The Social Fabric of College: Economic Connectedness by Institutional Tier

Economic connectedness measures cross-class friendships. Exposure measures mixing. Bias measures whether friendships form. Hover for details.

Key insight: Elite schools score highest on EC and exposure, but friending bias is near-zero everywhere. The gap is driven by who’s on campus (exposure), not by whether students befriend across class lines.
