on 15 February. The four have a combined population of about 100,000, with the 1st, 2nd, 4th, and 3rd arrondissements in that order being the four smallest in Paris. The matter was taken up in the National Assembly in August 2016, and approved in February 2017. In a postal referendum from 8 to 14 October 2018, the town hall of the 3rd arrondissement was chosen to house the new shared administration, and the name "Paris Centre" was chosen for the sector. The reform was implemented on 29 June 2020, the day after the second round of the 2020 Paris municipal election, with the four arrondissements now sharing a mayor and a district council. The four arrondissements continue to exist, but are no longer used as administrative and electoral sectors. See also Arrondissement, for other uses of the term.
