Figure 6

Allotaxonograph comparing US baby girl names for the years 1880 and 2020. This figure is in part a demonstration of how allotaxonographs competently perform when the sizes of two systems differ strongly. For 1968 and 2018 in Fig. 4, the balance of total baby girl names is an almost even 49.2% and 50.8%. By contrast, for 1880 and 2020, these percentages are 5.4% versus 94.6%. The choice of \(\alpha =\infty \) again means that the top names for each year will dominate \(D^{\mathrm{R}}_{\infty }\), regardless of their rank in the comparison year (unless a name has equal rank in both years)
