Description
Divide localSector by positive localTotal and positive referenceSector by referenceTotal, validating sector counts within totals.
Population indicators depend on compatible boundaries, time periods, counted groups, and denominator choices. A share or density can change when exclusions or daytime populations change, even without arithmetic error.
Divide localSector by positive localTotal and positive referenceSector by referenceTotal, validating sector counts within totals.
When to use this tool
Use Location Quotient One Employment Cell when you need one transparent population-accounting component.
How to use the tool and how it works
- Enter localSector, localTotal, referenceSector, referenceTotal. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read localShare, referenceShare, quotient. Use the output convention below.
Divide localSector by positive localTotal and positive referenceSector by referenceTotal, validating sector counts within totals. Return localShare/referenceShare as quotient.1

}Limitations and assumptions
- The reference sector cannot be zero; compatible sector and geographic definitions are assumed and concentration does not establish productivity or specialization causes.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review source definitions, geography, temporal alignment, and uncertainty before making a demographic or service-access conclusion.
