The ratio of a quantitative value for a defined area to a specified norm. Location quotients are used to describe the relative concentration of an activity or group in one section of a larger area, using the formula:

where
||| Si| | is the value for segment i;|
| | A| | is the value for the total area; and|
| | LQi| | is the location quotient for section i|
| |Thus if the percentage voting Labour in the whole of Great Britain was 43.3 whereas in Scotland it was 49.7, the location quotient for Scotland would be 49.7/43.3 = 1.148
A quotient over 1.0 indicates that the activity is more concentrated in the segment relative to the whole, whereas one less than 1.0 indicates its relative absence there. (RJJ)
