Report cumulative response rates

Make cumulative recruitment‑to‑completion response rate (the product of recruitment response and survey response after attrition) a routine, prominent line in every survey methodology section so readers can assess representativeness at a glance. The single numeric figure complements standard margin‑of‑error and weighting disclosures and highlights long‑term-panel attrition or recruitment shortfalls. — Standardizing and publishing cumulative response rates would improve public and editorial scrutiny of surveys, making it harder to treat headline percentages as equally credible across different polls.
