The people would be chosen using stratified random selection from everyone on the electoral roll. The process would be done in a few steps. First, a large number of randomly chosen citizens (around 5000) would be asked if they are interested in participating: it would not be compulsory, and would not be paid, although all expenses would be covered, including childcare if needed. From those who express an interest, a stratified random selection is made to ensure that the final parliament is gender balanced with a proportional number of people across all age groups and education levels, matching the latest census data.
This representative sample of people would form the citizens' parliament.
