Fractal DistributionUSA urban agglomeration were listed in decreasing size and plotted in a log-log display against rank. Thedata shows a fractal distribution. Several extrapolation are possible: (i) Mandelbrot-Zipf, (ii) Fractalparabolic and (iii) Stretched exponential. Perfect self-similarity is a power law or linear fractal in log-logdisplay (size/rank). Imperfect similarity is a curved display. The simplest seems to be the parabolic fractal.Évora, 8-9th May, 200640C. <strong>Cramez</strong>, <strong>Switzerland</strong>ccramez@compuserve.com
