Methodology

How we know โ€” and how we don't bluff.

PriceWeather uses sourced, dated, and reproducible data. Every number in every report traces back to a specific public source, with a specific refresh cadence. No anonymous submissions. Anything we calculate ourselves is labeled as a PriceWeather estimate.

Our data principles

Every metric on every PriceWeather report is subject to four rules:

Where our data comes from

We use public and authoritative sources only. PriceWeather is not affiliated with, endorsed by, or partnered with any of the organizations listed below โ€” we cite their data with appropriate attribution.

Housing
Zillow Research + Redfin Data Center
Median sale price, list price, home value index, and rent at the metro, city, or ZIP level, wherever the source publishes it. We name the exact metric each time (for example, Redfin median sale price vs. Zillow median list price).
Source updates monthly
Insurance
State Department of Insurance filings
Rate filings and rate announcements from state insurance regulators and public insurers (for example, Florida OIR and Citizens). Reflects filed rates, not customer quotes.
Source updates as filed
Crime (official)
FBI Uniform Crime Reporting (UCR)
Reported incidents by category from the FBI Crime Data Explorer. Agency reporting is incomplete in some places, so we show the year and coverage.
Source updates annually
Climate & risk
NOAA + FEMA National Risk Index
Weather normals and natural hazard exposure.
Source updates annually
Daily costs
BLS Consumer Price Index + EIA energy prices
Price levels and changes for groceries, gas, utilities, and transportation, at the geography the source publishes (usually metro).
Source updates monthly
Schools
NCES + state Departments of Education
Per-pupil funding, student-teacher ratios, and enrollment at the district and state level; test scores from state report cards.
Source updates annually
Life expectancy & health
CDC + state vital statistics
Life expectancy at birth, mortality rates, hospital access, air quality tied to health outcomes.
Source updates annually
Jobs & salaries
BLS OEWS
Employment counts and median wages by occupation and metro.
Source updates annually
Air quality
EPA Air Quality Index
PM2.5, ozone, and other pollutants. Pollen and allergy rankings come from the Asthma and Allergy Foundation of America (AAFA).
Source updates daily; we cite annual summaries
Taxes
Census ACS + state and county tax offices
State income and sales tax rates, and county property tax rates and effective rates.
Source updates annually

How we're different from user-submitted comparison tools

Tools like Numbeo and Expatistan rely heavily on anonymous user submissions. That approach creates specific problems we structurally avoid:

Reliability

Their approach: anonymous user submissions can be manipulated by anyone with an agenda โ€” a landlord bumping their city's rent numbers, a chamber of commerce boosting a positive metric.

Our approach: sourced data only. Every number traces back to a named public dataset. Community signals (when we introduce them) are visibly labeled separately and never mixed with authoritative data.

Precision

Their approach: vague metric definitions like "meal at a good restaurant" mean different things to different users.

Our approach: every metric names exactly what it measures and the period it covers, so you know what you're comparing.

Freshness

Their approach: stale prices from years ago that no one has refreshed, with no visible timestamp on the metric.

Our approach: every number in a report shows its source and date. Out-of-date data is refreshed or left out before we publish.

Perception vs. reality

Their approach: the "crime index" is a survey of resident perception, not an actual crime count.

Our approach: we use official crime statistics and never blend resident-perception surveys into them. If we show both, they're labeled separately.

Local granularity

Their approach: metro-level averages hide material ZIP-level variance.

Our approach: we use the finest geography each source publishes (ZIP, city, county, or metro) and say which one. Metro averages can hide big local differences, and we flag that.

Verification and traceability

Every metric on a PriceWeather report can be traced back to its origin. If you ever see a number you'd like to verify:

Ask us to trace any number

Email hello@priceweather.com with the city, metric, and date you're checking. We'll reply within 5 business days with the specific source, the refresh cadence, and the calculation methodology behind that figure.

This isn't a marketing promise โ€” it's a commitment to reproducibility. If we can't trace it, we shouldn't have published it.

Important disclaimer: Forecasts and rankings on PriceWeather are informational estimates based on publicly available data. They are not financial, legal, tax, or investment advice.

Changes to this methodology

When we materially change how we source or calculate metrics โ€” for example, adding a new data provider, changing tier definitions, or updating refresh cadences โ€” we update this page with a new "last reviewed" date and log the change in our internal audit trail. Subscribers to the biweekly Price Weather Report receive an email notification for material changes.
