Figure A1.
The horizontal axis is labeled “Digit” and ranges from 1 to 9 in increments of 1. The vertical axis is labeled “Percent” and ranges from 0 to 35 percent in increments of 5 percent. Two series are shown as indicated in the legend: Fibonacci empirical distribution and Benford’s law. The bars represent the empirical distribution, and a line represents Benford’s law. The values show a decreasing pattern from digit 1 to digit 9. The bars start near approximately 30 percent at digit 1, drop to approximately 18 percent at digit 2, then continue decreasing gradually to approximately 4 to 5 percent at digit 9. The line closely follows the same downward trend across all digits. Note: All numerical values are approximated.First-digit distribution of Fibonacci numbers versus Benford’s law.
