FRED, the data-rich economic research site from the St. Louis Fed, says the housing market has been a hot topic of conversation over the past two years and their new “Hotness” score illustrates that point with the help of data from Realtor.com. They say their new “hotness” index aims to reflect “fast moving supply and rising demand” conditions and does not necessarily represent high or rising housing prices. The interactive, color-coded map below shows selected counties using a scale of cool blue-greens: darker equals hotter. As of the current data, two of the three hottest counties are less than an hour’s drive from each other in central Ohio. Click on the map to make it interacive.
