Population over time
2 figuresIslip fell from 18,689 to 18,418 between 2010 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate, and an estimate published within five years of a census is left out. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

| November 2021 | Tornado (EF0) | East Islip | $500,000 | Survey team confirmed an EF0 tornado in East Islip, NY, a narrow tornado of 50 yard width likely touched down at the southwestern end of Hollins Lane, and then continued northeast over Brushwood Court, Bayview Avenue, and Josephine Lane, and then finally over Kay Court, before lifting over the John F. Kennedy Elementary School sport fields. A few dozen large oak, maple, and pine trees were uprooted and laying in east or northeast direction. Several trees were also snapped at the trunk or had large branches sheared off along this path. In addition, minor roof and siding damage was observed for several houses, as well as leaf splater on south and east sides of several houses. This tornadic circulation was likely on the northwest side of a 400 yd. swath of 65 to 75 mph west to southwest straight line winds causing isolated large trees to be uprooted and several large limbs broken.||As mentioned, the tornado likely lifted over the John F. Kennedy Elementary School sport fields, becoming a funnel cloud. This funnel cloud may have briefly touched down as a weak tornado in the Frog Lane and Jade Street area of Oakdale, resulting in a very large, but partially rotted oak tree to topple onto and destroy a home. The funnel cloud was videotaped by the public, looking southwest from the Old Navy Department store on Johnson Avenue (just north of Sunrise Highway), but no further damage was noted with this storm.||Based on radar velocity signatures and damage orientation in relation to the general northeast motion of the parent storm, this was determined to be tornado damage, with degree of damage indicating EF0 damage. |
