Customs District and Contin


This report presents statistics on U.S. exports and
imports by air in U.S. customs district by continent
arrangement. Data have been compiled from Shipper's
Export Declarations (Commerce Form 7525-V) and
import entries during the regular processing of statis-
tical data on foreign trade shipments. The customs
districts shown in this report are those having combined
exports and imports by air valued at $1.5 million or more
during the preceding calendar year. A complete list of
customs districts and ports is presented in Schedule D,
Classification of U.S. Customs Districts and Ports for
U.S. Foreign Trade Statistics, January 1, 1972 edition,
as amended.
Exports
These statistics represent exports of domestic and
foreign merchandise combined and include government
and nongovernment shipments of merchandise by air
from the United States to foreign countries. The
statistics, therefore, include Department of Defense
Military Assistance Program--Grant-Aid shipments,
shipments for economic assistance under the Foreign
Assistance Act, and shipments of agricultural commod-
ities under P.L. 480 (The Agricultura Trade Development
and Assistance Act of 1954, as amended) and related laws.
Shipments to U.S. Armed Forcesanddiplomatic missions
abroad for their own use are not included in the export
statistics. U.S. trade with Puerto Rico and U.S.
possessions and trade between U.S. possessions are not
included in this report, but exports from Puerto Rico to
foreign countries are included as a part of the U.S.
export statistics. Merchandise shipped through the
United States in transit from one foreign country to
another, when documented as such with U.S. Customs,
is excluded. (Foreign merchandise that has entered the
United States as an import and is subsequently reexported
is not treated as in-transit merchandise, and is included


in this report.) The figures in this report exclude ex-
ports of household and personal effects, shipments by
mail and parcel post, and shipments of airplanes under
their own power.
For security reasons, certain commodities are desig-
nated as Special Category commodities, for which
security regulations place restrictions upon the export
information that may be released. The data shown in
this report for individual customs districts and conti-
nents exclude exports of Special Category commodities,
but overall shipping weight and value totals for Special
Category commodities are shown. A list of Special
Category commodities may be obtained from the Bureau
of the Census.
The statistics on exports of domestic and foreign
merchandise to countries other than Canada reflect fully
compiled data for shipments valued $500 and over
combined with estimated data for shipments valued
$251-$499, based on a 50-percent probability sample
of such shipments. For exports to Canada the statistics
reflect fully compiled data for shipments valued $2,000
and over combined with estimated data for shipments
valued $251-$1,999, based on a 10-percent probability
sample of such shipments. Shipping weight and value
data are also estimated for shipments valued under $251.
These estimates are not included in the data shown for
individual customs districts.

Since the export figures shown include estimates
based on a sample of low-valued shipments, they are
subject to some degree of sampling variability. The
table on the following page provides a rough guide to
the general level of sampling variability of value totals,
on a 2 chances out of 3 basis. Usually, the higher value
figures will have the lower percent sampling errors.

The sampling variability of shipping weight figures, in
percentage terms, can be approximated by the percent
sampling variability of value.

Imports

These statistics represent general imports, which are
a combination of imports for immediate consumption


and entries into bonded warehouses. The statistics
include government as well as nongovernment shipments
of merchandise by air from foreign countries to the
United States. However, American goods returned by
the U.S. Armed Forces for their own use are excluded.
U.S. trade with Puerto Rico and with U.S. possessions
and trade between U.S. possessions are not included in
this report, but imports into Puerto Rico from foreign
countries are considered to be U.S. imports and are
included. Merchandise shipped through the United States
in transit from one foreign country to another, when
documented as such through U.S. Customs, is not re-
ported as imports and is excluded from the data shown
in this report. (Foreign merchandise that has entered
the United States as an import and is subsequently re-
exported is not treated as in-transit merchandise and is
included in this report.) Imports of household and
personal effects, imports by mail and parcel post, and
imports of airplanes under their own power are not
included.


The statistics shown for individual customs districts
represent fully compiled data for shipments valued $251
and over. Data for shipments valued under $251, re-
ported on formal and informal entries (informal entries
generally contain items valued under $251), are estimated
from a 1-percent sample. Separate shipping weight and
value estimates for shipments valued under $251 are
shown. The shipping weight data are estimated from the
values on the basis of constants that have been derived
from an observation of the value-weight relationships
in past periods.



Since the statistics showing total value of imports
by all carriers include sample estimates, they are
subject to sampling variability. In general, the higher
value figures will have the lower percent sampling
errors. Value totals of $500,000 and over will generally
have a sampling variability of less than 3 percent; value
totals of under $500,000 will generally have a sampling
variability of less than $50,000.
