Figure 4-5. Top: points indicate where each data point is; bottom: the same data with a log y-axis
With the log y-axis, you can see that the rate of proportional change has increased in the last
thousand years. The estimates for the years before 0 have a roughly constant rate of change
of 10 times per 5,000 years. In the most recent 1,000 years, the population has increased at a
much faster rate. We can also see that the population estimates are much more frequent in recent
times—and probably more accurate!
