New Jersey-relative analysis
Among the 680 New Jersey cities PlainCities tracks with reported poverty rate data, Lake Hopatcong ranks #407 - the 39th percentile within the state. This is a different, narrower cut than the nationwide percentiles above: it compares Lake Hopatcong only against its own state's cities, not the full US field.
Ranked by raw value (highest first); a higher rank is not automatically "better" for every measure, see each metric's own context above. This is a comparison within New Jersey only, not a livability score. See the methodology for the source and calculation.
