Initial Jobless Claims Improve Slightly Before Big Unemployment Data

The Department of Labor’s Unemployment Insurance Weekly Claims Report was released this morning for last week. Today’s number keeps us above the 400K level, where it has been for 20 of the last 21 weeks. The less volatile and closely watched four-week moving average is now at 19 consecutive weeks above 400K and has been rising for the past two weeks. Here is the official statement from the Department of Labor:

n the week ending August 27, the advance figure for seasonally adjusted initial claims was 409,000, a decrease of 12,000 from the previous week’s revised figure of 421,000. The 4-week moving average was 410,250, an increase of 1,750 from the previous week’s revised average of 408,500.

The advance seasonally adjusted insured unemployment rate was 3.0 percent for the week ending August 20, unchanged from the prior week’s revised rate of 3.0 percent.

The advance number for seasonally adjusted insured unemployment during the week ending August 20 was 3,735,000, a decrease of 18,000 from the preceding week’s revised level of 3,753,000. The 4-week moving average was 3,726,000, a decrease of 3,250 from the preceding week’s revised average of 3,729,250.

Today’s number was slightly worse than the Briefing.com consensus estimate of 407,000 claims.

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

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 long-term trends.
