Jobless Claims Up Slightly, But 4-Week Moving Average At New Interim Low

by: Doug Short

The Unemployment Insurance Weekly Claims Report was released this morning for last week. The 336,000 new claims number was a 13,000 increase from the previous week's 323,000 (an upward revision from 320,000). The less volatile and closely watched four-week moving average, which is usually a better indicator of the recent trend, fell by 2,250 to 330,500, the lowest level since November 17, 2007.

Here is the opening of the official statement from the Department of Labor:

In the week ending August 17, the advance figure for seasonally adjusted initial claims was 336,000, an increase of 13,000 from the previous week's revised figure of 323,000. The 4-week moving average was 330,500, a decrease of 2,250 from the previous week's revised average of 332,750.

The advance seasonally adjusted insured unemployment rate was 2.3 percent for the week ending August 10, unchanged from the prior week's unrevised rate. The advance number for seasonally adjusted insured unemployment during the week ending August 10 was 2,999,000, an increase of 29,000 from the preceding week's revised level of 2,970,000. The 4-week moving average was 2,985,750, a decrease of 1,000 from the preceding week's revised average of 2,986,750.

Today's seasonally adjusted number was above the Investing.com forecast of 330K.

Here is a close look at the data over the past few years (with a callout for the past year), which gives a clearer sense of the overall trend in relation to the last recession and the trend in recent weeks.

As we can see, there's a good bit of volatility in this indicator, which is why the 4-week moving average (the highlighted number) is a more useful number than the weekly data. Here is the complete data series.

Occasionally I see articles critical of seasonal adjustment, especially when the non-adjusted number better suits the author's bias. But a comparison of these two charts clearly shows extreme volatility of the non-adjusted data, and the 4-week MA gives an indication of the recurring pattern of seasonal change in the second chart (note, for example, those regular January spikes).

Because of the extreme volatility of the non-adjusted weekly data, a 52-week moving average gives a better sense of the secular trends. I've now added a linear regression through the data. We can see that this metric continues to fall below the long-term trend stretching back to 1968.

A Four-Year Comparison

Here is an overlay of the past three calendar years and the beginning of 2013 using the 4-week moving average. The purpose is to show the relative annual slope of improvement since the peak in the spring of 2009. The latest year was off to an excellent start. It then oscillated a bit, stalled for about nine weeks, but since the July 9th report, the trend has been in the right direction. The current reading, as mentioned at the outset, is the lowest since before the last recession.
