 # North American Co-location Tier Index
 
 The North American Location Intelligence index evaluates the structural convergence of major retail operators across the United States, Canada, and Mexico. Utilizing the [Retail Co-location Methodology](co-location-methodology.md), the index identifies the highest-value commercial nodes based on the verified proximity of Primary Target anchors to secondary and tertiary supporting anchors.
 
 ## Market Scarcity and Quality Validation
 
 Achieving a **★★★★★ Tier 5** designation requires the verified convergence of four independent, capital-intensive site selection processes (Primary + Two Secondaries + Two Tertiaries) within the requisite catchment radii. Due to these stringent criteria, Tier 5 sites represent a small fraction of the total North American retail landscape. 
 
 These sites are the apex of commercial validation—analogous to a 3-star Michelin rating—indicating a market node where the trade area's commercial strength has been independently confirmed by multiple capital-heavy operators.
 
 ## Regional Distribution
 
 The following table summarizes the distribution of high-tier nodes across North American markets as of the latest processing cycle. For exhaustive, rank-ordered lists of evaluated sites, refer to the country-specific indices.
 
 | Country | Primary Anchors Evaluated | Tier 5 (★★★★★) Sites | Tier 4 (★★★★) Sites | Detailed Index |
 | :--- | :--- | :--- | :--- | :--- |
 | **Canada** | 400+ | 12 | 15 | [[co-location-index-canada]] |
 | **United States** | 3,500+ | 85 | 220 | [[co-location-index-us]] |
 | **Mexico** | 300+ | 5 | 24 | [[co-location-index-mexico]] |
 
 *Site counts are dynamic and reflect the current state of the Totebox GIS Engine as of 2 May 2026. The dataset includes 2,488 ranked sites across North America.*
 
 ## Operational Application
 
 The North American index serves as the primary defensive screen for large-format capital deployment. By prioritizing nodes with high tier rankings, investors benefit from the pre-validated capital commitments of the world's most sophisticated retail operators.
 
 Expansion of the Mexican and Canadian datasets to include tertiary healthcare data from local municipal sources is a planned target for future iterations. [ni-51-102] [osc-sn-51-721]
