Calculator
Example Data Table
| Occupation | Men | Women |
|---|---|---|
| Managers | 120 | 80 |
| Technicians | 90 | 110 |
| Clerks | 150 | 90 |
| Sales | 80 | 120 |
Formula Used
D = 0.5 × Σ | Ai / A - Bi / B | × 100
Ai means Group A workers in an occupation. Bi means Group B workers in the same occupation. A and B are total workers in each group.
How to Use This Calculator
Enter each occupation name. Add worker counts for both groups. Use comparable groups, such as men and women, or two ethnic groups. Press calculate. Review the index, shares, gaps, table, and graph. Export the result using CSV or PDF buttons.
Understanding Occupational Segregation
What the Index Means
The index of occupational segregation measures how unevenly two groups are spread across jobs. It is often called the index of dissimilarity. The value ranges from zero to one hundred. A score of zero means both groups have the same occupational pattern. A score of one hundred means complete separation. In practical terms, the score estimates the percentage of one group that would need to change occupations to match the other group distribution.
Why It Matters
Occupational segregation can affect pay, promotion, training, and workplace opportunity. Some occupations may have higher wages. Others may offer better stability. When one group is concentrated in lower paid roles, inequality can grow. This calculator helps users study those patterns with clear numbers.
Using Good Data
Use consistent occupation categories. Do not mix departments with job titles unless the categories match. Counts should represent the same period. They should also come from the same workforce population. Clean data gives a stronger result.
Reading the Result
A low score shows similar occupational placement. A middle score suggests visible separation. A high score shows strong imbalance. The table helps identify which occupations create the largest gaps. The graph makes the difference easier to explain.
Practical Uses
Human resource teams can use this tool during workforce reviews. Researchers can compare industries, regions, or periods. Managers can test whether hiring, training, and promotion practices are improving balance. The calculator does not prove discrimination by itself. It highlights patterns that deserve closer review.
FAQs
1. What is occupational segregation?
It means different groups are unevenly distributed across occupations or job categories.
2. What does a high index mean?
A high index means the two groups work in very different occupational patterns.
3. What does zero mean?
Zero means both groups have identical occupational distribution across all listed jobs.
4. Can I compare more than two groups?
This calculator compares two groups. Run separate comparisons for additional groups.
5. Should I use percentages or counts?
Use counts. The calculator converts counts into shares automatically.
6. Is this a legal discrimination test?
No. It is an analytical measure, not a legal conclusion.
7. Which occupations should I include?
Include all relevant occupations from the same workforce population.
8. Can I export the result?
Yes. Use the CSV or PDF buttons after calculating the index.
