The correct answer is: d) All of the above.
Enumerators are provided with training manuals, maps, and schedules to ensure accurate Census data. Training manuals provide enumerators with the information they need to complete their tasks accurately and efficiently. Maps help enumerators find the addresses they need to visit. Schedules help enumerators stay on track and complete their work in a timely manner.
Training manuals typically cover topics such as the Census questionnaire, interviewing techniques, and confidentiality procedures. Maps may be paper maps or digital maps that can be accessed on a smartphone or tablet. Schedules may be paper schedules or electronic schedules that can be accessed on a computer or mobile device.
By providing enumerators with these resources, the Census Bureau helps to ensure that the data collected is accurate and reliable.
