概要	The name generator is the standard survey technique for collecting egocentric (personal) network data. A respondent (ego) is prompted to name the people (alters) with whom they have a specified kind of relationship — those with whom they discuss important matters, exchange support, or socialize. A follow-up battery of name-interpreter questions then records each alter's attributes and the ties among the alters, yielding measures of network size, composition, density, and diversity for each respondent.	Homophily analysis quantifies the tendency of similar individuals to form ties — the principle that 'birds of a feather flock together'. It compares the rate at which people connect with others who share an attribute (race, gender, age, education, attitudes) against what would be expected by chance, distinguishing the homophily that arises merely from group sizes from the genuine, behavior-driven preference for similar others.
