Dollar for dollar

Reading	Maricopa CountyArizona	Salt Lake CountyUtah
Home valueMedian value of owner-occupied homes.	$452,800	$525,700
Price ratioMedian home value divided by median household income. How many years of full income equals the home price. Lower is more affordable.	5.1x income$452,800	5.4x income$525,700
RentMedian monthly rent for a whole rented home — any size, studio through 5+ bedrooms mixed together — not per bedroom. "Gross" means utilities are included on top of contract rent. Half the county's rentals cost less than this, half more.	$1,708/mo	$1,592/mo
Childcare costChildcare for two children as a share of the county's median household income. A burden percentage, not a dollar price.	27.5% of income	21.3% of income
ElectricityRoughly what this county's middle household pays for electricity each month, counting only homes that pay an electricity bill. The Census reports this as a $50-wide bracket; the ~ figure is that bracket's midpoint, so the real median sits within about $25 of it. Bills vary widely with home size, climate and thermostat habits — this is what residents actually pay, not a quote for your home.	~$175	~$75
GasRoughly what this county's middle gas-billed household pays each month. The Census reports this as a bracket; the ~ figure is that bracket's midpoint. Homes with no gas service at all are not counted, and in many counties that is most homes — an all-electric home would pay nothing here regardless.	~$37	~$62
Water & sewer (yearly)Roughly what this county's middle billed household pays for water and sewer per YEAR — unlike the monthly electricity and gas figures beside it. The Census reports this as a bracket; the ~ figure is that bracket's midpoint. Homes on private wells or with water bundled into rent are not counted.	~$625	~$625
Household incomeMedian annual income of a whole household, all earners combined. Not one person's salary.	$89,300	$97,494

Electricity and gas brackets are monthly; water & sewer is yearly. Household income is context, not a cost. There is no total row because these measures mix dollars, ratios and brackets, and a sum of them would be an invented number.

Cost of Living

Reading	Maricopa County	Salt Lake County
Median Home ValueMedian value of owner-occupied homes.	$452,800	$525,700
Home Price-to-Income RatioMedian home value divided by median household income. How many years of full income equals the home price. Lower is more affordable.	5.1x income$452,800	5.4x income$525,700
Rent BurdenAnnual whole-home rent (median gross rent × 12, any bedroom count) as a share of median household income. Below 30% is considered affordable; above 30% is cost-burdened.	23.0% of income$1,708	19.6% of income$1,592
Median Gross RentMedian monthly rent for a whole rented home — any size, studio through 5+ bedrooms mixed together — not per bedroom. "Gross" means utilities are included on top of contract rent. Half the county's rentals cost less than this, half more.	$1,708	$1,592
Property Tax Bill (Current Owners, Yearly)Median yearly property tax paid by the county's current homeowners. Long-held homes are often taxed on an old assessed value, so a new buyer usually pays more than this, and much more where the assessment resets at sale (California, Florida, Texas and seven more; each county's page says which rule applies). Withheld where the Census caps the figure at $10,000+ or its margin of error is wide.	$1,983	$2,836
Property Tax Rate (Current Owners)Median yearly property tax paid divided by median home value, for the county's current owners. Not the rate a buyer signs up for: assessment caps and homestead exemptions pull this below a new purchase everywhere, and far below it where value resets at sale.	0.44%	0.54%
Child Care Cost BurdenChildcare for two children as a share of the county's median household income. A burden percentage, not a dollar price.	27.5% of income	21.3% of income
Electricity Bill (Middle Household)Roughly what this county's middle household pays for electricity each month, counting only homes that pay an electricity bill.

