Materials related to the 2020 Census evaluation phase are available for coverage measurement and the 2020 Census Evaluations & Experiments (EAE) operation.
Two principal methods are used for coverage measurement in censuses. One method derives coverage estimates from post-enumeration surveys using dual system estimation. The other method is called Demographic Analysis (DA). DA represents a macro-level approach, where population estimates are developed for the census date by aggregating various types of demographic data.
The EAE covers operational assessments that document how well the census was conducted, evaluations that analyze effectiveness, and experiments that identify potential designs to be tested for the next census. In 2020, this program was called the 2020 Census Evaluations and Experiments (EAE) operation, and in 2010 it was referred to as the 2010 Census Program for Evaluations and Experiments (CPEX).
