+# India Census 2011 — District Level
+
+Clean, versioned district-level data from India's 2011 Census. 
+640 districts. 29 columns. Zero missing values. Ready for pandas.
+
+## Quick Start
+
+```python
+import pandas as pd
+from huggingface_hub import hf_hub_download
+
+path = hf_hub_download(
+    repo_id="indiaset/census-2011",
+    filename="census_2011_districts_final.parquet",
+    repo_type="dataset"
+)
+df = pd.read_parquet(path)
+print(df.shape)  # (640, 29)
+```
+
+## What's In This Dataset
+
+One row per district. All 640 districts of India as they existed 
+on Census night — midnight of February 28, 2011.

+

+the official Census 2011 total for India. Zero discrepancy.
+
+## Key Insights
+
+- Most literate district: Pathanamthitta, Kerala — 88.74%
+- Least literate district: Alirajpur, Madhya Pradesh — 28.77%
+- Literacy gap across India: 60 percentage points
+- National sex ratio: 943 females per 1000 males
+
+## Known Limitations
+
+⚠️ This data reflects 2011 boundaries. Key things to know:
+
+- **Telangana does not exist** — it was carved out of Andhra 
+  Pradesh in 2014. All Telangana districts appear under 
+  Andhra Pradesh here.
+- **New districts created after 2011 are not present** — 
+  India had 640 districts in 2011, now has 800+.
+- **Population figures are from 2011** — use for structural 
+  comparisons, not current headcounts.
+- **Yanam and Mahe** (Puducherry enclaves) LGD codes were 
+  manually verified and patched — not in the LGD export.
