Among other interesting tidbits about how data was collected for the 2020 census, here is why it is helpful for census takers to be from the community in which they collect data:
As it turns out, the mass mobilization of out-of-state enumerators is not just uncommon, but generally seen as a violation of the spirit of the census. “One of the foundational concepts of a successful door-knocking operation is that census takers will be knowledgeable about the community in which they’re working,” Lowenthal explained. “This is both so they can do a good job, because they’ll have to understand local culture and hopefully the language, but also so that the people who have to open their doors and talk to them have some confidence in them.”
Going door to door is a difficult task. Some connection to the community could help convince people to cooperate. And when cooperation equals higher response rates and more accurate data, local knowledge is good.
As the piece goes on to note, this does not mean that outside census takers could not help. Having more people going to every address could help boost response rates even if the census takers were from a different part of the country.
I wonder how much local knowledge influences the response rates from proxies, other people who can provide basic demographic information when people at the address do not respond:
According to Terri Ann Lowenthal, a former staff director for the House census oversight subcommittee, 22 percent of cases completed by census takers in 2010 were done so using data taken from proxies. And of those cases, roughly a quarter were deemed useless by the Census Bureau. As a result, millions of people get missed while others get counted twice. These inaccuracies tend to be more frequent in urban centers and tribal areas, but also, as I eventually learned, in rural sections of the country.
It is one thing to have the imprimatur of the Census when talking with a proxy; it would seem to be a bonus to also be a local.
More broadly, this is a reminder of how an important data collection process depends in part on local workers. With a little bit of inside knowledge and awareness, the Census can get better data and then that information can effectively serve many.
