Start with the Southwick service area, not a population assumption
That exact relationship matters when you define service-area rules, reporting labels and intake questions. Those decisions should come from your existing inquiry records, current service area and operating hours.
Recommended approach
On a Bosseo review, define Southwick as one geographic value in your intake and reporting structure. Decide whether nearby communities, Hampden County and Massachusetts-wide matters should follow the same path or different paths.
