Other factors that vary with magnetic fields

Average magnetic fields are associated with various features of a neighbourhood or home. Put simplistically,

  • high-field homes tend to be older, smaller properties, in areas of higher housing density, on busier roads, occupied by families with lower education, socio-economic status and younger children;
  • low-field homes tend to be larger, more spread out, in areas of higher socio-economic status.

Specifically, fields (or wire code classifications) have been reported to be higher in:

  • urban and suburban areas than rural (USA, also seen weakly in UK);
  • homes occupied by poorer families (US);
  • flats and apartments than single-family homes, and terraced houses than detached houses (USA and UK);
  • smaller houses than larger houses (USA);
  • older homes (USA);
  • homes in areas of higher housing density (USA);
  • homes on busier roads (USA, UK);
  • homes with conducting water pipes than with local grounding systems (USA);
  • homes with shorter occupancy (USA)
