Article 2, Section 2, Clause 2.3 of the United States Constitution states in part:
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.*
Here's a little public service announcement from the Don't Do That team: People, don't forget to send in your census form! Mail it in by tomorrow! If you like where you live at all, or you're planning to live there for any period of time, or you have friends and family who are planning to live there for any period of time, it is very important that you fill in the form. Getting them the numbers of how many people live in your area will bring (or take away) a lot of important things to your neighborhood, city, county, and state, including public transportation, good roads, increased funding for the schools, additional representation in Congress, and all sorts of other good stuff.
The census ads all say that it takes ten minutes to fill out ten questions, but it really takes much less. So go, fill it out and send it in!
* The sentence that starts right before the one that I quoted refers to "three fifths of all other persons" and well, I like to fill out the census as a shot in the face to all of those people who wished that I still counted as three fifths of a person, especially in honor of Confederate History Month.
