These newly published outreach materials from Child360 and NALEO Educational Fundhelp spread the message that all children count in several languages. From The Census Project:

Young children are one of the groups regularly undercounted in the decennial census. That’s why the Leadership Conference on Civil and Human Rights is circulating a series of postcards to help encourage the inclusion of children up to four years of age in the 2020 Census. The cards are a convenient get-out-the-count tool, and come in multiple languages, with English on the front, and SpanishArmenianKoreanVietnameseCantonese and Mandarin on the back.

Everybody Counts! Postcards
