People are most likely to answer the door for people from within their community. However, members of hard to count communities are often ineligible to work even temporarily as census enumerators without losing their public assistance (SNAP, TANF, Medicaid, or CHIP).
To help recruit census workers from within these hard to count communities, the federal government permits states to opt into a waiver process to waive or disregard the temporary census income from the eligibility limits for certain types of assistance programs. This will ensure that the additional income from the census work does not cause temporary census workers to lose access to federal assistance programs for their families and children. These waivers encourage members of hard-to-count communities to become census enumerators and thus help ensure a fair and complete count.
