ACS 2020–2024 · Cliffside Park borough, New Jersey · Incorporated borough · GEOID 3413570. The survey estimates a population of 25,781 for its five-year window. This is separate from the annual July 2025 population estimate on the city overview.

Median age in Cliffside Park is 41.3 years, with a 90% margin of error of 1.7 years. There are 10,609 households (±593). Age and household distributions show how these totals are composed; they do not establish which neighborhood suits a particular person.

Every count and share is an estimate. “±” is a 90% margin of error (MOE); pp means percentage points. Derived shares use the category count divided by the named universe. Aggregated category MOEs and percentage MOEs are approximate. A margin larger than half its estimate is flagged as low precision. Blank source uncertainty is shown as unavailable, never zero.
