In the tables below, the first line shows the Base Year: or
"The Year In Question" labeled "YEAR: ####" so if you want a
chart based on 1980 as the base year, you simply search/find
"YEAR: 1980" to find the relevant portions.
Once you have located the table for "YEAR: ####" you can see
comparisons of that year to any other year by looking up the
year you wish to compare to in the left column.
The SAMPLE comparison is 1991, presented below.
You will note a ten year comparison looks like:
year/1991 1991/year Growth%
1981 0.911285 1.097352 0.9031%
This means a 1991 statistic would have to be shrunk to about 91%
of its size to be relevant to a comparable 1981 statistic.
On the other hand, and 1981 statistic would have to be enlarged,
this time by about 10% to be useful in comparison to 1991.
1991 is the latest year for which we have "hard statistics" so a
copy of that year is presented first for you immediate use, with
year back to colonization following, starting with estimates for
2009 when the United States population should reach 300 million.
You may note some fluctuations in these figures, because we used
all reports from the major media and almanacs of the periods our
researchers could find. If you have access to any figures which
do not appear in the footnoted materials, please send them to us
for inclusion in the next edition.
We are also working on a database that will NOT show fluctuation
patterns of this nature, which will be based on massaged figures
presented at later dates by the Census Bureau. These will be an
example of the difference between the figure we can expect on an
entirely "here-and-now" basis, and those which we would probably
not see about today's events until a decade or two have passed.
