According to the U.S. Federal Reserve, the size of American yards has been decreasing in size since the 1800s. While there have been some generations where yards have increased in size proportional to houses (namely 1985 through 1990), most properties have decreased in size. The rate at which yards decrease is also proportional to the increase in the size of homes, so, in short, our homes are taking up the space that used to go to yards. Furthermore, home lot sizes have also been decreasing, hitting record lows in 2019.
