Friendship is critical for individuals' well-being, but recent efforts to characterize Americans' friendship have suggested that these relationships are in peril. The present study is a report on the methods and results of three surveys from the American Friendship Project (AFP). The goal of the AFP is to be the most accurate and most complete account of American friendship as well as its health and change over time. The AFP reports on five critical facets of social health as it relates to friendship: 1) the structural factors of friendship (e.g., who are they, how many); 2) friendship quality (e.g., satisfaction, closeness); 3) social support from friends; 4) the quantity of online and offline communication; and 5) well-being (e.g., life satisfaction, loneliness, connection). Data was collected from two national samples of American adults in 2022 and 2023 and from a large sample of college students across three universities in 2022. The key finding from this investigation is, compared to the discouraging results of other recent surveys, Americans reported having more friends and fewer were friendless. AFP results also suggest that face-to-face (FtF) meetings among friends are quite common, as are telephone calls and text messaging. College student and adult samples reported very similar attitudes and experiences with friendship overall, but students were more likely to meet friends at school and to keep them for a shorter length of time. Another key finding is Americans long for greater closeness with friends; though over 75% were satisfied with the number of friends they had, over 40% felt they were not as close to their friends as they would like. Overall, the AFP is a rich source of data that can be used to answer a multitude of questions about friendship and its connection to well-being.
