In the eighth volume of the ‘Historical Statistics of Germany’ statistical overviews on Germany’s mining production for the period from 1850 to 1914 are compiled, especially for the mining product categories bitumen, mineral ores, and mineral salts. (This volume is published within the scientific book series „Sources and investigations on Germany’s Historical Statistics”, ed. by Wolfram Fischer, Franz Irsigler, Karl Heinrich Kaufhold and Hugo Ott; supported by the German Research Foundation (DFG) for several years) Statistical information for the following products were collected: hard coal, brown coal, asphalt (bitumen), mineral oil, graphite, iron ore, zinc ore, lead ore, copper ore, silver ore, quicksilver ore, cobalt ore, nickel ore, bismut ore, tungistic ore, tin ore, manganese ore, antimony ore, arsenic ore, alum ore, pyrite, rock salt or sodium chloride, potash crude salt, and boracite. The investigator tries to cover systematically the statistics of all subareas of the German mining production from official and unofficial data collections. The aim was to offer a versatile usable data manual. Therefore, the collected data were subdivided widely into products and regions. Production volumes, value of mining, the number of factories, and number of employees are recorded statistically. From the year 1912 in the official sources on mining only the total usable mining products are listed, both products destined for sale and products destined for the further processing in the factories. Concerning brown coal and hard coal there are additionally information on the coal-mines’ own consumption. Concerning the producing mines since 1861 there is a differentiation between mines working as ‘main enterprises’ and mines working as subsidiary company. Until 1911 the employees are recorded as average employed persons per day without mining officers (Grubenbeamte). From 1911 the employees are recorded as social insured employees by the end of the year including...
