• Women are 2× more likely than men to discuss emotional difficulties with a close friend in the past month.
• Women's friendship networks function as a primary mental-health infrastructure.

Men

• The share of men with zero close friends rose from 3% in 1990 to 15% in 2021 — a five-fold increase.
