We saw in Table 3.1 that black drivers were 63 percent more likely to be pulled over than whites, based on population statistics. If blacks drive, on average, just 84 miles for every 100 miles that whites drive (e.g., based on the estimates in Table 3.3), then the driving-adjusted Stop Rate Ratio for blacks compared to whites would be: 1.63 / .84, or 1.94. For Hispanics, the 1.02 ratio of stop rates compared to whites, adjusted for driving, is 1.24.
