Dissimilarity Index: 0
The Dissimilarity Index Calculator measures the level of segregation between two groups within a specific geographic region. It is widely used in sociology, urban planning, and economics to analyze patterns of residential segregation. The index helps researchers and policymakers understand how evenly or unevenly two groups are distributed across different areas.
A dissimilarity index value of 0 indicates complete integration, meaning the two groups are evenly distributed. A value of 1 represents total segregation, where each area contains only one group. This calculation is essential for evaluating demographic patterns and assessing inequalities in housing, education, and employment opportunities.
Formula of Dissimilarity Index Calculator
The Dissimilarity Index is calculated using the following formula:
D = (1 / 2) × Σ | (Ai / A) - (Bi / B) |
Where:
- Ai = Population of group A in area i
- A = Total population of group A in the entire region
- Bi = Population of group B in area i
- B = Total population of group B in the entire region
This formula calculates the proportion of one group that would need to relocate to achieve an even distribution. The sum of absolute differences across all areas is divided by 2 to normalize the result between 0 and 1.
Interpretation of Results:
- 0.00 - 0.30 → Low segregation
- 0.31 - 0.60 → Moderate segregation
- 0.61 - 1.00 → High segregation

Example of Dissimilarity Index Calculator
Example Calculation:
Consider a city with two ethnic groups, where:
- Group A:
- Population in District 1: 400
- Population in District 2: 600
- Total Population: 1000
- Group B:
- Population in District 1: 500
- Population in District 2: 1500
- Total Population: 2000
Using the formula:
D = (1 / 2) × [(400 / 1000) - (500 / 2000)] + [(600 / 1000) - (1500 / 2000)]
D = (1 / 2) × [0.15 - 0.15] = 0
A result of 0 means complete integration, indicating that both groups are evenly distribute across the districts.
Most Common FAQs
A high Dissimilarity Index (close to 1) suggests strong segregation, meaning one group is concentrate in certain areas while the other is in separate locations. This often reflects social and economic inequalities.
The index is commonly use in urban planning, policy analysis, and social research to assess segregation patterns and guide policies for fair housing, education access, and economic opportunities.
Yes, the index applies to income levels, education distribution, and other demographic factors, helping researchers study inequality across various dimensions.
