Answer:
Examining the number of people who have ever experienced homelessness during their lifetime would address the problem of undercounting homeless individuals. Current studies often focus on a point-in-time count, which only captures the number of homeless individuals on a specific day. However, many homeless individuals experience homelessness for short periods of time and may not be counted in point-in-time studies. By examining lifetime experiences of homelessness, researchers may be able to capture a more accurate representation of the extent of homelessness.
