If there is one housing trend that has lasted through the last three decades, it’s the continued growth of the American home. Since 1984, the average square footage of a new house in the United States has increased by 1,000 square feet, with the square footage per person almost doubling. Meanwhile, the size of the American household has grown smaller.

We’ve analyzed recently released data from the U.S. Census Bureau to find these home construction trends during the last 30 years.
