Country × Country censorship correlation

Pearson correlation across 365-day daily incident vectors for the top 50 most-censored countries (by Atlas Score v2). Pairs that fire together — regional shutdown waves, regime- similar blocking patterns — light up here the day they emerge.

Computed at request time over 1,291 incidents. 1-hour ISR. Source ranking →

Hover any cell for the exact correlation. Diagonal masked (always r = 1). Countries with fewer than two incidents in the window appear as flat zeros — read the cell-count caveat below before interpreting weak signal.

Method & honest caveats

  • Window: 365 days ending today (2026-06-08). Vectors are daily incident counts per country.
  • Countries: top 50 by Atlas Score v2 (50% structural baseline + 50% recent activity).
  • Statistic: Pearson correlation. No significance test surfaced here — small N-days mean even high r can be noise. Treat this as an exploratory surface, not a confirmatory one.
  • The interpretation column above uses a hard-coded regional peer map. A "regional cluster" tag is a hint, not a causal claim.
  • Diagonal is masked. Negative r is rendered blue; positive red; near-zero gray.
