Understand the dataset¶

There are three datasets that are available on the Chicago Data Portal:

1. Socioeconomic Indicators in Chicago¶

This dataset contains a selection of six socioeconomic indicators of public health significance and a “hardship index,” for each Chicago community area, for the years 2008 – 2012.

A detailed description of this dataset and the original dataset can be obtained from the Chicago Data Portal at this link.
