Ecovillages are intened to be socially, economically and ecologically sustainable intentional communities. Most aim for a population of 50-150 individuals because this size is considered to be the maximum social network according to findings from sociology and anthropology Larger ecovillages of up to 2,000 individuals may, however, exist as networks of smaller "Eco-municipalities" or subcommunities to create an ecovillage model that allows for social networks within a broader foundation of support.
