About this research
CostInspector publishes original data reports to help homeowners, journalists, and researchers understand the US home-services market. Every report is built from public-domain data sources — U.S. Census Bureau, Bureau of Labor Statistics, Energy Information Administration, and others — and is free to read, cite, and embed.
We show our work: each report links to its primary data source, documents its methodology, and provides a machine-readable dataset schema (schema.org/Dataset) for automated discovery.
