This Austrian commemorative stamp was issued in 1979 to mark the 150th anniversary of the Österreichisches Statistisches Zentralamt (Austrian Central Statistical Office). It features a detailed population pyramid graph, illustrating the age structure of the Austrian population divided by gender ("Männlich" for male, "Weiblich" for female) and age groups ("Lebensjahre"). A cherubic figure holding a statistical chart adds a classical artistic element. The stamp's design by O. Zeiller and W. Seidel combines both data visualization and fine engraving—a rare philatelic tribute to demography and public statistics.
