Personal interviews. Extensive
followup of nonrespondents
Including mail questionnaires
for some households.
Adjustments lor
nonrespondents were made
In weighting for respondents.
Item nonresponse resulted in
Imputation or placement In
"don't know" response.
. Estimated CV’s: For fuel
consumed and expenditures,
1.5%; for various fuels,
amounts consumed ranged
from 3.8% for natural gas to
9.0% for LPG.
Household response rate of
91.2%. Non-consumption
data was mostly Imputed for
mail respondents (3.7% of
eligible units). Complete
responses from fuel suppliers
for various fuels ranged from
82.5% for electricity lo 54.6
for fuaf oil and kerosene.
Imputations of energy
consumption for some
master-metered apartments
appear to be greatly
underestimated.

Statistical copies of Shipper's
Export Declarations received
on a dally basis from Customs
ports throughout the country
are subjected to a monthly
processing cycle. They are
fully processed to the extent
they reflect items valued $50
and over, and in the case of
exports to Canada, $2,000
and over. Estimates for
shipments valued at $500 or
less are made, based on
established percentages of
individual country totals.
Estimated CV’s for total value
of exports about .1% and, for
major commodity groupings,
about 1 %. CV’s less than 1 %
for total value over $10
million, less than 2% for
totals between $3 million and
$10 million, and less than
possible errors due to
rounding for value less than
$3 million.
Clerical and complex
computer checks intercept
most processing errors and
minimize otherwise significant
reporting errors; other
nonsampling errors are
caused by undercounting of
exports to Canada due to the
nortreceipt of some Shipper's
Export Declarations.
