Start with the geography you actually serve
Rincon Valley CDP is recorded in Pima County, Arizona. Its 2020–2024 ACS five-year population estimate is 6,512, with a margin of error of 757. Those are measured geographic facts, not evidence that a particular practice area has demand or that residents will contact your firm. A useful attribution setup should preserve the distinction between a Rincon Valley inquiry, a Pima County inquiry and an inquiry from elsewhere in Arizona. If your intake treats every contact as one undifferentiated local lead, you may lose the geographic context needed for budget and service decisions.
Recommended approach
Review how your firm currently records service area, contact location and matter location. Decide which geographic fields are necessary for internal evaluation, then compare them with channel, landing page and outcome. Do not use the population estimate as a substitute for those measurements.
