• All race and sex groups combined by detailed industry classifications; • Detailed race and sex groups by all industry classifications combined; and • Detailed race and sex by detailed industry classifications. The utilization results will be used to form the weights for the availability analysis. Task: Perform Availability Analysis Based on the product and geographic utilization data in the Final Contract Data File, we will calculate weighted M/WBE availability estimates of ready, willing and able firms in the City's markets. We will apply the "Custom Census" methodology using the following steps: 1. Acquire all government M/W/DBE directories and listings from private entities that maintain such listings. 2. Prepare a final list of all the combined collected directories that consolidates information across fields, resolves field conflicts, and removes duplicates. 3. Using the relevant geographic and product market definitions identified previously, define a subset of business data to be licensed from Dun & Bradstreet's/Hoover's MarketPlace database to create the Master Business List. 4. Merge the Master M/W/DBE Directory with the Master Business List to create a final Merged Business List of firms in the relevant markets. We will assign any missing industry codes or race/gender status. The Merged Business List will be the available universe of relevant firms for the study. We will assign race and sex to any firm not already classified. We will produce estimates of women and minority business availability in the city's markets for: • All race and sex groups combined, and all industry groups combined. • All race and sex groups combined by detailed industry. • All detailed industry groups combined by detailed race and sex. • Detailed race and sex by detailed industry groups. Task: Perform Disparity Analyses Using the M/WBE utilization estimates and the M/WBE availability estimates, CHA will calculate a disparity index using regression analyses (statistical methods approved by the courts). The disparity index will be formed by dividing M/WBE availability into M/WBE utilization and multiplying the result by 100. CHA will produce statistical comparisons of M/WBE availability with the utilization of M/WBEs on city contracts for the study period; produce disparity indices for all race, sex, and detailed industry categories; and apply statistical significance tests, to the extent permitted by the sample sizes. If supported by sufficient observations in the database, a separate disparity index will be calculated for; 0 All race and sex groups combined, and all industry groups combined.
