The Northern Ireland population grew by 3.12% between 2011 and 2017. What were the changes by the four age groups reported?
library(UpAndDownPlots)
popx <- ud_prep(NIpop, v1="y2011", v2="y2017", levs=c("age"), sortLev="orig")
p1 <- ud_plot(popx, labelvar="age")
p1$uadl
The 65+ age group increased by almost 20% and the 16-39 group actually declined. It is useful to note that the older group was less than half of the size of the 16-39 group in 2011.
There are more examples in the package vignettes.
