The correct answer is: All of the above.
The use of technology in the Census process is increasing, with the introduction of digital data collection, GPS mapping, and online self-enumeration options.
Digital data collection allows the Census Bureau to collect data more efficiently and accurately. For example, in the 2020 Census, the Census Bureau used handheld tablets to collect data from households. This was a significant improvement over the previous method of collecting data, which was by paper questionnaire.
GPS mapping allows the Census Bureau to geocode addresses more accurately. This is important because it allows the Census Bureau to assign each household to a specific geographic location. This information is used to calculate population counts and to draw legislative districts.
Online self-enumeration options allow households to complete the Census questionnaire online. This is a convenient option for many households, and it can help to reduce the time and cost of the Census.
The use of technology in the Census process is a positive development. It allows the Census Bureau to collect data more efficiently, accurately, and conveniently. This is important because the Census is a vital tool for understanding the population of the United States.
