cdfidata 0.1.8

ETL pipeline for US Treasury CDFI Fund public datasets — TLR, CLR, and Awards data

cdfi-data 🏦

ETL pipeline for US Treasury CDFI Fund public datasets.

Download, clean, and analyze Transaction Level Report (TLR), Consumer Loan Report (CLR), and Awards data from the US Department of Treasury's CDFI Fund — in one line of Python.

---

Why cdfi-data?

The CDFI Fund releases massive public datasets covering millions of loans and investments in low-income communities. But the raw files are messy, inconsistently formatted, and require significant cleaning before analysis. cdfi-data standardizes the entire pipeline.

Installation

pip install cdfidata

Quickstart

from cdfidata import TLRLoader, CLRLoader, AwardsLoader

# Load TLR transaction data (downloads & caches automatically)
tlr = TLRLoader()
df = tlr.load(year=2022)

# Filter to Illinois
il = tlr.filter_state("IL")

# Filter by loan type and amount
small_biz = tlr.filter_loan_type("Business")
large = tlr.filter_amount(min_amount=500_000)

# Summary stats
tlr.summary()

# Export
tlr.to_csv("cdfi_transactions.csv")
tlr.to_sqlite("cdfi.db", table="tlr")
