CensusVision and HMDAVision answer different but complementary questions. CensusVision is built on survey-based, self-reported Census microdata and is designed to understand communities, affordability, population characteristics, and housing demand—what exists before a mortgage application. HMDAVision is built on loan-level HMDA transaction data reported by lenders under Regulation C, with strict reporting standards and regulatory guardrails, and focuses on actual mortgage applications, originations, pricing, and outcomes. Together, they allow users to connect housing demand and community context with observed mortgage credit outcomes.
