Housing & affordability
How it’s calculated — housing affordability →Prices for everything a household buys run about 2% below the national average — the Bureau of Economic Analysis index reads 98.3, against 100 for the nation. Nationally, housing drives most of the spread between places in this index; other goods vary far less.
The Federal Housing Finance Agency’s house price index for the Austin-Round Rock-San Marcos, TX Metro Area is up 15% over five years, and up 0.3% over the last year. It follows repeat sales of the same homes, so it measures price change rather than which homes happened to sell.
Homeowners here who pay a tax bill pay a median of $7,205 a year in real estate taxes, about 1.61% of the median home value.
HUD’s Fair Market Rent for a two-bedroom, set near the 40th percentile of recent new leases, is $1,852, close to the $1,796 tenants already here pay.
At HUD’s Fair Market Rent of $1,852 a month for a two-bedroom, keeping rent to 30% of income takes a household income of about $74,100 a year, about 67% of the median household income here of $111,340.
The typical renter household here spends 29% of its income on rent, below the 30% threshold at which a household is considered cost-burdened. Median gross rent runs $1,796 a month.
A median home at $447,000 costs 3.3 times the median income of its owner-occupied households, $136,273, above the historic benchmark of about 3 times income.
Prices here run about 2% below the national average. The spread between places is driven mostly by housing — goods vary far less — and this excludes taxes.
Published for the Austin-Round Rock-San Marcos, TX Metro Area as a whole. Prices are regional — people shop, commute and rent across a metropolitan area rather than within a city boundary — so this describes the cost of living around this place better than a figure drawn to its own limits would.

Growth & development
How it’s calculated — growth →Development Momentum
An AreaProfile calculation combining permit volume per resident, its direction over one and three years, population change and employment growth. Permit volume alone is not the measure.
Population has grown 18% since 2020, reaching 727,480 in 2024.
Permit activity fell in each of the 4 calendar years through 2025.
Population is still rising but the pace is easing: 727,480 residents in 2024, up 3.7% over the year, a smaller gain than the year before.
New construction is predominantly single-family: of 4,338 units permitted over the past twelve months, only 9% are in buildings of five or more homes.
Federal tax returns show Williamson County gained about 2.6% of its residents through moves within the US in the most recent year, counting those who arrived against those who left. Households that moved in reported an average income of $97,300, above the $87,027 of households that moved out.
At 6.4 permitted units per 1,000 residents, building activity is above the median for measured US counties.

Physical risk
The hazards accounting for most of this area's expected annual loss are inland flooding, cold wave and tornado, with inland flooding alone responsible for 52% of it. Every one of these is independently rated low or minimal nationally — this describes how a small risk is composed, not a large one.
Overall hazard risk is lower than 90% of measured US counties.
Low or minimal exposure: winter weather, cold wave, tornado, inland flooding, heat wave, lightning, ice storm, hurricane, strong wind, earthquake, landslide, tsunami, volcanic activity, avalanche, coastal flooding.
Hazard ratings are AreaProfile calculations derived from the FEMA National Risk Index v1.20.0 (December 2025). These are FEMA’s own figures for this county rather than a value derived from surrounding geographies. FEMA does not endorse this presentation. Higher physical resilience means lower exposure.
These are deaths, not offenses — they say nothing about burglary, theft or assault.
Williamson County records 3.7 homicide deaths per 100,000 residents a year, near the middle of counties measured. The CDC does not publish this below county level.
Firearm deaths of all intents run at 12.3 per 100,000 — more than the homicide rate, since the figure counts suicides and accidents as well as homicides.
Drug overdose deaths run at 9.5 per 100,000 residents in Williamson County.
Firearm deaths count every intent together, and nationally the majority are suicides rather than homicides, so the firearm figure and the homicide figure above it count some of the same deaths twice over. They overlap and should not be added together.
Death rates are crude rates — deaths divided by population, not adjusted for age — except where a count was too small for the CDC to publish and it modeled the rate, which the card marks. They come from provisional death certificate records, published by the CDC by county and not below it. So they describe Williamson County as a whole. They are shown and not scored. How to read death rates.
What this profile does not cover
Each of these is absent for a reason, not by oversight. The Area Score is calculated without them; the weighting is on the methodology page.
- Reported crime
- Offenses reported to police are published by department rather than by town, so AreaProfile shows a rate only on city profiles, and only where that city’s department submitted every month of a year. City profiles inside this area carry their own figure where their department reported a full year. A partial year is never scaled up to look complete, and arrest counts or news volume are never substituted for it.
- Air quality
- The EPA publishes an air-quality index only where a monitor sits. There is none in this county, and a modeled value would be a different kind of number from the measured ones everywhere else on this page.
- Taxes
- Income and sales taxes are not published: no source covers them nationally with a method open enough to check. Property taxes are shown in the housing section but are not part of the score. The cost-of-living index above is a price level for all consumption, not a household budget, and it excludes taxes. Nothing here is individualized tax advice.
- Anything about a specific address
- Every figure describes an area, not a street or a house.
