The value of the dollars used in any particular year would be found in the second column [value compared to 1993]. A dollar in 2010 will be worth about $.51 1993 dollars while a dollar from 1978-9 would be worth about $2.00 now. THE PROJECT GUTENBERG PRICE INDEX FROM 1875 TO 2010 How to use the chart, second set of examples: To remind you that these figures are presented ONLY as an indicator and not as anything approaching reality, here are an additional set of examples from a different report, for several sample years. You can easily see [where we have integrated them below in the 1989 set of figures] that not only are the adjustments sometimes quite high, but that figures from different reports aren't always even remotely close to each other. As an example, while working on these figures I noticed a lack of a period of "double digit inflation" commonly referred to in most all recent reports on these economic trends. I checked this with local sources in the field, and was given the following figures which did include [just barely] some "double digit inflation", but only for a few years of the 70's and early 80's. In short, continue to beware of statistics, and please be advised a bit that while these figures MAY have a certain consistency, within the columns, that there relation to reality is probably far from an intensely accurate reflection of real prices over the century. *** Additional figures from: Economic Report of the President base year 82-84 D-D indicates prices from the end of one year the end of the previous year. . .December to December is the official terminology.
