microdf
Weighted pandas DataFrames and Series for survey microdata analysis.
Overview
microdf provides MicroDataFrame and MicroSeries classes that extend pandas functionality with integrated weighting support, essential for accurate survey data analysis.
Key Features
- MicroDataFrame: A pandas DataFrame with an integrated weight column
- MicroSeries: A pandas Series with integrated weights
- Weighted operations: All aggregations (sum, mean, median, etc.) automatically use weights
- Inequality metrics: Built-in Gini coefficient calculation
- Poverty analysis: Integrated poverty rate and gap calculations
Installation
Install with:
pip install microdf-python
Or for development:
pip install git+https://github.com/PolicyEngine/microdf.git
Usage
import microdf as mdf
import pandas as pd
# Create sample data with weights
df = pd.DataFrame(
{"income": [10_000, 20_000, 30_000, 40_000, 50_000], "weights": [1, 2, 3, 2, 1]}
)
# Create a MicroDataFrame
mdf_df = mdf.MicroDataFrame(df, weights="weights")
# All operations are weight-aware
print(mdf_df.income.mean()) # Weighted mean
print(mdf_df.income.gini()) # Gini coefficient
