I have to find areas on a map where the yearly income is less than a certain threshold, I have all of the data laid out in a table but I am not sure how to process it.
The density for a statistical area can be defined as the ratio of: - (the number people who earn less than x in area1) / (the area of the area1 (in hectare))
Statistical areas are classified as ‘high density’ if they have a density greater than 3 people who earn x or less per hectare.
table is laid out like this: $x to $y amount = 20 people, for example. (so they have all been categorised already)
I have worked out how to create a list of the density by simply doing the division above, but how would I classify these numbers into < 3?
Also, how would I go about ignoring, or not displaying the areas that do not suit my needs (eg. > 3)
