A recent study from Redfin real estate revealed that Miami-Dade County lost approximately 67,000 residents from 2023 to 2024.
Two of the leading factors cited for relocation were costs and flooding from hurricanes and major thunderstorms.
Several factors are cited by Redfin and local agents as contributing to the exodus:
- Flood and climate risk: Miami-Dade is classified among the top 10% of U.S. counties in terms of flood-risk for homes — about 36.3 % of homes face high flood risk.
- Rising insurance costs and homeowner burden: One Miami real-estate agent cited that his homeowners insurance rose from under $2,000 two years ago to $6,700 per year, while flood-insurance premiums climbed from about $400 to $1,250.
- High cost of living and housing: Miami’s pandemic-era growth and popularity have driven up housing and maintenance costs, making the city less affordable for many residents. Fast
- Pandemic-era migration correction: Some of the residents moving out may have relocated during the pandemic boom and are now returning to their prior states or reconsidering cost/quality-of-life trade-offs.
While Miami-Dade’s domestic outflow is steep, the county’s overall population still grew by about 2.3 % in 2024, driven by international migration (estimated net international inflow of 123,835). The outflow trend represents a sharp acceleration: Miami-Dade’s net outflow widened from –50,637 in 2023 to –67,418 in 2024.
For urban planners and policymakers in Miami, the trend suggests vulnerabilities in the city’s appeal as a migration destination—especially as climate risk, affordability and insurance cost burdens escalate.
For real-estate markets, the outflow may signal a cooling of demand from out-of-state buyers or a shifting preference toward less cost- or risk-exposed locations.
