Synthea Synthetic Patient Records (575K Patients)

A comprehensive synthetic healthcare dataset containing 575,415 patients with complete medical histories, generated using Synthea — the gold standard for synthetic EHR data.

No real patient data. Fully synthetic, HIPAA-safe, and ready for ML research and education.

Why This Dataset?

• 575K patients with realistic demographics, conditions, medications, and encounters
• Privacy-safe: No real PHI — use freely in research, teaching, and production
• Complete records: Conditions, medications, procedures, encounters, observations, and more
• Parquet format: Fast loading with pandas, polars, or HF datasets

Quick Start

from datasets import load_dataset

# Load the full dataset
ds = load_dataset("richardyoung/synthea-575k-patients")

# Or load a specific table
patients = load_dataset("richardyoung/synthea-575k-patients", data_files="patients.parquet")

# Explore
print(f"Patients: {len(ds['train']):,}")
print(ds['train'].column_names)
print(ds['train'][0])

With pandas

import pandas as pd
from huggingface_hub import hf_hub_download

path = hf_hub_download(
    repo_id="richardyoung/synthea-575k-patients",
    filename="patients.parquet",
    repo_type="dataset",
)
df = pd.read_parquet(path)
print(df.head())
print(f"Shape: {df.shape}")
