The verdict
Sullivan's Island: among the safest cities in the country.
Based on 0 reported violent incidents in a population of 1,930. At this volume, one additional or one fewer report can shift the rate and letter grade noticeably; small-city crime counts are inherently more volatile year to year than large-city counts, so treat this grade as a data point, not a precise ranking.
Small-count caution
Sullivan's Island reported 0 violent offences in 2024 against a population of 1,930. At this volume one additional or one fewer report moves the per-100,000 rate noticeably, so the figure is better read as a data point than as a precise measurement, and year-to-year swings here are expected.
