My project seems to suggest that the GVRD is considered a fairly healthy place to live. The main areas where people live received high health index scores and places where population was sparse received low scores. As long as these areas with lower scores do not become residential, the people of the GVRD seem to live in healthy environments.
Of course this is just one approach on defining the level of health of the environment. Others may consider my factors to be unimportant, or may have felt I left out other factors that are more imperative to environmental health. Some sources of error could have been from the assumptions I made or the factor weighting of my multiple MCE maps. I definitely feel like if I had lowered the maximum walking limit to something like 800m, I would have had much more deviation of the MCE maps. There are many reasons why some people may prefer to walk less or more. It could all depend on their age, the current weather or the reliabilty of the transit system. My decision to choose 1600m as the maximum walking distance definitely played a huge role in my end results. I believe a change in the maximum walking distance would change the end results more drastically than changing the weighting factors. As explained at the end of 'Results 1'; all the factors are likely to be close to each other, so changing the factors would not change the end results. Another important assumption made was that people would naturally choose the closest source of food. Of course this is not always with everybody, I know personally I would take a longer trip just to get fast food even if there is a nearby grocery store. This assumption is also open to debate and very subjective. There are other areas where error could have been brought into my model; but I believe the choice of the factors, maximum walking distance, and the assumption that people choose where they eat according to distance were the main sources of error.
Lastly, I think it would have been more informative to do additional analyses after the creation of the MCE maps. I personally only looked where children, elderly, and lower household income families lived. Just by looking at these three groups would not be enough to conclude anything. Possibly analyzing unemployment rates, education level, density of ethnicities may answer some questions. Unfortunately with the time frame I was only able to look at these three groups. Clearly, additional analyses may result in interesting outcomes something I may be interested in doing in the future.
