  • The annual Cost of Living Index (COLI) measures the relative cost of living in six subcategories (housing, utilities, grocery items, transportation, health care, and miscellaneous goods and services) then compiles them into a single overall value.
  • COLI values are relative to a national average value of 100 (100%). For example, Mississippi’s COLI of 87.9 is 12.1% below the average, while Oregon’s 112 is 12% higher than average.
