"The LORD spoke to Moses in the Tent of Meeting in the Desert of Sinai on the first day of the second month of the second year after the Israelites came out of Egypt. He said: "Take a census of the whole Israelite community by their clans and families, listing every man by name, one by one. You and Aaron are to number by their divisions all the men in Israel twenty years old or more who are able to serve in the army. One man from each tribe, each the head of his family, is to help you. These are the names of the men who are to assist ..."
Numbers 1:1-5
A census is not a poll.
