The dependent variable – local rootedness – was revealed from network data (ties between local NGOs).We measured two possible kinds of relationships among NGOs: partnership and friendship. Notes, alongside the fields, clarified ‘partners’ as those with which an NGO has had at least one shared project over the last five years, and category of ‘friend’ supposed different types of contacts between organizations such as an exchange of information and/or the support of each other in small occasional events. In other words, NGOs keep contact with one another but do not have joint projects and/or a common budget.
