2020 Census Experiment: Extending the Census Environment to the Mailing Materials

Written by:

This experiment attempted to tap into the unique environment surrounding the decennial census through the materials we use to contact households and request self-enumeration.

Specifically, we tested the effect on self-response rates of a wearable nonmonetary insert (i.e., stickers) that promoted the 2020 Census, mailing materials that incorporate messaging developed by the 2020 Census communications campaign, and the addition of an Every Door Direct Mail (EDDM) piece sent on Census Day.

The generalizability of results from this experiment to future censuses has significant limitations. These limitations stem from an error in the sampling program; changes made to the mailing materials, timing of mail, and number of mailings because of the pandemic; and changes to the general environment in which the 2020 Census occurred because of the pandemic.
