The population census is a fundamental tool for gaining a better understanding of the demographic and residential characteristics of a territory.
In the Principality of Monaco, this statistical mission dates back to 1757 and has been regularly modernised since then. An important milestone was reached in 2023, with the adoption of a new census method based on administrative sources, known as “register-based,” in place of traditional field surveys.
This methodological change, validated by the Scientific Council for Statistics and Economic Studies, the Government and the Prince’s Palace, marks a major step forward: it now makes it possible to update demographic data on the resident population annually, improving availability and reducing operating costs.
