Over a third of people in Jersey who took part in a survey feel unsafe in St Helier town centre after dark.
A States report has also found 13% of people do not go to town at night because of concerns for their safety.
A strategy to make the island safer came into force five years ago aiming to prevent the harm caused by crime.
The report shows recorded crime in Jersey is at its lowest in five years with nearly 49 crimes recorded for every 1,000 people.
The report was commissioned as part of the 'Building a Safer Society Strategy'.
It said there was a need for tackling anti social behaviour and looking at ways night time businesses make their money.
