Adverse Impact Calculator

Adverse impact, also known as disparate impact, is a concept used in employment discrimination law. It refers to employment practices that appear neutral but have a disproportionate effect on a certain group.

Historical Background

The concept of adverse impact has its roots in the Civil Rights Act of 1964, specifically Title VII, which prohibits employment discrimination. It became a key element in employment law to ensure fairness in hiring and employment practices.

Calculation Formula

Adverse impact is calculated using the following formula:

\[ \text{Adverse Impact} = \frac{\text{Rate of Selection for Lesser-Represented Group}}{\text{Rate of Selection for Majority Group}} \]

Example Calculation

Consider a scenario where:

• The Majority Group's Rate of Selection is 60%.
• The Minimum Percentage for Lesser-Represented Groups to be hired is 40%.

Using the formula:

\[ \text{Adverse Impact} = \frac{40\%}{60\%} = 0.6667 \]

An adverse impact ratio less than 0.80 (or 80%) is generally considered indicative of potential discrimination.

Importance and Usage Scenarios

Understanding and calculating adverse impact is crucial for:

1. Legal Compliance: Ensuring hiring practices are compliant with anti-discrimination laws.
2. Diversity and Inclusion: Promoting fair hiring practices and diverse workplaces.
3. Organizational Analysis: Identifying potential biases in hiring and employment practices.
