In more recent times, a much larger number of gated communities
has rapidly developed in various regions throughout the world. In
2000, eight million U.S. residents lived in gated communities. In
many parts of the world, buyers are expressing a preference for
gated communities. While many see living in a gated community as
offering increased security, they are not impenetrable. Walls are
frequently low enough for someone to climb over them. Gates can be
bypassed by tailgating cars and, for those willing, access through
the sewer system. Pedestrians can enter by means of pedestrian
gates, which are generally unlocked.
