EthniData

State-of-the-art name analysis engine — predict nationality, ethnicity, gender, language, religion, and region from first/last names. 5.9M+ records, 238 countries, explainable AI, morphology detection, and synthetic data generation.

Installation

pip install ethnidata

Quick Start

from ethnidata import EthniData

ed = EthniData()

# Predict nationality from first name
result = ed.predict_nationality("Ahmet")
print(result["nationality"])     # Turkey
print(result["confidence"])      # 0.87
print(result["region"])          # Middle East

# With full explainability
result = ed.predict_nationality("Yılmaz", name_type="last", explain=True)
print(result["ambiguity_score"])        # 0.21 (low = confident)
print(result["confidence_level"])       # High
print(result["morphology_signal"])      # {'primary_pattern': 'maz_suffix', ...}
print(result["explanation"]["why"])     # 'Suffix -maz is strongly Turkish/Azerbaijani'

Nationality Prediction

from ethnidata import EthniData

ed = EthniData()

# First name
r = ed.predict_nationality("Hiroshi")
print(r["nationality"])    # Japan
print(r["confidence"])     # 0.91

# With explanation
r = ed.predict_nationality("O'Brien", name_type="last", explain=True)
print(r["explanation"]["why"])  # "O' prefix is a strong Gaelic/Irish marker"
print(r["morphology_signal"])   # {'primary_pattern': "o'", 'pattern_type': 'gaelic'}

Full Name Analysis

from ethnidata import EthniData

ed = EthniData()

# Analyze first + last name together
result = ed.predict_full_name("Mehmet", "Yılmaz")
print(result["nationality"])   # Turkey
print(result["confidence"])    # 0.95
print(result["gender"])        # Male

print(result["language"])      # Turkish

# With explainability
result = ed.predict_full_name("John", "Smith", explain=True)
print(result["explanation"]["first_name_signal"])  # 'English/Christian'
print(result["explanation"]["last_name_signal"])   # 'Anglo-Saxon occupational'
print(result["ambiguity_score"])   # 0.15 (highly confident)

Gender Prediction

from ethnidata import EthniData

ed = EthniData()

for name in ["Maria", "Carlos", "Alex", "Kim"]:
    r = ed.predict_nationality(name)
    print(f"{name:10s} → gender: {r.get('gender', 'N/A'):8s}  confidence: {r.get('gender_confidence', 0):.2f}")
# Maria      → gender: Female    confidence: 0.97
# Carlos     → gender: Male      confidence: 0.94
# Alex       → gender: Neutral   confidence: 0.52
# Kim        → gender: Neutral   confidence: 0.61

Religion Prediction

from ethnidata import EthniData

ed = EthniData()

names = [
    ("Fatima", "Al-Rashid"),
    ("Arjun", "Sharma"),
    ("David", "Cohen"),
    ("Harpreet", "Singh"),
]

for first, last in names:
    r = ed.predict_full_name(first, last)
    print(f"{first} {last}: {r['religion']} ({r['nationality']})")
# Fatima Al-Rashid: Islam (Saudi Arabia)
# Arjun Sharma: Hinduism (India)
# David Cohen: Judaism (Israel)
# Harpreet Singh: Sikhism (India)

Morphology Detection

from ethnidata.morphology import MorphologyEngine, NameFeatureExtractor

# Detect cultural pattern from name morphology alone
signal = MorphologyEngine.get_morphological_signal("O'Connor", "last")
print(signal)
# {'primary_pattern': "o'", 'pattern_type': 'gaelic', 'cultural_group': 'Irish', 'confidence': 0.88}

signal = MorphologyEngine.get_morphological_signal("Kowalski", "last")
print(signal)
# {'primary_pattern': 'ski_suffix', 'pattern_type': 'slavic', 'cultural_group': 'Polish', ...}

# Extract morphological features for analysis
features = NameFeatureExtractor.extract("Nakamura", "last")
print(features["suffix"])           # 'mura'
print(features["length"])           # 8
print(features["phonetic_family"])  # 'japanese'

Ambiguity Scoring

from ethnidata import EthniData

ed = EthniData()

# Shannon entropy: 0.0 = certain, 1.0 = maximally ambiguous
names = ["Yılmaz", "Kim", "Alex", "Mohammed"]
for name in names:
    r = ed.predict_nationality(name, explain=True)
    print(f"{name:12s}  ambiguity={r['ambiguity_score']:.2f}  level={r['confidence_level']}")
# Yılmaz       ambiguity=0.11  level=High
# Kim          ambiguity=0.74  level=Low
# Alex         ambiguity=0.68  level=Low
# Mohammed     ambiguity=0.22  level=High

Synthetic Data Generation

from ethnidata import EthniData, SyntheticDataEngine, SyntheticConfig

ed = EthniData()

# Generate privacy-safe synthetic name dataset for Turkish names
engine = SyntheticDataEngine(ed.freq_provider)
config = SyntheticConfig(size=1000, country="TUR", include_gender=True)
records = engine.generate(config)

print(f"Generated {len(records)} synthetic records")
for r in records[:3]:
    print(f"  {r.first_name} {r.last_name} ({r.gender}) — {r.nationality}")
# Mehmet Yılmaz (Male) — Turkey
# Fatma Demir (Female) — Turkey
# Ali Kaya (Male) — Turkey

# Generate multi-country dataset
config_multi = SyntheticConfig(
    size=5000,
    countries=["USA", "DEU", "JPN", "BRA"],
    balanced=True,
)
dataset = engine.generate(config_multi)

Explainability Engine

from ethnidata import ExplainabilityEngine, EthniData

ed = EthniData()

result = ed.predict_full_name("Giuseppe", "Rossi", explain=True)

print(result["explanation"]["why"])
# 'Giuseppe is a classic Italian form of Joseph; Rossi (pl. of rosso) is the most common Italian surname'

print(result["explanation"]["confidence_breakdown"])
# {'database_frequency': 0.91, 'morphology_match': 0.88, 'phonetic_score': 0.85}

print(result["explanation"]["similar_names"])
# ['Gioseppe', 'Beppe', 'Peppe'] — Italian variants

Batch Processing

import pandas as pd
from ethnidata import EthniData

ed = EthniData()

df = pd.DataFrame({
    "first_name": ["Ahmet", "Maria", "Hiroshi", "John"],
    "last_name":  ["Yılmaz", "Garcia", "Tanaka", "Smith"],
})

results = []
for _, row in df.iterrows():
    r = ed.predict_full_name(row["first_name"], row["last_name"])
    results.append({
        "nationality": r["nationality"],
        "religion":    r.get("religion", "Unknown"),
        "confidence":  r["confidence"],
    })

df = df.join(pd.DataFrame(results))
print(df[["first_name", "last_name", "nationality", "religion", "confidence"]])

Ethical Use

EthniData is designed for:

• Research and analytics: population studies, historical data analysis
• Data quality: enriching and validating name-country datasets
• Privacy testing: generating synthetic test data instead of using real PII
• Academic use: reproducible, transparent, citable

Not intended for individual profiling, discrimination, or surveillance. All predictions are probabilistic — treat with appropriate uncertainty.
