Double digit percentages for white, black, Hispanic and Asian populations

Possibly in Jersey City.

Never mind precincts, the entire city of Jersey City is 21.5% White, 23.9% Black, 27.6% Hispanic, and 24.9% Asian. Hell, even Hudson County even fits at 30.8% White, 11.2% Black, 42.2% Hispanic, and 13.2% Asian.

Just because a city at large meets the criteria doesn't mean necessarily any precincts in it do. You could theoretically have a very segregated city with large populations of all four groups but concentrated all in different areas. For example I doubt there's any precinct in Chicago or Milwaukee that is very close to the city at large's demographic makeup.

Point taken. Here's a look at Jersey City, then. Green precincts qualify, red precints don't.
