EEOSTAT is a software tool that aids in EEO compliance, useful for HR professionals and employment lawyers.

The five different modules provide quick answers in an easy-to-use format: square and avail provide simple statistical analyses of class-based discrimination claims; paycalc calculates backpay, including compound interest at IRS rates; mh calc provides a statistical test of stratified selections; census eeo tab displays data from the Census EEO Tabulation 2006-2010 (5-year ACS data).

EEOSTAT was created by Jeffrey C. Bannon, an attorney with 40 years of experience handling EEO statistics. He works as Assistant General Counsel with the U.S. Equal Employment Opportunity Commission. EEOSTAT was written in his private capacity.   

How EEOSTAT Works: A charge is filed against your company…

If applicant data are available, you can use square or mh calc to see if any disparity is statistically significant (e.g., women are 20% of the applicants yet only 12% are hired).
If applicant data are not available, get an estimate of female availability (e.g., women are 42% of marketing and sales managers in the Boston metro area) from the included census eeo tab data, and check the disparity with avail.
To get an idea of possible exposure, use paycalc to calculate backpay with interest. Of course, total exposure should also take into account damages, usually a function of the total shortfall (a calculation made by avail and square).
You can print the results from each of the modules or save as a Word, PDF, or text file.

square… a statistical test of selections from a pool

square calculates the statistical significance of disparities in an employment selection process when applicant flow data is available. square computes probability values using the Chi-Square test and, for 2×2 tables, Fisher’s Exact Test. For example, in a race/hiring case, square determines if there is a significant disparity in the rates at which blacks and whites are hired. When this probability is sufficiently low (i.e., .05 or less), the result is said to be statistically significant. Disparities that are statistically significant are generally recognized as evidence of discrimination. › square


avail… a statistical test of selections against availability

avail calculates the statistical significance of disparities in an employment selection process when there is no applicant flow data and protected class availability has been estimated from Census or other labor market data. avail calculates probabilities using the Exact Binomial and the Normal Approximation to the Binomial tests. EEOSTAT now includes data from the Census EEO Tabulation (2006-2010 ACS data) to calculate labor market availability. › avail


paycalc… a tool to calculate backpay with interest

paycalc calculates the amounts of backpay, including interest due aggrieved individuals when you supply the pay they should have earned and the pay they in fact did earn. Amounts are entered either monthly or quarterly, and interest is compounded at IRS interest rates, either monthly or quarterly. Interim earnings are subtracted out.

mh calc

mh_calc… a statistical test of stratified selections

mh-calc allows testing of association between selection and protected status, controlling for up to 18 tiers in a third dimension. It computes the Mantel-Haenszel statistic, common odds ratio, and Breslow-Day test of homogeneity. Odds ratios and Fisher’s Exact Test are computed for each tier. › mh calc

census eeo tab

census eeo tab… data from the Census EEO Tabulation 2006-2010 (5-year ACS data)

census eeo tab provides availability data for detailed occupations and EEO-1 categories, by workplace and residence, for counties, places, and metro areas from the Census EEO Tabulation (2006-2010 ACS data)› census eeo tab
