# 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
```python
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")
```
