Between 2020 and 2025, Montgomery, Collin, and Fort Bend counties saw significant population surges while carrying high FEMA natural disaster risk ratings. These findings highlight a trend of rapid expansion in areas that also face substantial environmental threats.
Why it matters
For homeowners in these fast-growing areas, balancing property appreciation with potential natural disaster exposure is an increasingly critical part of homeownership and long-term financial planning. Understanding these regional risks helps residents prioritize necessary property protections.
Montgomery County grew by 24.9 percent, while Collin County added 221,000 residents and reached nearly 1.3 million by 2025. Fort Bend County also saw a 17.4 percent increase during this period.
The players
FEMA
The federal agency responsible for evaluating natural disaster risk levels through its National Risk Index.
RealtyHomes
The real estate analysis firm that evaluated Census estimates alongside federal disaster data to rank these counties.
The details
RealtyHomes conducted this analysis by filtering U.S. counties with at least 100,000 residents against FEMA hazard data. Montgomery County, which added 68,800 housing units since 2020, ranked second nationally among high-risk growing areas. Collin and Fort Bend counties followed in the fifth and ninth spots, respectively, as Denton County also appeared in the top 11.

The Home Front
This data reflects a growing national trend where rapid residential development is occurring in regions with historically high vulnerability to environmental hazards. Such expansion puts more housing stock into high-risk zones, potentially influencing long-term property insurance and maintenance needs.
Check your specific property's natural disaster risk profile using official federal mapping tools to understand your exposure. Speak with a licensed insurance professional to confirm that your home insurance coverage is sufficient for your area's specific environmental hazards.
The takeaway
Growing populations in high-risk areas require proactive attention to property maintenance and hazard mitigation. Homeowners should regularly review their local emergency preparedness plans and confirm their property has adequate structural protections for the specific risks in their county.
