More than a third of us would not trust anybody on our street with our keys, according to research.

ICM research commissioned by the BBC found that more than one in five believes our neighbourhoods have become less friendly in the last five years.

The study of neighbourliness was aimed at finding out how much people interact with others on their own street.

BBC Breakfast is running a series of films from around Britain looking at three average neighbourhoods to see how things have changed.
