Impact Chart Demonstration

This site extends the work described in our paper, Impact Charts: A Tool for Identifying Systematic Bias in Social Systems and Data presented at ACM FAccT 24. It allows you to look at the impact of race, ethnicity and median income on eviction rates at the census tract level in 489 counties across the United States where we were able to obtain data. Below the impact charts, we show maps to give you an idea of what data was available and used to plot the charts.

Please select the county you are interested in:

Please select the feature whose impact you want to plot:

Impact

The impact chart below shows the impact of a single feature on the prediction made for each census tract in the county. The green dots are mean predictions for each tract. Each green dot's x coordinate is the value of the feature for the tract. Its y coordinate is the impact.

For each tract there are also 50 gray dots vertically above or below the green dot. These are the predictions of 50 independent models. They function as error bars to give an idea of the variance of the impact.

Data Coverage

In order to make it clear what data went into the impact chart above, we have produced the maps below. For details on how to interpret the maps, please see this post.
