In this exercise we shall be doing two different spatial analysis: one for the Private Residence dedicated to Seniors, and another one for the Private Adult Day Care Facility.  First, we shall begin with Residence Suite for Seniors.

The Residence Suite proposed here is different from general long-term based Old Folks Home.  While a search for suitable Old Folks Home location depend largely on the number of population of adult over 65 (and possibly 80+), and where there is an agglomeration of seniors, that is where a Nursing Home should be located.  For Private Senior Residence it's very different, instead, we are searching for potential senior customers that are independent, active, relatively mobile, needing no care in usual daily routine - but would appreciate a suite that would provide some support services or special design features such as home maker, meals, nursing, adult day care, visitation, etc.

Before we go further, let's have a look at the general distribution of persons 65 years and over in Greater Vancouver.

As we can see, there is a widespread of senior citizens distributed in different areas of Greater Vancouver.  We could also see that this distribution is somewhat relative to population density of the corresponding areas.  Let's move on to the next map.
 
 

The above is as indicated a map of senior citizens that are not living with a family.  This category of seniors include the following groups:

• Persons of 65 of age and above, living alone
• Persons of 65 and above, living with non-relative only (e.g.: Paid Caregiver, full-time Maid, friends)

The third map, which is the one below, derives data from the previous two maps:
 
 

The result is rather pleasing, we see a highest ratio almost in the whole Downtown area, and part of Burnaby and Coquitlam as well.  But still, the result could have been refined further, to find out somewhere within the range of a few locations.  To accomplish this, we will have to make some changes in the display palette that we are using.  Currently, we have been using the default IDRISI32 display palette, which is good for general displaying purpose and preliminary analysis.  For us to isolate a few distinct locations, we shall use ndiv256 palette.
 
 

Clearly, the result is now apparent to us.  The area indicated an agglomeration of Census tracts in West End and Downtown area, including Fairview, Kitsilano, and part of Arbutus and Shaughnessy of in the Northern part of Vancouver west.  There are also a few areas in Port Coquitlam and Port Moody that are considered suitable.
