Features in this iteration of the affordable housing opportunity index (AHOI)
are from census tract level
American Community Survey data. Features have been preprocessed through
a standard normalization procedure, resulting in a range of 0 to 1
for each feature. Depending on the stakeholder group you are a part of,
you may have different opinions about the significance of these features.
Some may matter very little to you, and some may matter a lot. The presence
of some of these features may be desirable to you, and some may not be. Use the preset options to choose
a weighting relevant to the stakeholder group you identify with.
Beyond the presets, this tool and the AHOI have been designed to allow any stakeholder to determine the
weighting most appropriate for them! Changing the weighting is simple.
Features that are desirable should be weighted positively - the larger the
number (with a max of 10), the more significance attributed to it when calculating the score.
The converse is also true: features that are undesirable should be weighted negatively,
and larger negative numbers are weighted more heavily. A weighting of 0
excludes the feature from the index calculation.
The formula to calculate the AHOI score for each feature is simple:
the sum of each normalized value multiplied by the respective weightings you choose!
Floor area ratio (FAR) is a measurement of density. The higher the FAR, the more dense the allowed development. To select only buildings higher than a certain FAR, input a minimum FAR!
