# Language Data
Curated linguistic datasets covering 23,740 languages. Pulls from Glottolog, WALS, PHOIBLE, and Joshua Project, plus original integration work combining them into a single queryable format.

| `glottolog_coordinates.json` | 21,329 languoids | 3.8 MB | [Glottolog](https://glottolog.org) | CC-BY-4.0 |
| `glottolog_languoid.csv` | 23,740 languoids | 1.8 MB | [Glottolog](https://glottolog.org) | CC-BY-4.0 |
| `phoible.csv` | 105,484 phonemes | 24 MB | [PHOIBLE](https://phoible.org) | CC-BY-SA-3.0 |
| `wals_languages.csv` | 3,573 languages | 460 KB | [WALS](https://wals.info) | CC-BY-4.0 |

### Subdirectories
**`language-families/`** -- Language family trees, Proto-Indo-European reconstructions, speaker counts. Restructured from Glottolog with enrichment from multiple sources. 10 JSON files covering family hierarchies up to 18 levels deep.
**`historical-corpora/`** -- CLMET historical English corpus metadata.
**`lemmatization/`** -- Historical lemma mappings (738 entries) for normalizing older English texts.
**`reference-corpora/`** -- Brown Corpus part-of-speech statistics.
## The Integrated Dataset
`world_languages_integrated.json` is the main original contribution. It merges four sources by ISO 639-3 code:
- **Glottolog** -- coordinates, family classification, macroarea (7,040 languages)
- **Joshua Project** -- speaker populations, demographics (7,130 languages)
- **Language history** -- family tree positions, historical periods (198 languages)
- **US indigenous** -- endangerment status, revitalization efforts (13 languages)
```python
import json
with open("world_languages_integrated.json") as f:
languages = json.load(f)
# Each record looks like:
# {
# "iso_639_3": "eng",
# "name": "English",
# "glottolog": { "latitude": 53.0, "longitude": -1.0, "family_name": "Indo-European", ... },
# "joshua_project": { "population": 379007140, "countries": [...], ... },
# "speaker_count": { "count": 379007140, "source": "joshua_project_aggregated", ... },
# "data_sources": ["joshua_project", "glottolog"]
# }
# Find endangered languages with coordinates
endangered = [
lang for lang in languages
if lang.get("glottolog", {}).get("latitude")
and lang.get("speaker_count", {}).get("count", float("inf")) < 1000
]
```
