Calculators & Tools
Female Delusion Calculator
The Female Delusion Calculator estimates the percentage of single men in the United States who match a specified combination of criteria including age range, height, income level, and relationship status, using US Census Bureau demographic data. It frames partner search criteria as a probability question so users can understand how rare or common their ideal partner profile is within the actual population. Use it to assess the statistical prevalence of specific demographic profiles.
Gini Coefficient Calculator
Computes the Gini coefficient from either individual income values or grouped bracket data. Returns the standard Gini, bias-corrected Gini (G* = G × n/(n−1)), Palma ratio, quintile income shares, and a comparison against World Bank country-level Gini data.
Theil Index Calculator
The Theil Index Calculator computes Theil T (GE(1)) and Theil L (Mean Log Deviation) from individual income values or grouped data. It decomposes total inequality into within-group and between-group components when group labels are provided, and outputs the normalized Theil T, Atkinson equivalent, and Gini coefficient alongside the Theil scores for a complete inequality profile.
Index of Dissimilarity Calculator
The Index of Dissimilarity Calculator measures the spatial evenness of two population groups across any set of geographic areas: neighbourhoods, census tracts, schools, or wards. Enter the group count for each area and the calculator returns D on a 0-to-1 scale, a per-area contribution breakdown identifying which areas drive the segregation most, and a comparison against 2020 US city data from the Brown University US2020 project.
Atkinson Index Calculator
The Atkinson Index Calculator measures income inequality using a welfare-based formula with a configurable inequality aversion parameter (epsilon). Enter any list of income values and set epsilon between 0.1 and 3.0 to control whether the index is most sensitive to the top, middle, or bottom of the distribution. The calculator returns the Atkinson index, the Equally Distributed Equivalent income, a welfare sacrifice percentage, a multi-epsilon comparison panel, and a country benchmark table based on LIS and UNDP data.
Exposure & Isolation Index Calculator
The Exposure and Isolation Index Calculator measures the degree of contact and separation between two population groups across any set of geographic areas. Enter group counts for each neighbourhood or zone and the calculator returns the isolation index (xPx) and cross-group exposure index (xPy) for both groups, an adjusted isolation index corrected for group size, an asymmetry panel explaining why xPy does not equal yPx, a per-area contribution breakdown showing which areas drive isolation most, and a comparison against approximate 2020 US metro data from the Brown University US2020 project.
