Specification |
STEP 1: Enrolled on the last day of DQ report month Define the eligible population from segment ENROLLMENT-TIME-SPAN-ELG00021 by keeping active records that satisfy the following criteria: 1. ENROLLMENT-EFF-DATE <= last day of the DQ report month 2. ENROLLMENT-END-DATE >= last day of the DQ report month OR missing 3. MSIS-IDENTIFICATION-NUM is not missing STEP 2: Race information on the last day of DQ report month Using the MSIS IDs that meet the criteria from STEP 1, join to segment RACE-INFORMATION-ELG00016 by keeping active records that satisfy the following criteria: 1a. RACE-DECLARATION-EFF-DATE <= last day of the DQ report month 2a. RACE-DECLARATION-END-DATE >= last day of the DQ report month OR missing OR 1b. RACE-DECLARATION-EFF-DATE is missing 2b. RACE-DECLARATION-END-DATE is missing STEP 3: Non-missing race Of the MSIS IDs that meet the criteria from STEP 2, further refine the population by keeping records with: 1. RACE is non-missing STEP 4: Percent race for the current month 1. For each distinct value of race, set the number of unique MSIS IDs as Numerator_Count_By_Value. 2. Sum the total number of unique MSIS IDs within each valid value of ethnicity and set as Denominator_Count. Note that Denominator_Count should also equal to the count of MSIS IDs from STEP 3. 3. For each distinct value of race, calculate Percent_Current_Month as the ratio of Numerator_Count_By_Value over Denominator_Count. STEP 5: Percent race for the previous month Repeat STEP 1 through STEP 4 for the previous month. For each distinct value of race, set the percent of race for the previous month as Percent_Prior_Month_1. STEP 6: Calculate change between months For each frequency percent, calculate Frequency_Change as the absolute value of (Percent_Current_Month – Percent_Prior_Month_1) / 2. Note that Frequency_Change is a vector of frequencies. STEP 7: Calculate index of dissimilarity Calculate the index of dissimilarity by summing Frequency_Change across all frequencies |
