Straight-line distance can hide the journey
A clinic one mile away may require crossing a highway or taking two buses. Another farther away may be reachable on a direct route. A circle drawn around a point does not describe every travel mode.
The relevant journey also includes returning home and fitting the visit around other responsibilities.
Add a service layer to the location layer
| Map information | Additional question |
|---|---|
| Facility address | Is the relevant service offered there? |
| Travel time | At what time and by which mode? |
| Opening hours | Are appointments actually available? |
| Service population | Who is eligible and able to pay? |
Ask residents to interpret apparent coverage
Local experience can explain why a mapped resource is rarely used or why a service beyond the boundary matters. Validate the directory as well; a listed location may have moved or changed services.
Use the map to identify questions and patterns, not to declare that nearby residents have no access problem. A more complete assessment connects geographic availability with the practical conditions required to obtain care. That distinction can change the response from building another facility to addressing a different barrier.
