This data combination tool allows you to combine some variables gathered in the survey to explore their relationships. Each dot represents one city. The size of each dot can be changed according to different items, namely: the city’s revenue as a % of its   total expenditure; the share of the informal economy as a percentage of the city’s GDP; the number of policy sectors for which the city has the executive power; the number of instruments available to citizens to influence local policies; the city’s electoral turnout during the most recent elections. The colour of each dot can be changed according to: the city’s population; the city’s location (world region); the city’s wealth level.
