Since 1790, the United States has taken an official headcount to help ensure a government by and for the people. Article I, Section 2 of the United States Constitution mandates this federal census every 10 years. The Census counts every man, woman and child to guarantee that all people are fairly represented in the political process.

Enter the 23rd Census.

In spring 2011, Washington  received its Census 2010 data for redrawing legislative and congressional district boundaries. The new census information indicates that the state’s official 2010 population is just over 6.7 million people — an increase of nearly 1 million residents in 10 years’ time. This official figure and all accompanying redistricting data are being used by the Washington State Redistricting Commission to redraw the boundaries for each of the state’s 49 legislative and now ten congressional districts.
