ORLANDO, Fla. — A new survey says 84 percent of Americans definitely or probably plan to answer the questions on the 2020 Census.

But the Pew Research Center survey released Friday also says that around 16 percent of Americans express some doubts about responding next spring.

The hesitancy in participating in the head count was higher in black, Hispanic and low-income communities — which all have either been either undercounted or considered hard to count in past censuses.

The Pew survey found no differences between Democrats and Republicans regarding awareness and plans to participate.

The 2020 Census will determine how many congressional seats each state gets and guide the allocation of hundreds of billions of dollars of federal funding.

The survey was conducted online among 6,878 adults, in English and Spanish, last month.
