Logan Johnson
Founder & Data Editor
Builder and data editor of the ByCounty Network. I publish county-level data sourced exclusively from federal agencies — and I am personally accountable for every methodology decision on this site.
Logan Johnson is the founder and data editor of the ByCounty Network — a family of independent data-journalism sites that publish county-level statistics from primary U.S. government sources: U.S. Census ACS, FBI UCR, CDC, FEMA NRI, NCES, EPA, NOAA, USDA, and USASpending.gov.
His role is the data-editor role, not the subject-matter-expert role. He designs the data pipelines that pull each dataset, sets the methodology behind every composite score and ranking, spot-checks AI-generated narratives against the underlying statistics before publication, and signs off on every methodology change. He is not a CPA, physician, criminologist, real-estate broker, or other domain-credentialed professional. The site is a transparent data utility, not a professional advisory service.
When a feature genuinely requires domain expertise — a public-health analyst weighing in on CDC measure choice, a CPA reviewing a property-tax explainer — Logan recruits a named co-byline reviewer rather than fabricating credentials. 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.
Outside the network, Logan has spent the last several years building data infrastructure for logistics and operations teams — work that translates directly into the pipeline discipline applied here: every statistic on the site is traceable to a primary source, every methodology decision is documented, and every page lists a "Last reviewed" date.
