A cost of living index is a broad measurement of the cost of different expenses expected by the average person living in a certain location. Some of the categories tracked include health care costs, transportation, housing, groceries, and more. These numbers are tracked in specific locations to gauge how much it costs to live in a certain area over time.

Another good way to interpret this general number is to ask the question, "How many goods and/or services does a specific amount of money purchase in a given location?" An easy example would be that $100 goes further in Reno, Nevada, than it does in San Francisco, California. The goods and services tracked are need-based, meaning entertainment and other incurred expenses not required to live in a certain area are not tracked.

The main purpose of a cost of living index is to help a person quickly decide if moving from one location to another will increase or decrease quality of life.

Cost of living data are derived from ERI's cost of living surveys and web digitization of public domain records. Data are comprised of health care, transportation, housing, and grocery costs, which are then averaged out across the county. On the graphs above, the "0" represents the country’s average. The percentage can either be lower, expressed by a negative number, or higher than the national average, expressed by a positive number. The important part to remember is the locations are compared to an average of other locations.

Cost of labor may sound like cost of living, but it refers to the price of labor as opposed to the cost to living in a location. Cost of labor refers to all the upfront costs that an employer must pay when hiring work from a particular area. This factors in costs such as the payroll taxes and required benefits when hiring from a particular location. This number is displayed as a percent average higher or lower than the national average.
