The location quotient is a simple way of seeing which are the main industries in an area, relative to the wider region. LQ shows the percentage of the local economy characteristic (eg. employment, value add) in a particular industry divided by the percentage of the wider area (region, state, nation) that this industry makes up.
- Where LQ=1, that industry is exactly as prevalent as in the wider region.
- A LQ greater than 1.2 indicates a significant specialisation of the industry in the local area – possibly a key economic strength. Higher numbers mean greater specialisations. Anything over 2 is a major specialisation.
- A LQ between 0.8 and 1.2 means the industry is broadly similar in importance in the local area compared to the comparison region and could be seen as representative.
- An LQ under 0.8 indicates an industry which is more important in the region than the local area, and may represent an economic weakness or opportunity for growth.
LQs should be analysed in combination with the proportional economic share that industry represents. For example, an industry with an LQ of 2 reveals a specialisation but if that industry only represents 3% of the local economy, it may not be significant.
