This event describes demographic trends (immigration decline, population slowdown) that may affect future congressional redistricting. Election driver scores 3.5 because redistricting impacts representation and political power, but the mechanism is indirect and speculative. Civil_rights scores 1.5 for potential representation impacts on immigrant communities. The mechanism_modifier is 1.15 (election_admin_change affects process infrastructure). Federal scope yields 1.3 modifier. Durability 1.2 (demographic trends are long-term), reversibility 1.1 (trends can shift with policy), precedent 0.9 (normal demographic fluctuation). Base score 9.8 × 1.19 severity × 1.15 mechanism × 1.3 scope = 16.7. B-score: Layer1 modest (demographic stories lack viral potential), Layer2 shows some timing/narrative elements around redistricting cycles. Intentionality 4 (timing, framing). Final B 11.8. Classification: A<25, no direct constitutional mechanism (demographic change itself isn't governmental action), highly speculative about future impacts, multiple noise indicators present. This is demographic trend reporting with uncertain electoral implications, not concrete constitutional damage.
