Half of people under the age of 35 have never stepped into the home of someone living near them, while less than a third said they would introduce themselves to a new neighbour, a study by Co-op Insurance has found.
Asked on Premier's News Hour why it's important Christians pray for their communities, CEO of the Neighbourhood Prayer Network, Rebekah Brettle, said: "We can actually just make things a little bit better than they are right now and that's got to be something that we should be aiming for."
"If each of us just try to focus on maybe three households on our street, and just prayer for those households and get to know them; we have seen ripple effects on streets where, once people start doing this with just a few neighbours, it does spread throughout the street."
The Co-op Insurance figures also found one in five people have fallen out with a neighbour, while one in ten have been involved in a dispute lasting with a neighbour lasting more than a year.
In a survey of 2,000 adults, it concluded one in ten have also moved home because of an issue such as noise, parking or unruly children.
Suggesting that getting to know a neighbour can help reduce any tension, Rebekah also said the NPN encourages its members to offer practical support such as inviting a lonely person to Christian dinner or collecting a prescription for them.
James Hillon from Co-op Insurance said: "The research shows as a nation we're at risk of losing the community spirit we once prided ourselves on.
"Communities are valuable as they allow people to interact with each other, share experiences and develop valued relationships, without communities we're in danger of living isolated lives.
The report listed showing respect, not being too noisy, keeping gardens presentable and looking after a property when the owner is away are among steps people can take to become better neighbours.
