One of the most remarkable aspects of the manufactured housing industry is its rapid evolution over its short history: From 1974 to 1993, year-round occupied manufactured units increased by an average of 2.2% per year, while all other year-round occupied homes increased only 1.5% per year.

The major growth of the manufactured housing stock has occurred between 1985 and 2000, when manufactured housing increased at 2.2% annually, while growth in the rest of the inventory was only 0.7% each year.
