Case-by-Case Empirical Analysis

One page per case

Every opinion on OpenJurist has a companion empirical-analysis page — append /empirical-analysis to any case URL, or follow the link from the case page itself. Where a case page gives you the opinion's text, its analysis page gives you the opinion's consequences: everything the rest of the corpus says about it, gathered onto one linkable, citable page.

What it measures

• Citation profile — how many later decisions cite the case, how often the Supreme Court has, how many states follow it, and when it was most recently cited, broken down by court class.
• Citations over time — the case's influence decade by decade, so you can see a precedent rising, plateauing, or fading long before anyone writes that story down.
• The appellate journey — what decision the case reviewed and what reviewed it in turn, linked up and down the chain.
• Relationships — the statutes the case applies, the authorities it relies on, and the cases it is most often cited alongside.
• Most-quoted passages — the exact sentences later courts lift from the opinion, each verified word-for-word against the source. How passages are verified →
• Treatment — whether later courts followed, distinguished, criticized, or overruled the case, classified from each citing court's own sentence.

See it live

• Miranda v. Arizona, 384 U.S. 436 (1966) →A case cited so widely that its profile spans every court class — watch the citations climb decade by decade and see which sentences do the work.
• Strickland v. Washington, 466 U.S. 668 (1984) →The ineffective-assistance standard — one of the most-quoted opinions in the corpus, with the exact passages later courts keep lifting.
• Brown v. Board of Education, 347 U.S. 483 (1954) →A landmark whose empirical record shows both its citation reach and the earlier precedent it overruled.
• Roe v. Wade, 410 U.S. 113 (1973) →An overruled case — the analysis shows the full arc: decades of citations, then the overruling decision, all on one page.

Held to the record

Every number on an analysis page is computed from citation links found in published opinions — never estimated, never editorialized. Quoted passages appear only when the exact words are found in the citing decision, treatment labels come from the citing court's own sentence, and overrulings link to the overruling decision so you can read it yourself. The limits are published too: see the case-status methodology and our editorial and sourcing policy.
