Analysis of information sources in references of the Wikipedia article "Martinet" in English language version.
Based on sales figures from druggists, department stores, wholesalers and artisanal manufacturers, I estimated French production of martinets at 300,000 per year. Taking into account the population of martinable children, the probable duration of use of a family object, I arrived at an approximation of one family in two or three having or having had a martinet.
