Representatives and direct Taxes shall be apportioned among the several States which may be included within this Union....The actual Enumeration shall be made within three Years after the first Meeting of the Congress of the United States, and within every subsequent Term of ten Years, in such Manner as they shall by Law direct.In other words, tax money coming into the state, and the number of Congressional representatives we have, are based upon numbers gathered every ten years.
