This page contains the data from Appendix 2 of William Nordhaus’ The progress of computing in usable formats.

This data was collected from Appendix 2 of The progress of computing, using Tabula (a program for turning tables in pdfs into other table formats). We have not checked its accuracy beyond a graph of the resulting data looking visually similar to a graph of the original.

Important: we previously noted that this data appears to be orders of magnitude different from other sources, and haven’t had time to look into this discrepancy.

Here is a Google sheet of the data. See ‘Nordhaus via Tabula’ page.
