While the U.S. housing market has largely recovered from the effects of the subprime mortgage crisis, homes are being built at barely half the rate they were in the early 2000s. The history of the U.S. housing market has been one marked by periods of rampant building and of lulls, even as the population has expanded relatively steadily.

U.S. housing starts in February 2019 clocked in at a seasonally-adjusted annual rate of 1.2 million. The rate is less than half the 2.5 million housing starts in 1974 — a time when there were 100 million fewer people living in the country.

The American housing market has not only been through substantial fluctuations in the number of housing units built, but also by changes in the size of homes. Changing family size, rising incomes, and suburban expansion have all led to changes in the size of the typical single-family home.

To determine how the size of homes has changed over the past century, 24/7 Wall St. determined the size of a newly constructed single-family house between 1920 and 2017 by reviewing official U.S. Census figures and providing our own estimates for years the Census did not release numbers.

Methodology

To determine the average size of a newly constructed single-family home between 1971 and 2017, 24/7 Wall St. used survey data from the Census Bureau’s American Housing Survey. For the years 1963 and 1970 we used data from the Census Bureau’s U.S. Department of Housing and Urban Development’s 1969 “Characteristics of New One-Family Homes” construction report. For the years 1940, 1950, and 1954 to 1956, we used the Bureau of Labor Statistics New Housing and its Materials 1940-56 report. For all other years, we estimated the average size of a newly constructed home using construction data on residential housing starts and total residential floor space constructed in a given year from the Census Bureau’s annual “Statistical Abstracts of the United States” and its “Historical Statistics of the United States, Colonial Times to 1970” report. We took the quotient of total residential floor space and total residential housing starts and made adjustments to account for the inclusion of multi-family housing units and exclusion of various states in the national tally of total floor space constructed. We also adjusted housing starts to better approximate housing completions. Average household size also came from the Census Bureau. GDP per capita figures for years 1929 to 2017 are from the Bureau of Economic Analysis. GDP per capita figures for years 1920 to 1928, which were not available from the BEA, came from estimates by the Maddison Project.
