Revises how demographic data for small‑business loan applications are collected and reported under the Equal Credit Opportunity Act. Lenders must give applicants clear notice that the Bureau requires the data, that answering is voluntary and won’t affect credit decisions, and that applicants are not required to provide the information. The bill also limits how institutions may obtain demographic data, requires a Bureau rulemaking before collected data can be deleted or materially changed, creates a temporary enforcement safe harbor while institutions adjust, and adds statutory definitions for "financial institution" and "small business."
