Meteorites vs UFOs: Detection Bias Study

Both meteorite falls and UFO sightings depend on someone looking up at the right time. This dataset puts them side by side, same timeframe, same geography, to see where the patterns diverge.

Three tables in one JSON file:

Section	Records	What It Is
`temporal_comparison`	124	Year-by-year meteorite falls vs UFO reports (1900-2023)
`state_comparison`	58	State-level counts and UFO-to-meteorite ratios
`meteorite_detail`	1,097	Individual witnessed falls with US state assignment

Dataset Structure

See demo_notebook.ipynb for data exploration examples.

Usage

import json

with open('meteorites_ufos_detection_bias.json') as f:
    data = json.load(f)

# Year-by-year comparison
for row in data['temporal_comparison'][-10:]:
    print(f"{row['year']}: {row['meteorite_falls']} falls, {row['ufo_sightings']:,} UFO reports")

# Which states have the highest UFO-to-meteorite ratios?
ranked = sorted(
    [s for s in data['state_comparison'] if s['ufo_per_meteorite']],
    key=lambda x: x['ufo_per_meteorite'],
    reverse=True
)
for s in ranked[:5]:
    print(f"{s['state']}: {s['ufo_per_meteorite']:,.0f} UFO reports per meteorite fall")
