ACS percentages are derived point estimates. No ratio MOE is calculated for the derived shares; the published category estimate/MOE and denominator are shown above.

B25034’s aggregate MOE is an approximation from component MOEs, not a separately published table value.

Scope: NOAA HDD65/CDD65 is one station-based climate evidence family; the Census tables form one ACS evidence family. ACS values describe reported housing-unit measures for the named statistical geography, not an individual property.
