The original version of this article unfortunately contained an error in the Acknowledgement section; the given name Sarah was inadvertently published as Susan. The corrected text has been given below:

Acknowledgements We much appreciate the very helpful assistance provided by Sarah Foster Logoyda and Gursmeep Hundal while they were studying for a Master of Science degree in Public Policy and Management at the Heinz College of Carnegie Mellon University.

In addition, the numerator and the denominator of Eq. 1 were incorrectly published in the original article. The corrected version is given below:

$${\text{X}} = \frac{{\text{black percentage of arrestees} * (1 - {\text{black percentage of prisoners}})}}{{\text{black percentage in prisons} * (1 - {\text{black percentage of arrestees}}) }}$$

or

$${\text{X}} = \frac{\text{A*(1 - P)}}{\text{P}*(1 - \text{A})}$$
