Population growth 2010 This “back-to-back” stem-andleaf plot displays two data sets at once—one going to the left, one to the right. The plot compares the percent change in population for two regions of the United States (based on census figures for 2000 and 2010). The fastest growing state was Nevada at 35%. To show the distributions better, this display breaks each stem into two lines, putting leaves 0–4 on one stem and leaves 5–9 on the other.
