PIERRE, S.D.(WNAX)- A delay in delivering 2020 Census numbers to the states could cause problems in meeting deadlines for redistricting.

Senator Jim Bolin of Canton, who is on this years redistricting committee, says a lot will have to be done quickly.

Bolin says they will get some information later this spring.

Bolin says they can start some preliminary work before the official numbers come in.

Bolin also served on the committee that redrew election boundaries in 2011.
