of the $205 billion estimated from the NHA. Of the CE
survey total, $64 billion was spent on health insurance, $34
billion was spent on medical commodities, and $52 billion
was spent on medical services. The medical commodities
total was 65 percent of the NHA estimate, and the medical
services total was 79 percent of the NHA estimate. The ra-
tios for the health insurance estimates are relatively stable
from 1988 through 1991. Moderate variations in the ratios
for the medical commodities total and the medical services
total have occurred over the period.

Current Population Survey. The Bureau of the Census col-
lects income data in the March supplement to the Current
Population Survey (CPS). Using data collected for 1988
through 1990, comparisons are made with CE Interview
survey estimates of total consumer unit income before
taxes and by income component. The CPS aggregate in-
come estimates derive from the mean income of persons
and the number of persons with the specified income.

There are several differences between the CE survey and
the CPS. The CPS collects data in March for the previous
calendar year, while the CE survey collects income data
for the prior 12 months in the second and fifth interviews
of the consumer unit. These interviews may occur any
time during the year. CPS income data which are missing
(because of nonresponse to income questions) are imputed
based on demographic characteristics. By contrast, CE in-
come estimates are for complete income reporters only; in-
come is not imputed in the CE survey. Neither procedure
accounts for underreporting, which is especially prevalent
for property income.

As text table 12 shows, the CE survey total income data
compare well with the CPS for the most part. Total income
for the CE survey averages about 85 to 90 percent of the
CPS. Some difference is expected because the CPS popula-
tion is about 3 percent larger than the CE population. The
low ratios for property income reflect imputations for
missing data in the CPS and underreporting.

interpreting the data

Several factors should be considered when interpreting
the expenditure data, especially when relating averages to
individual circumstances. The data are averages for the to-
tal population—urban and rural. Because not all consum-
er units purchased each item during the survey period, the
average expenditure for an item is generally considerably
lower than the expenditure by those consumer units that
purchased it. The less frequently an item is purchased, the
greater the difference between the average for all consum-

er units and the average of those purchasing the item. For
instance, reference table 1 shows average expenditures for
new cars and trucks of only $1,078, because relatively few
consumer units actually bought a new vehicle. Of course,
the average cost for those who did make the purchase
would be substantially higher than this. For instance, if
about 8 percent of the households reported purchasing a
new car or truck in 1991, the average expenditure on new
cars and trucks for those households would be $13,475.
Even if all consumer units purchased a particular item, an
individual consumer unit may have spent more or less than
the average for that item. Even within a group with similar
characteristics, there may be significant variation. In-
come, family size, age of family members, geographic loca-
tion, and individual tastes and preferences all influence ex-
penditures.

Due to the small sample sizes, take special caution when
using data from the Metropolitan Statistical Area (MSA)
tables (reference tables 19-22). Even though 2 years of data
are used to increase the sample sizes, the average expendi-
tures of the most detailed items may not be reliable because
there may be few reports of expenditures for those items. A
small number of unusually large purchases, or increases or
decreases in the number of expenditures for infrequently
reported items, can cause a large change in the mean from
one year to the next.

Expenditures reported here are the direct out-of-pocket
expenditures. Indirect expenditures, which may be signifi-
cant, may be reflected elsewhere. For example, rental con-
tracts often include utilities. Renters with such contracts
would record no direct expense for utilities and, therefore,
appear to have lower utility expenses. Employers or insur-
ance companies frequently pay other costs. Consumer
units with members whose employers pay for all or part of
their health insurance or life insurance would have lower
direct expenses for these items than those who pay the en-
tire amount themselves.

In addition, use caution in interpreting changes in ex-
penditures over a short time span. Average amounts spent
on different expenditure components may fluctuate from
year to year due to changes in economic conditions. For
example, a decrease in the supply of food products as a re-
sult of poor weather conditions, or a decrease in the oil
supply arising from political events such as an oil embargo
might result in sharp price increases and short-term
changes in expenditure levels. A less volatile measure of
expenditure patterns is the share of total expenditures
spent on major categories of consumption over a period of
several years.
