Retail sales slumped according to US Census and well under expectations. Our analysis again slightly disagrees – but the unadjusted data in this series declined marginally (driven to a large part by backward revision). Overall the rolling averages are yielding a rather flat growth line showing there is too much noise in the monthly figures.
- unadjusted sales rate of growth accelerated 1.6% month-over-month, and up 4.6% year-over-year.
- unadjusted sales 3 month rolling year-over-year average growth decelerated 0.4% month-over-month to 4.2% year-over-year.

- unadjusted sales (but inflation adjusted) up 4.1% year-over-year
- backward revisions were mixed but did make current month seem stronger;
- this is an advance report. Please see caveats below showing variations between the advance report and the “final”.
- in the seasonally adjusted data – almost all areas were strong this month for retail sales growth, with only miscellaneous retailers and gasoline stations being the headwinds month-over-month.
- seasonally adjusted sales decreased 0.9% month-over-month, up 2.6% year-over-year
- the market was expecting:
|seasonally adjusted||Consensus Range||Consensus||Actual|
|Retail Sales – M/M change||-0.4 % to 0.4 %||-0.1%||-0.9%|
|Retail Sales less autos – M/M change||-0.4 % to 0.5 %||-0.1%||-1.0%|
|Less Autos & Gas – M/M Change||0.4 % to 0.8 %||+0.6%||-0.3%|

Retail sales per capita seems to be in a long term downtrend (but short term trends vary depending on periods selected – see graph below).

From the U.S. Census Bureau press release:
The U.S. Census Bureau announced today that advance estimates of U.S. retail and food services sales for December, adjusted for seasonal variation and holiday and trading-day differences, but not for price changes, were $442.9 billion, a decrease of 0.9 percent (±0.5%) from the previous month, but up 3.2 percent (±0.9%) above December 2013. Total sales for the 12 months of 2014 were up 4.0 percent (±0.6%) from 2013. Total sales for the October through December 2014 period were up 4.1 percent (±0.7%) from the same period a year ago. The October to November 2014 percent change was revised from +0.7 percent (±0.5%) to +0.4 percent (±0.1%).
Retail trade sales were down 1.1 percent (±0.5%) from November 2014, but 2.6 percent (±0.7%) above last year. Auto and other motor vehicle dealers were up 9.8 percent (±3.0%) from December 2013 and food services and drinking places were up 8.2 percent (±3.3%) from last year.

The differences between the headlines and Econintersect are due to different approaches to seasonal adjustment (see caveats at the end of this post). Long and medium term trends always agree comparing the adjusted to the unadjusted data – it is the short term trends and month-over-month change where the conflict occurs.

Declines of short duration often occur in the seasonally adjusted series without a recession resulting.

Using employment as a gauge to check growth, employment in retail has been growing – but the rate of growth recently has been slowly declining.

And finally, as retail sales can be a component of determining a recession start date, the zero line of the graph below could be an indicator a recession was underway (or about to begin).

Caveats On Advance Retail Sales
This data release is based on estimates. However, the estimates have proven to be fairly accurate although tend to miss at economic turning points. Therefore up to three months are subject to backward revisions, although normally slight, can sometimes be modest.
The data in this series is not inflation adjusted – and Econintersect adjusts using CPI less shelter CUSR0000SA0L2. The St. Louis Fed also inflation adjusts the Census seasonally adjusted data. The last two recessions began as the inflation adjusted retail sales crossed the zero growth line.

As in most US Census reports, Econintersect does not agree with the seasonal adjustment methodology used and provides an alternate analysis. The issue is that the exceptionally large recession and subsequent economic roller coaster has caused data distortions that become exaggerated when the seasonal adjustment methodology uses more than one year’s worth of data. Further, Econintersect believes there is a New Normal seasonality. Using data prior to the end of the recession for seasonal analysis could provide the wrong conclusion.
The impact of the monthly retail sales data on GDP is not straight forward. Real GDP (of which the consumer is over 60%) is adjusted for inflation. Further, GDP is an analysis of quarter-over-quarter or year-over-year growth, while retail sales is a monthly data series.
Econintersect determines the month-over-month change by subtracting the current month’s year-over-year change from the previous month’s year-over-year change. This is the best of the bad options available to determine month-over-month trends – as the preferred methodology would be to use multi-year data (but the New Normal effects and the Great Recession distort historical data).
From Econintersect contributor Doug Short:
Those of us who routinely track this series know that the Advance Estimate will be followed by a second estimate next month and a third estimate the month after. How big are those revisions? Are they big enough to warrant skepticism about the Advance Estimate? Here is a visualization of the cumulative change from the first to third estimates from January 2007 through March 2014, the most recent month for which we have three data points.
