In January 2012, thirteen new towns have made their entry into the agglomération.^[4] In 2013, five new towns entered the agglomération: Gargenville, Guernes, Fontenay-Mauvoisin, Fontenay-Saint-Père and Saint-Martin-la-Garenne, bringing the number of communes of CAMY to 35.^[5] Note that the second city of the metropolitan area, Limay, 16 005 inhabitants, which is also the most industrialized and do not want to join the CAMY. It should, according to the SDCI Yvelines, join Issou and Guitrancourt, common on the right bank of the Seine, to form a new intercommunalité.^[6]
