A REALratio is a proprietary ratio of population to practitioners used to evaluate competition ratios to indicate when a market generally is considered to be saturated. For example, the REALratio for a General Dentist is 2,000.  A ratio higher than 2,000 would indicate the market has potential for an additional practitioner(s). A number below 2,000 indicates the area is already oversaturated and should be evaluated carefully. Each practice specialty has its own REALratio value.
