The U.S. Census Bureau and the Department of Housing and Urban Development have now published their findings for September new residential building permits. The latest reading of 1.241M was a decrease from 1.249M in September and below the Investing.com forecast of 1.278M.

Here is the opening of this morning’s monthly report:

Building Permits

Privately?owned housing units authorized by building permits in September were at a seasonally adjusted annual rate of 1,241,000. This is 0.6 percent (±1.2 percent)* below the revised August rate of 1,249,000 and is 1.0 percent (±1.2 percent)* below the September 2017 rate of 1,254,000. Single?family authorizations in September were at a rate of 851,000; this is 2.9 percent (±1.2 percent) above the revised August figure of 827,000.

Here is the complete historical series, which dates from 1960. Because of the extreme volatility of the monthly data points, a 6-month moving average has been included.

Here is the data with a simple population adjustment. The Census Bureau’s mid-month population estimates show substantial growth in the US population since 1960. Here is a chart of housing starts as a percent of the population. We’ve added a linear regression through the monthly data to highlight the trend.

A Footnote on Volatility

The extreme volatility of this monthly indicator is the rationale for paying more attention to its 6-month moving average than to its noisy monthly change. Over the complete data series, the absolute MoM average percent change is 4.4%. The MoM range minimum is -24.0% and the maximum is 33.9%.
