Start with what was measured
A county estimate describes a defined population in a defined place. It cannot become a neighborhood measurement simply because a user searched for a neighborhood. The interface needs to preserve the measurement geography.
Keep time in view
A dataset’s release date and the years underlying its measurements answer different questions. Display both. A recently published release may incorporate observations from earlier years.
Carry uncertainty into comparisons
Point estimates can look more decisive than the evidence permits. Display confidence intervals alongside the values. A difference between two estimates is not, by itself, a test of statistical significance or evidence of causation.
Make inspection part of the experience
In the CB-CAP public preview, a reader can select a county, compare the same measure within a state and trace the selected estimate to its source context. Missing values remain unavailable rather than becoming zero.