Health & Healthcare

Reading	Maricopa County	Salt Lake County
Life ExpectancyEstimated average life expectancy at birth. Where CHR's own confidence interval spans more than a decade — which happens in counties with few recorded deaths — the estimate is treated as missing and a modeled figure is shown instead, marked as such. Shown for context only: it does not feed the fit score.	77.5 yrs	78.6 yrs
Poor or Fair HealthPercentage of adults who report poor or fair general health. This single measure reflects the combined effect of underlying factors like smoking rates, obesity, physical inactivity, and child poverty.	17.1%	15.6%
Uninsured RatePercentage of the population without health insurance coverage.	12.5%	10.4%
Health IndexComposite 0–100 score of five CHR health outcomes (higher is healthier), shown only where at least three are published. Shown for context only — its inputs already score individually, so counting it too would weight them twice.	67/100	75/100
Injury DeathsDeaths from all injuries — accidents and violence combined — per 100,000 people, averaged over five years. Measured mortality, not reported crime; it replaced an earlier score that was modeled from income and education rather than measured.	92 per 100k	75 per 100k
Premature Death RateYears of potential life lost before age 75 per 100,000 population. Lower is better.	8,525 per 100k	6,733 per 100k
Adult Obesity RatePercentage of adults with a body mass index of 30 or higher.	32.7%	32.8%
Adult Smoking RatePercentage of adults who currently smoke cigarettes.	11.8%	8.5%

Broadband AccessPercentage of households with a broadband internet connection.	92.1%	93.6%
Child Care CentersLicensed childcare centers per 1,000 children under five — availability, as distinct from the cost burden.	5.4 per 1,000 children	5.8 per 1,000 children

Environment & Disaster Risk

Reading	Maricopa County	Salt Lake County
Natural Hazard RiskWhere this county's expected annual dollar loss to natural hazards ranks among all US counties (18 hazard types; frequency × exposed people and property × social vulnerability). It ranks dollars at stake, not how often disasters happen — a big city under rare hazards can outrank a rural county under frequent ones, simply because more is exposed.	100th pctile	99th pctile
Wildfire RiskPercentile of expected annual dollar loss to wildfire among all US counties — event frequency times the people and property in the burnable area. High-value counties rank high even when fires are infrequent.	100th pctile	98th pctile
Hurricane RiskPercentile of expected annual dollar loss to hurricanes among all US counties. Inland counties FEMA marks not-applicable show no value rather than a zero score, so about a quarter of counties carry no figure here.	27th pctile	—
Tornado RiskPercentile of expected annual dollar loss to tornadoes among all US counties — frequency times exposed people and property. A dense county where tornadoes are genuinely rare can still rank in the 70s because one rare strike over a city costs more than frequent strikes over empty plains; this is a dollars-at-stake ranking, not a how-often ranking.	84th pctile	71st pctile
Earthquake RiskPercentile of expected annual dollar loss to earthquakes among all US counties. Rare-but-severe fault-line exposure dominates: a county can go decades quiet and still rank near the top because the eventual event is priced in.	97th pctile	100th pctile
Flood RiskPercentile of expected annual dollar loss to flooding among all US counties (the higher of coastal or riverine).	100th pctile	93rd pctile
Good Air Quality DaysPercentage of monitored days with AQI in the 'Good' category (0–50). Higher is better.	11.0%	41.0%
Median Air Quality IndexMedian annual AQI. Below 50 is Good; 51–100 is Moderate; above 100 is unhealthy.	AQI 72	AQI 54

Schools & Education

Reading	Maricopa County	Salt Lake County
High School Graduation Rate4-year adjusted cohort graduation rate for public high schools.	89.5%	91.7%
Bachelor's Degree or HigherShare of adults 25+ with a bachelor's degree or higher. Withheld where the margin of error is as large as the figure itself.	36.7%	39.4%
Graduate Degree RateShare of adults 25+ with a graduate or professional degree.	14.0%	14.6%
College Enrollment RateShare of the county's 18–24 year-olds currently enrolled in college or graduate school — reflects whether a campus sits in the county, not the educational attainment of the county overall. Withheld where the margin of error exceeds 20 points or a zero carries any margin.	35.6%	35.9%
3rd-Grade Reading ScoresAverage grade-level performance of 3rd graders on reading tests, aggregated from school districts. 3.0 means performing at grade level; higher means ahead of it.	3.0 grade level	3.1 grade level
3rd-Grade Math ScoresAverage grade-level performance of 3rd graders on math tests, aggregated from school districts. 3.0 means performing at grade level; higher means ahead of it.	3.0 grade level	3.1 grade level
K-12 Education IndexComposite 0–100 score of two K-12 indicators, graduation rate and child poverty, shown only where both are published. Shown for context only; the graduation rate it is built from already scores on its own.	80/100	85/100
Higher Education IndexComposite 0–100 score of higher education attainment and access (higher is better), shown only where at least two of its three inputs are published. Shown for context only — degree attainment and college enrollment already score individually.	51/100	54/100

Community Size
