Now, absolute accuracy is
usually theoretical, even when measuring objects scientifically,
however to dismiss the importance of trying to reach results as accurately as
we can because of this, would be nihilistic. Instead, we measure as accurately
as we can, and we acknowledge our limitations, up front, before we even start
to measure. If we properly minimize our limitations, as much as we can, we can
reach valid numbers.
Indeed, this is why we have
always been very public about the measure of accuracy that can be achieved, the
need to improve our count, and how we have done just that since 2015. This is
also why more than a fifth of the State of the Homeless Address,
this past March, was devoted to the intricacies of scientific
mapping and resulting count methodology for
our annual Homeless Count.
So, how many people do
experience homelessness in Dallas ?
In our playbook, we talk about two
important numbers we always keep in mind, “the number of those experiencing
homelessness at any one time, about 3,800 in our last count, and
the number of those who experience homelessness throughout the year. The
annual Homeless Count, conducted every
year around the same time, gives us the first number, and throughout the year,
we use our Homeless Management Information System (HMIS) to track the
second number, which is around 9,750. Obviously, the second number is
always going to be larger than the first one, since the second number
includes anyone who was homeless throughout the 365 days of the year.
It is important to keep in
mind the difference between the two numbers, because we have seen some
confusion in this area. In fact, a claim that comes up again and again is that
there are about 10,000 people in Dallas and Collin Counties
who are experiencing homelessness, in the present tense. Though we are not
totally sure where that number came from, those who originated it, were
probably confusing the two very different numbers. There simply are not
10,000 people experiencing homelessness, currently, in our two counties. The data,
i.e. factual reality, does not support such a number.
