How we compute this

We re-derive these figures from Census ACS 5-year data (table C16001) at the ZIP/ZCTA level: the national share is the sum of Spanish speakers who speak English less than "very well" divided by the population age 5 and older. The figure is computed live, not carried as a stored constant.

Federal Consumer Confidence Report rules do not require water-quality reports to be translated. California requires translation once Spanish limited-English speakers reach 10% of a service area; we report how many ZIP codes meet that same benchmark nationally.

The ACS is a multi-year survey; the vintage is shown in the as-of label. Each ZIP code links to its per-ZIP report.
