To determine the proportion of those over 50 -
1. The proportion of those over 50s living in rual, suburban, and urban environments;
2. The definition of rural, suburban, and urban; and
3. The top five cities for those over 50.
Ideally, the data will divide the larger group of over 50s into smalller age-based subgroups (50-64 year olds, 65-75 year olds, and over 75s).
