The second column of the spreadsheet on this thread is an estimate going back to 1900. Some of this data is linearly extrapolated because the article I used originally (ref provided) only gave data for "0" years (1900,1910, 1920 etc.)
Before then, I don't know. If you find a reference, please post it so we can all use it.
