13 of the 40 towns surveyed are found to be "cleaner than the European norms".
The Cork town of Fermoy has been found to be the least littered town in Ireland in 2018, as per a new survey conducted by
Irish Business Against Litter.
However, for the second year running, Dublin North Inner City has been ranked 39th out of the 40 towns, this year upgraded from "littered" to "seriously littered".
2018's most littered town is Ballybane - Galway City, replacing last year's most littered town, Galvone - Limerick City.
Navan showed the greatest improvement of any town, rising 20 places in the rankings since last year.
The survey states that litter is worsening in disadvantaged areas, with Conor Horgan of IBAL stating: "We have seen a worsening of litter levels in economically disadvantaged areas, which dominate the lower placings of our rankings. What is often lacking in these areas is a sense of 'pride in place', which in turn reflects an absence of real community.
"In the frenzy to address our housing shortage, we must be mindful of the need to build communities along with houses. Mixed housing is the long-term solution to our urban litter problem."
