SDLA District Systems Initiative

Which Districts Share the Most Systems?

Explore California district pairs ranked by the number of systems they have in common across the SDLA catalog.

About the data: These comparisons use current, published relationships recorded in SDLA. Coverage varies by district and may not represent its complete system inventory. Results include unverified relationships unless you select verified records only.

Explore the rankings

How to read these comparisons

Shared systems: The number of matching category–product relationships. A product recorded under two categories counts once in each category. Duplicate records within the same category count once.

Smaller inventory overlap: Shared systems divided by the smaller district’s recorded total. This can reach 100% even when district inventories differ greatly.

Combined inventory similarity (Jaccard): Shared systems divided by the combined distinct inventory: total A + total B − shared systems.

Instruction / Curriculum: Include all systems, count only products classified in Instruction / Curriculum, or leave that category out. All counts, totals, percentages, verification summaries, and shared-system lists use the selected scope. This filter uses the systems catalog category, not the separate curriculum catalog.

Verification: “Verified records” includes the SDLA verified and high-confidence statuses. It describes the records, rather than guaranteeing present-day district use. Confirm details with the district before making decisions.

Ranking: Highest shared count first. Ties use combined inventory similarity, then smaller inventory overlap, followed by district names. Filtering or selecting verified records only recalculates the ranking and totals.
