The U.S. Census Bureau has rated each census block across the country based on the likelihood of its residents participating in the 2010 census. Those areas deemed “hard to count” will get more of the outreach effort by the Census Bureau. What makes an area hard to count:
“We looked at what we considered 12 variables that are behind what makes a (Census) tract hard to count,” says Steve Jost, associate communications director at the bureau. “Whether or not more people are living in the same housing, whether or not housing has a telephone, the poverty rate, high school graduation rate, linguistic isolation, mobility, unemployment.”
The darker the blue on the map means a higher portion of residents are deemed “hard to count”.
