Negative Event Density Index (NEDI)

About NEDI

The Negative Event Density Index (NEDI) is a data visualization tool designed to quantify the "reporting density" of historical crises.

How it works:

Data Sourcing: Real-time scraping of Wikipedia's chronological archives via the MediaWiki API.
Keyword Filtering: Events are scanned for high-stress identifiers (e.g., war, death, crash, crisis, riot, pandemic).
Density vs. Sentiment: NEDI doesn't measure how "bad" a year felt, but rather the volume of distinct reported incidents. High spikes indicate periods of high geopolitical volatility.

Note on Bias: As Wikipedia's records are more detailed for recent history, NEDI naturally trends upward over time. This tool is best used to compare years within the same 50-year era.

Note on Dates: Due to Wikipedia's naming conventions, dates below AD 150, particularly AD 1-9 may display incorrectly for the time being.
