Futhark, and initiate the boom of medieval Younger Futhark stones (with some 6,000 surviving examples). As of 2021, one inscription was found in a settlement associated with Slavs. Elder Futhark inscriptions were rare, with very few active literati, in relation to the total population, at any time, so that knowledge of the runes was probably an actual "secret" throughout the Migration period. Of 366 lances excavated at Illerup, only 2 bore inscriptions. A similar ratio is estimated for Alemannia, with an estimated 170 excavated graves to every inscription found. Estimates of the total number of inscriptions produced are based on the "minimal runological estimate" of 40,000 (ten individuals making ten inscriptions per year for four centuries). The actual number was probably considerably higher. The 80 known Southern inscriptions are from some 100,000 known graves. With an estimated total of 50,000,000 graves (based on population density estimates), some 80,000 inscriptions would have been produced in total in the Merovingian South alone (and maybe close to 400,000 in total, so that of the order of 0.1% of the corpus has come down to us), and estimates a population of several hundred active literati throughout the period, with as many as 1,600 during the Alamannic "runic boom" of the 6th century.
