Read with context.

Use EJScreen to identify environmental burdens and demographic context, then carry the geography and indicator definition into your interpretation.

Limits to keep in view

Screening indicators support inquiry; they do not establish health causation, legal liability or the experience of every resident.

Connect evidence to action

Choose a question, verify the relevant jurisdiction, and explain the action you are asking someone to take. A source-backed draft is a starting point—not a message sent on your behalf.

Your working notes

Keep the context with the claim.

Write the question first

What are you trying to understand? Identify the population and place before looking for a number that might support your position.

Capture the measure

Record the source title, table or indicator, units, reference period and any stated uncertainty. Preserve the original wording of technical definitions.

Distinguish observation from explanation

A difference between groups can prompt further inquiry. It does not, by itself, identify the cause or establish the effect of a particular policy.
