Transparency and participation are themes that have become indispensable in politics. The government is increasingly using citizen participation to create support for its plans. They do this by organizing citizen consultations. This is an event where citizens come together to discuss government plans. All voices in society should be represented; rich and poor, young and old, rural and urban. This information is of course not readily available, so our challenge was to collect it in a privacy-friendly manner. Together with EMMA, a research, consultancy and participation agency, we have developed a tool with which a representative group can be composed.
