The document discusses how data can be used to help organizations better understand needs, improve services, and identify underrepresented groups. It provides an example analysis conducted for Amaze to identify neighborhoods and groups underrepresented on their COMPASS register of children with disabilities. The analysis linked postal code data from COMPASS to published datasets on child disability populations and benefits to find which areas had higher than expected numbers and should be targeted. Tools were developed to help other local organizations conduct similar analyses.
