age group 24, the housing quality index had a
decrease in age group 24.
It is important to point out the inconveniences
of the lower number of units at some age levels.
For instance, age groups 15 and 25 had less than
five units to be observed. These were the groups
with the greatest difference between the two indices (Table 9.2).
In terms of the results for both separate owneroccupied and rental units, Tables 9.3 and 9.4
show all the values, taking into account occupancy. As regards owner-occupied units, the
results from the value ratio index and the housing
quality index are different, 36% and 19%, respectively. In the case of rental units, the results are
almost identical (value ratio index = 29% and
housing quality index = 32%). Again, some age
groups present less than five housing units (age
groups 17, 18, and 19 in the case of owneroccupied and 15, 17, and 25 in the case of rental).
Tables 9.5, 9.6, and 9.7 present the number
and corresponding proportions of units that are
adequate or in need of rehabilitation by type of
housing units. Regarding single-family residential units, both indices detected the same proportion of units in need of rehabilitation (26%). Only
age groups 17 and 25 had less than 5 units total.
When compared to the proportions for singlefamily residential units, for duplexes and triplexes, the total number of units in need of
