Evan Brooks
Data Editor
Data editor for the ByCounty Network, responsible for methodology documentation, source review, and editorial QA on county-level reports built from public datasets.
Evan Brooks is the editorial byline for ByCounty Network data review, methodology maintenance, and source attribution across the network.
The role is the data-editor role, not the subject-matter-expert role. ByCounty designs data pipelines that pull each dataset, documents the methodology behind every composite score and ranking, spot-checks generated narratives against the underlying statistics before publication, and records methodology changes. The sites are transparent data utilities, not professional advisory services.
When a feature genuinely requires domain expertise — a public-health analyst weighing in on CDC measure choice, a CPA reviewing a property-tax explainer — ByCounty uses a named co-byline reviewer rather than presenting the data editor as a domain-credentialed professional. The reviewer commitment for each site is documented on that site's editorial-standards page, including the recruit status when no domain reviewer is currently in place.
Every statistic on the site is traceable to a primary source, every methodology decision is documented, and every page lists a "Last reviewed" date where editorial review applies.
