From what I can understand a bit if the German language but it's just a quick scan over. It seems to be an census for each household. It states where he lives, single. Date of birth, occupation etc what language he speaks. He comes from kargow in Mecklenburg.
Sorry I cannot be exact.
Hi, its a "counting card" for the counting of the German population on 01.12.1900 during the German Reich. The government distributed cards like that to the people of the Reich to count them and make statistics. This is a counting card of Hermann Stьrmer, card no. 5, counting location is Kargow. Also his date of birth, job, religion, etc. This counting card is "Muster B" (right above). On "Muster A" is a instruction, how to fill the counting card. Regards
