COMPOSITE INDEXES OF LEADING, COINCIDENT, AND LAGGING
INDICATORS: SEPTEMBER 1980
The composite index o f leading ind ic ato r s increased 2 .4 percent in
September to a l e v e l o f 133.6 (1967=100), according to preliminary data
rele as ed today by the Bureau o f Economic A na lys is , U.S.. Department of
Commerce. On the bas is o f more complete data, the August index le vel was
revised to 130.5, which i s 1.7 percent above the revise d July l e v e l of
128.3. Change in t o t a l li q u id a s s e t s was the major contributor to the
August r e v i s i o n .
Eight of ten ind ic at or s a v a i l a b l e for September contributed to the
increase in the index: average workweek, l a y o f f r a t e , vendor performance
( i . e . , companies r ec e iv in g slower d e l i v e r i e s from vendors), change in
to t a l li q u i d a s s e t s , change in s e n s i t i v e raw materials pric es (Producer
Price Index), stock p r i c e s , new orders in 1972 d o l l a r s , and building
permits. Layoff rate contributed the g r e a t e s t increase.
Two o f ten declined: co ntracts and orders for plant and equipment
in 1972 d o ll a r s and money supply in 1972 d o l l a r s . Money supply in 1972
d o ll a r s contributed the g r e a t e s t d e c li n e .
The composite index o f c o in c id e nt i n d i c a t o r s , which i s a monthly
approximation o f aggregate economic a c t i v i t y , increased 0.2 percent in
September to a le v e l o f 136.1 (1967=100). On the bas is of more complete
data, the August index le v e l was revise d to 135.8, which i s 0.1 percent
below the revise d July le v el o f 136.0.
The composite index o f lagging in d ic ato r s increased 3.3 percent in
September to a le ve T -o f 166.9 (1967=100). On the bas is of more complete
data, the August index le v el was revise d to 161.5, which i s 1.4 percent
below the revised July le v el o f 163.8.

- 2 -

The leading index i s designed to pr ed ic t monthly movements in
aggregate economic a c t i v i t y , which i s approximated by the coinc iden t
index. The lagging index i s expected to move, a f t e r a time l a g , in
the same d ir e c t io n as the co in c id e nt index and thus to confirm the
movements in the c oin ci den t index. These concepts are explained more
f u l l y in the Handbook o f C yc lica l In d ic a to r s , a supplement to B usiness
C onditions D igest (BCD)3 a v a i l a b l e from the Superintendent o f Documents
at the price o f $4.00.
More data on the composite indexes, as well as other important
measures o f economic a c t i v i t y , appear in BCD. I t i s a v a il a b le from
