How many homeless children are in there in America? This may seem like a simple question to answer. I bet some of you are thinking, “Just look at point-in-time count data,” while others are musing, “That can be answered from annual shelter counts.” Others, still, may be thinking, “The number can be found in a report from the Department of Education.” With so many data sources to choose from, this question isn’t as straightforward as you might assume.
Every time we at the Alliance rely on data, we have to decide which data source will give us the best approximation of the figure we seek. This involves a high level of knowledge and understanding about how each of these data sources collects and compiles numbers. For example, we used five different data sources in our most recent report, The State of Homelessness in America 2015, because no single source captured all the information we needed.
