed through a personal web portal where members can update their interests and preferences. Statistical analysis of members shows distributions by age, location, marital status, income level, and other details. Category and product trials are also tracked to provide insights into members' preferences.
