| Figure 2. Dow Jones industrial average rose relatively slowly over most of the 1960s and '70s; it then climbed sharply during the 1980s and '90s. This history is well illustrated by a simple graph with linear scales (top). Plotting the Dow using logarithmic scales (bottom), as Deevey and others have done for population growth, completely obscures the pattern of change: On casual inspection of the bottom graph, the stock average appears to be approaching an asymptote. |
