| # Methodology |
|
|
| Primary source: https://kentclarkcenter.org/surveys/ |
|
|
| The extractor discovers survey URLs from the Clark Center survey and survey-special sitemaps, checks robots.txt, downloads each poll page, and then prefers the official `Download Poll Data` CSV when present. HTML is still parsed for page metadata, statement text, panel type, source topics, profile URLs, affiliations, visible chart percentages, and fallback votes when no CSV is present. |
|
|
| Run command: `uv run main.py` from this directory. Raw pages and CSVs are cached under `data/raw/`; regenerated deliverables are written at the project root. Use `uv run main.py --refresh` to ignore the cache and redownload all sources. |
|
|
| Unweighted agreement metrics are computed only from the raw vote labels. Confidence-weighted chart values, when exposed by the page JavaScript, are stored in the `weighted_*` columns and are not mixed with the unweighted counts. |
|
|
| Survey-special crisis pages use 0-5 numeric importance ratings rather than agree/disagree votes. They are retained, with numeric ratings mapped to `Other / Not Applicable` and agreement shares left blank. |
|
|
| Allowed issue categories: Monetary policy; Fiscal policy; Taxation; Labor markets; Trade; Immigration; Education; Healthcare; Climate/environment; Financial regulation; Banking; Industrial policy; Antitrust/competition; Housing/urban policy; Growth/productivity; Inequality/redistribution; COVID/pandemic policy; Energy; International economics; Public finance; Political economy; Other |

| ## Coverage Check |
|
|
| - total_poll_pages_discovered: 558 |
| - total_poll_pages_successfully_processed: 558 |
| - total_statements_extracted: 1146 |
| - total_vote_rows_extracted: 50410 |
| - csv_backed_pages: 553 |
| - html_only_or_special_pages: 5 |
| - failed_or_ambiguous_records: 0 |
| |
| ## CSV vs Page Check |
| |
| Sampled 20 CSV-backed poll pages; 20 passed the text/name/count comparison. |
| |
| ## Duplicate Check |
| |
| - duplicate_poll_urls: 0 |
| - duplicate_statement_ids: 0 |
| - duplicate_votes_within_statement: 0 |
|
|
| ## Vote-Label Check |
|
|
| Distinct raw vote labels: 18 |
| Ambiguous labels: 0 |
|
|
| ## Date Check |
|
|
| Missing or ambiguous publication dates: 0 |
|
|
| ## Panel Check |
|
|
| - Europe: 377 statements |
| - Finance: 125 statements |
| - US: 644 statements |
|
|
| ## Reproducibility |
|
|
| 1. `uv sync` to install the locked environment. |
| 2. `uv run main.py` to reuse cached raw sources where available, fetch missing sources, rebuild CSV outputs, run quality checks, and rewrite the methodology and analysis summaries. |
| 3. `uv run main.py --refresh` to force a fresh redownload of all source pages and official CSVs. |
| 4. Inspect `source_log.csv` for every source URL used, whether it was fetched or reused from cache. |
