A new Red C poll has found around 74% of people surveyed felt safe around North Dublin City during the day seven years ago, but that number has dropped to 55% as of May this year.
Research also found that in the southside 91% of people felt safe during the day in 2016, while that dropped to 72% this year.
At night, 61% of people feel unsafe on the southside, and 73% on the northside.
Concerns surrounding public safety and a lack of Garda presence have been increasing in recent weeks, following assaults and anti-social behaviour in the city centre.
In response to these concerns, Justice Minister Helen McEntee announced a new funding package at the end of last month, assigning €10 million to increasing Garda visibility in the capital.
Chairperson of The Dublin Business Alliance, Stephen Troy says more funding is needed for areas to feel safer:
"I think there's an awful lot of dereliction around the city. Particularly where we are here on Moore Street. We've a national monument here on Moore Street that has been derelict at the hands of the state for an inordinate amount of time, despite funds being allocated for it's restoration. We all know dereliction and a poor management of a retail district will result in anti-social behaviour".
