In this graph the base period is switched from our traditional 1951-1980 to 1880-1920 for the reasons given in "A Better Graph", but of course we continue to also produce our graphs with the 1951-1980 base period, as shown below. Data through June 2024 are used for computing the means. Figures in PDF. last modified 2024/07/10)
