Dental RadarWho can realistically use the practice?
Check population, households, age, daytime presence, travel pattern, and the geography that connects those people to the proposed site. No single population count answers all of that.
Evidence before assertions
How to evaluate public and proprietary dental demographic data.
A useful dental site-selection report makes it possible to understand what a number means, which geography it describes, when it applies, and where uncertainty remains. Public and proprietary evidence can both contribute; neither is universally decisive on its own.

This is a vendor-neutral evidence standard, reviewed August 26, 2026. It discusses data types and evaluation methods, not private reports or commercial providers.
Five-minute evidence check
Before a number changes your site decision, write down what would have to be true for it to be useful.
A label such as public, modeled, or proprietary does not answer that question. This worksheet helps you test whether a claim is clear, current enough, geographically relevant, and honest about what it cannot establish.
Fill in this evidence check before you rely on a claim
1. The claim Write the decision-relevant statement in plain language: for example, “this site has enough likely patient demand.” Avoid labels such as “strong” until the underlying claim is specific.
2. Geography and definition Record the boundary, travel time, radius, or ZIP used—and exactly who or what the metric counts. A number for a ZIP may not describe a specific retail center.
3. Source and vintage Note where the figure comes from, whether it is a count, survey estimate, or model, and the collection or release date. “Recent” is not a substitute for a date.
4. Coverage and uncertainty Ask what is missing, estimated, suppressed, or weakly covered. If a survey margin of error, model assumption, or coverage rule exists, keep it with the number.
5. What changes if it is wrong? State the decision consequence. If a reasonable error would reverse the conclusion, the claim needs another source, a broader range, or less weight.
6. Your decision rule Decide in advance what would count as sufficient evidence. That makes it easier to say “not enough evidence yet” without forcing a confident-looking answer.
Four dental claims that need different evidence
Which practices compete for the same patients?
Check the source date, specialty definition, location accuracy, and distance or drive-time rule. A directory count is not automatically the same as accessible competitive pressure.
Can the surrounding market support the practice model?
Use income, housing, employment, and related context as signals with definitions and vintages attached. They describe an area; they do not prove individual coverage, spending, or treatment acceptance.
Is the market actually changing?
Separate observed change from forecast change. Record the time period, base population, boundary, and method before treating a growth figure as a reason to commit.
Compare evidence fairly
Test like with like: use the same address or coordinates, the same boundary, the same definition, and an aligned time period. Keep the raw values alongside any percentage difference, and retain a survey margin of error or model caveat where one applies.
Select cases before you inspect the results. Show agreement and disagreement, not only the examples that favor one method. If two sources disagree, identify the likely difference in geography, definition, timing, or coverage before declaring either one wrong.
Use lifestyle segments as area-level context
Check the scope
Ask what the segment represents.
A lifestyle segment can summarize a modeled area pattern. It is not a verified statement about an individual household, a diagnosis of patient behavior, or proof that a practice model will succeed.
Check the consequence
Use it to ask better questions.
Treat a segment as one reason to inspect local evidence, not as a shortcut around it. If its coverage, definition, or relevance is unclear, do not use it to make a high-stakes site decision.
When “insufficient evidence” is the useful answer
Pause the conclusion when the boundary does not match the site, the source date is too old for the question, the definition is unclear, or a plausible error would change the decision. That is not a failed analysis; it is a clear next step.
Ask for another source, use a range instead of a point estimate, investigate the site in person, or defer the decision until the evidence improves. Then review the report’s source notes and methodology before assigning weight to any market conclusion.
