The population 75 years of age and over is referred to as the "Oldest Old". This group is distinct owing to the noticeable changes in the health status, which are reflected by the different patterns apparent on the map. One pattern that is evident on the layer containing the census divisions and is even more so when observing the census subdivision layer at a greater zoom is that several census divisions containing cities belong to the highest class. See for example Halifax, Fredericton, Saint John, Charlottetown and Regina. The services the elderly need are often located in the larger cities. The census subdivisions indicate that the small towns in the Prairies also have high proportions of this age group. The working-age people are leaving many rural areas to go to towns and cities to seek jobs. As elderly parents need more care they often move closer to their children or move in with them. The cities also provide the facilities and services that this group increasingly needs.
