A majority of people in the North believe it is too soon for the so-called "peacelines" in Belfast to be removed, according to a survey carried out by the US-Ireland Alliance.
The massive fences divide nationalist and loyalist communities in north and west Belfast and are designed to protect householders from sectarian attacks.
More than four fifths of respondents to the US-Ireland Alliance survey said they wanted the fences to be removed, but the vast majority of those say it is still too soon to do so.
Most said they lacked confidence in the ability of the police to maintain order if the walls came down.
