Frequently Asked Questions
How is affordability determined in this ranking?
Affordability is based on the Cost of Living Index, which compares average expenses such as housing, food, transportation, and services. Cities are grouped by population size to allow fair comparisons within similar urban categories.
Why does city size affect cost of living?
Larger cities often have higher housing demand, stronger job markets, and greater infrastructure costs, which can increase living expenses. Smaller cities may offer lower housing and daily costs but sometimes fewer economic opportunities.
Should I choose a smaller city to save money?
Not always. While small cities are often more affordable, factors like salary levels, job availability, quality of life, and services should also be considered. This ranking helps you compare affordability within each city size category.
