Editorial Standards

Our Editorial Mission

CostByCounty is a data-journalism site. Our job is to take the housing-cost statistics that the federal government already publishes — median rent, home values, owner costs, and affordability ratios — and present them in a form that someone planning a move, comparing places to live, or researching housing trends can actually use. We are not a financial-advisory resource. We do not provide investment advice, mortgage recommendations, or relocation consulting.

Every page on this site is grounded in a primary-source dataset from a U.S. government agency. Where we compute composite scores or rank counties, we publish the underlying formula on our methodology page. Where we draw on AI assistance for prose, we say so on this page and on the page itself.

ByCounty Editorial Team

The ByCounty Editorial Team is the shared publishing function responsible for maintaining the network's source standards, data-processing rules, automation disclosures, corpus validation, and corrections process. It does not represent a panel of licensed subject-matter experts, and individual site methodologies define the limits of each publication's analysis.

CostByCounty uses this organization as the author when the shared publishing process created the page. The attribution describes a publishing function without asserting an employee count, professional credential, or individual sign-off.

Where Our Data Comes From

All county-level statistics on this site come from primary government sources. We do not republish data from third-party aggregators. Our active source is:

• U.S. Census Bureau, American Community Survey (ACS) 5-Year Estimates — the most comprehensive source of county-level demographic and economic data in the United States. Provides median gross rent, median home value, median monthly owner costs, median household income, rent burden (GRAPI), and related housing-cost metrics for every U.S. county. We use the most recent 5-year release available.

Each source's URL, release date, and pull date are documented on the methodology page. Census data is in the public domain (federal works).

How We Use AI

Per-county pages on this site include a short, AI-generated narrative summary that contextualizes the statistics for that county. The narrative is produced from the same source data shown in the statistics tables on the page. Automated checks compare each output with the source record before publication, and sampled output is inspected for quality assurance. The prompt is constrained to forbid causation claims, financial advice, and any prose that goes beyond what the source statistics support.

We do not use AI to:

• Generate financial advice, investment recommendations, or mortgage guidance.
• Invent statistics, sources, or quotes.
• Write methodology, editorial standards, or correction notices.
• Generate cause-and-effect claims about housing markets that aren't grounded in the source data.

When the underlying data is updated, narratives are regenerated to stay consistent. AI-generated prose is always paired with the source statistics so readers can verify the numbers themselves.

Corrections Policy

If you spot a factual error, misattributed source, or broken citation, use the contact page and include the affected page URL and the specific issue.

Substantive corrections (changes to a statistic, methodology, or claim) are noted in a "Corrections" entry on the page itself with the date of the correction and a short description of what changed. Typographical and formatting fixes are made silently.

How CostByCounty Is Funded

CostByCounty is operated as a distinct publication within ByCounty Network. Funding comes from two transparent sources:

• Display advertising served by Google AdSense and similar networks. Ad placements are clearly labeled and do not influence editorial decisions or which counties we rank where.
• Affiliate links, currently limited to moving-service and mortgage-comparison referrals. Affiliate links are labeled "Sponsored" and never determine which counties we feature on data pages.

We do not accept paid content, sponsored statistics, or advertorials. No data source, advertiser, or affiliate has any influence over the methodology, rankings, or editorial choices on this site.

Update Cadence

Underlying data is refreshed annually, on the release schedule of the U.S. Census Bureau. Narratives are regenerated when the underlying data for a county changes. The methodology and corrections pages document the current method and substantive changes. This editorial-standards page was updated on July 9, 2026.
