About this data

ScanGov scans the homepage of each county government site on our county list in New Hampshire. Scores come from the checks listed on standards.scangov.org. Sites were scanned between 9/11/2026 and 9/17/2026; each site's report shows its own scan date. A site counts as fully scanned when its homepage returned successfully and sent the scanner its page content. Averages, grade shares, failure rates, and ranks use fully scanned sites only. Grades follow the ScanGov grade scale, and rank follows the ScanGov ranking method. The full dataset, including every county's raw results, is published in the ScanGov data repository.
