Today marks a rather important day for us at the Census Bureau. The first set of advance letters, mailed to a subset of the Update/Leave households should be delivered today by the US Postal Service throughout the country. We expect that there will be about 9.9 million letters received by households in the update/leave areas.

You’ll remember that these update/leave areas are ones where starting March 1, a census staff member will drop off a paper census form in a plastic bag at each housing unit, after updating our list of housing units.

This decade we’re doing this more than usual in the Gulf Coast areas affected by hurricanes.

Please submit any questions pertaining to this post to ask.census.gov.
