Why Use Our Files – Pre-processed
• Raw data difficult to manage:– Gigantic files– No “indicators” created (Poverty rate, Median loan
amount, Pct. African American students)– HMDA:
• Thousands of possible indicators to create
– ACS• A nightmare to download and manipulate
• Table/cell references are cumbersome
