A Few Words About These United States Population Statistics. All figures listed below for years before 1992 are US Census Bureau figures as per the source files. Where there were an assortment of figures for a specific year, we averaged them. 1992 was an estimate. Years after 1992 are our estimates on a predicted growth rate of 1%, as the average growth rate of all the averaged figures from 1972-1992 was exactly 1.00%. The raw data from which we took these figures is appended as footnote #2. All dates not given are presumed to be July 1, as that is the official date given by the US Census Bureaus, over the years, except where otherwise noted. Dates are for footnoted figures only. Why and How You Should Use These Tables Given the rapid inflation that took place sometimes over the past few decades, you might be aware that if a report said a certain monetary figure was up 10% during one decade, it was prudent to check to see if the figures took the inflationary trends into account to tell you the actual value a figure in one year might represent would actually be less than figures which counted more value in lesser numbers of dollars in the previous decade. Thus you would be wise to consult a table of Price Indices-- such as the file "price10.txt" released in 1993, before your evaluation of such figures is complete. The same is true of population figures, which are going up a certain amount every year, in a very similar manner to those price index figures, only not quite as fast, in most cases. What Started This Report Very recently, there was a report issued on education, which stated something on the order of people in the United States are receiving 10% more of a certain level of education, than they were a decade before. The years and the exact figures have been altered to protect those responsible from embarrassment. For example: let us presume the report stated: Graduation From Grade School was up 5% from 1981 to 1991. You would think from this report that the average kid had 5% greater chances of getting a Grade School Diploma in 91 than in 81. . .but. . .it turns out that it was just the opposite because the population was 1.097352 times larger in 91, than it had been in 1981. . .which is about 10% larger, thus in a "real education" sense, in the same way the monetary reports are given in "real dollars" or "constant dollars," education was actually moving in just the opposite direction, and thus was DOWN about 5% instead of UP about 5% from 1981 to 1991. Remember, these were not from years quoted in the report and the figures were not exactly 5% or 10% respectively, nor the diploma referred to was not a Grade School Diploma, but they are pretty close to being exact, in terms of the percentages and years; much closer than you might expect. ***Here is a footnote explanation of how to be more exact***
