# Nevada Campaign Contributions
> A public data transparency site showing Nevada campaign finance records.

## Purpose
This site makes it easy to search and browse campaign contributions and expenditures filed with the Nevada Secretary of State. It covers all levels of government: federal, state, county, and city elections from 2006 to 2025.

## Data
- 570,064 contributions totaling $1.34 billion (after deduplication)
- 370,403 expenditures totaling $1.23 billion (after deduplication)
- 8,778 candidates across all jurisdictions (Federal, State, County, City)
- 1,605 PACs and political committees
- 76,378 individual and corporate contributors (>$1,000 total)
- 22,854 corporate donors
- 1,569 candidates with self-funding data
- Raw data: 743,738 contributions / 480,482 expenditures (before dedup)

## Deduplication
Nevada campaign finance filings include amended reports that supersede prior filings. Raw data contains duplicate contributions from superseded reports and duplicate tuples across non-superseded reports. This site uses deduplicated "clean" views that exclude superseded reports and keep only the highest report_id for each unique contribution tuple. Every excluded row has a verified matching kept row — zero legitimate records lost.

## Audit Flags
The site runs four automated anomaly detectors:
- **Structuring**: Same donor gives 5+ times to same candidate with suspiciously uniform amounts
- **Concentration**: Single donor provides >25% of a candidate's total funding
- **Timing clusters**: 15+ contributions to same candidate on same day
- **Out-of-state**: >60% of candidate's money from outside Nevada
Self-funding (candidate donating to their own campaign) is excluded from structuring and concentration flags using name matching with nickname normalization.
