CUSTOMS DISTRICT BY CONTINENT


COVERAGE


This report presents U.S. export and import statis-
tics by air in U.S. Customs district by continent
arrangement. Only those districts are shown whose
combined exports and imports by air were valued at
2 million dollars or more for calendar year 1964.
Exports
These statistics represent exports of domestic and
foreign merchandise combined and include government
as well as 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 snip-
ments, Mutual Security Program economic assistance
shipments, and shipments of agricultural commodi-
ties under P. L. 480 (The Trade Development and
Assistance Act of 1954, as amended) and related
laws. Shipments to U.S. armed forces and diplomatic
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 through U.S. Customs, is excluded.
(Foreign merchandise which has entered the United
States as an import and is subsequently reexported
is not treated as intransit merchandise, and is
included in this report.) The figures in this re-
port exclude exports of household and personal ef-
fects, shipments by mail and parcel post, and ship-
ments of airplanes under their own power.

The statistics shown for exports to Canada represent
fully compiled data for shipments individually valued
$2,000 and over combined with estimated data for
shipments valued $100-$1,999 based on a 10-percent
sample of such shipments. The statistics shown for
exports to countries other than Canada represent
fully compiled datafor shipments individually valued
$500 and over combined with estimated data for ship-
ments valued $100-$499 based on a 50-percent sample
of such shipments. In addition to these data, esti-
mated data for shipments valued under $100 based on
a lO-percent sample of such shipments are also included


in the figures shown in the "Total" columns intable 1.
These estimates for shipments valued under $100
are not included in the other figures in the table.
Since the export figures shown include estimates
based on a sample of low-valued shipments, they are
subject to some degree of sampling variability.
A rough guide to the general level of sampling
variability (on a 2 changes out of 3 basis)
of value totals shown is given below. Usually the
higher value figures will have the lower percent
sampling errors. Detailed information on the sam-
pling variability of individual figures is avail-
able upon request.


Value totals for
"Total" and "North
America" of:


$1,000,000 and over
$500,000-$1,000,000
$100,000-$500,000
$20,000-$100,000
Cells of under $20,000



Value totals for
continents of South
America, Europe,
Asia, Australia and
Oceania, and Africa of:

$300,000 and over
$100,000-$300,000


$20,000-$100,000


Under $20,000

.15 .40 .45 .55

Are likely to have sampling
variability from $10,000
to $20,000

Are likely to have sampling
variability of:




Less than 2%

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

Imports

These statistics represent general imports which
are a combination of imports for immediate consump-
tion and entries into bonded warehouses. The sta-
tistics include government as well as nongovernment
shipments of merchandise by air from foreign coun-
tries 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-
pod a ported as imports and is excluded from the data
shown in this report. (Foreign merchandise which
has entered the United States as an import and is
subsequently reexported is not treated as intransit
merchandise, and is included in this report.) Im-
ports of household and personal effects, imports by
mail and parcel post, and imports of airplanes under
their own power are not included.

The airborne general import statistics reflect
fully compiled data for formal entry shipments val-
ued at $100 and over combined with estimated data
for shipments reported on informal entries valued
at $250 or less based upon a 10-percent sample of
such shipments. These combined data are shown in
the "Total" column for the value data in table 2 of
this report. The continent and district by conti-
nent value totals shown in the table include data
for formal entries valued at $100 and over but ex-
clude the estimated dollar value for shipments re-
ported on informal entries valued $250 or less.


The shipping weight information excludes shipping
weight data for informal entries since this infor-
mation is not required to be shown on such entries.
Some rough indication as to the volume of shipping
weight represented by informal entries may be ob-
tained by reference to the air export statistics
where low-valued shipments (under $100) are approx-
imately 2 to 3 percent of the air export value and
from 10 to 12 percent of the air export shipping
weight. Import shipments by air reported on formal
entries valued at less than $100 are entirely ex-
cluded from the air import statistics. These under-
$100 formal imports shipments amount to less than
1 percent of the total air import value and shipping
weight.

As noted above, the value figures for total air
imports by Customs district include estimates of
informal entries ($250 or less) based on a 10-percent
sample of such entries. They are, therefore, subject
to sampling variability. In general, the higher
value figures will have the lower percent sampling
errors. The following table gives a rough guide to
the sampling variability of Customs district totals.
More detailed information on the sampling variability
of individual figures is available on request.


Value totals of:



$500,000 and over

$100,000 $500,000

$20,000 $100,000

Under $20,000


Are likely to have
sampling variability
limits of:

Less than 1%

1% to 5%

5% to 15%

$1,000 to $2,000


The Customs district value and shipping weight
totals shown include a small amount of shipments
which could not be distributed by continent.
