Each Real Estate Sentiment score is derived through statistical diffusion weighted to consider response intensity. A sentiment score of zero (0) in any category, reflects a breakeven point at which equal levels of optimism and pessimism among the population have been measured relative to the overall market, or buying or selling real estate. Scores can range from an absolute low of -100 to a high of 100 but scores below -50 or above +50 are both rare and extreme. If 100 percent of people describe the overall market or either buying or selling as greatly improved the sentiment score would equal 100. Conversely, universal extreme pessimism would score -100. Scores measure and reflect the collective sentiment of residents of New York State.
