METH O DOL O G Y Top 10% is defined as homes with sold prices (or in terms of inventory, list prices), matching or exceeding the 90th percentile sold price for homes sold in 2020 in the specified city. Top 5% is defined as homes with sold prices (or in terms of inventory, list prices), matching or exceeding the 95th percentile sold price for homes sold in 2020 in the specified city. Once these percentiles are determined, these become the thresholds for measuring each month’s data. Data is calculated monthly from various sources to attain the most accurate set of information pertaining to parameters, as seen throughout this report, such as closed sales, active listings, sold prices, sold-price-to-list-price percentages, days on market, and sales ratios. Data is then represented both monthly and yearly throughout the report, using medians, averages, totals, percentages, and ratios. However, unless otherwise specified, statistics typically presented in this report represent both the monthly median and the median of monthly medians of the respective data. The median was calculated by arranging the data in sequential order and selecting the middle number of the set, whether that number be a price, volume, number, percentage, or ratio. To determine the median of the monthly median, monthly medians are totaled and the same method applied as for the monthly figure. Unless otherwise specified, all statistics are based on property sold. Inventory statistics are based on property available at the end of each month. Average Monthly Inventory and Average Monthly Sold statistics are based on the average of monthly property totals for each month. Sales Ratio is based on the ratio of Average Monthly Sold to Average Monthly Inventory. Market Status is an analysis of Sales Ratio and represents market speed and market type: Buyer’s = less than 15%; Balanced = 15% to less than 21%; Seller’s = 21% or greater. If greater than 100%, MLS® data reported previous month’s sales exceeded remaining inventory pulled at the end of the month.
