The Challenges Related to the Census:
How to Count Everyone Once, Only Once, and in the Right Place
1. Reaching Hard to Count Communities
Mapping Hard to Count (HTC) Communities. Those in red are areas that contained varying degrees of uncounted communities in the 2010 Census.
2. Does the Risk of not Participating Outweigh the Risk of Participating?
There are many factors that may lead to an undercount in the Census:

- Many people face barriers to participation, such as people experiencing homelessness, and those speaking languages that the Census online form will not be translated into, such as Hmong, Oromo, and Somali. (Note: Videos and printed materials will also be made available in 59 total languages. Many local community centers, libraries, schools, and nonprofits are also offering other census resources.)
- Despite the fact that the citizenship question will not be included on the 2020 Census, some communities have uncertainty about whether their other Census data could be used against them.
