What is the Ratiolocation Quotient & How does it work?

The Location Quotient (LQ) is a core tool in regional economics, allowing analysts to compare the concentration of a specific industry in a region against the national average. An LQ greater than 1 indicates that the region has a higher-than‑average share of that industry, suggesting a potential competitive advantage.

Mathematically, LQ is expressed as the ratio of two ratios: the share of industry employment in the region divided by the share of the same industry employment nationally. This formulation normalises regional data, making cross‑regional comparisons meaningful even when total employment levels differ dramatically.

Understanding LQ helps planners identify sectors that could drive economic growth, attract investment, or require policy support. It also serves as a baseline for more sophisticated location‑specific analyses such as shift‑share or employment‑trend studies.

\frac{\frac{E_i}{E}}{\frac{N_i}{N}}
LQ = Location Quotient; E_i = regional employment in industry i; E = total regional employment; N_i = national employment in industry i; N = total national employment

Frequently Asked Questions
What is the Location Quotient used for?
The Location Quotient is used to compare the concentration of a specific industry in a region against the national average, helping identify competitive advantages.
How do I calculate the Location Quotient?
Divide the share of industry employment in the region by the share of the same industry employment nationally.
What does a Location Quotient greater than 1 indicate?
A Location Quotient greater than 1 indicates that the region has a higher-than-average share of that industry, suggesting a potential competitive advantage.
Can the Location Quotient be less than 1?
Yes, an LQ less than 1 indicates that the region has a lower-than-average share of that industry compared to the national average.
What industries are typically analyzed using the Location Quotient?
Any industry can be analyzed, but it is commonly used for sectors like manufacturing, technology, and services to identify regional strengths.
How does the Location Quotient differ from other economic indicators?
While other indicators measure overall economic performance, the LQ specifically focuses on industry concentration and comparative advantage within a region.
What are some limitations of using the Location Quotient?
The LQ does not account for factors like cost of living or quality of life, which can affect industry attractiveness beyond employment numbers.
