question about civil rights movement in the 1950's

[tunatartare]

I'm taking an online summer class on American History post-1945. Currently we are studying the Civil Rights movement. In trying to do my assigment for this week, I would like to find (1)the number of registered black voters in 1952, and (2)the number of black voters who voted in the 1952 election. I have tried googling different key words on the subject, but have come up empty handed. If any history buffs on here either know this offhand, or know where I can find this information, I would really appreciate it. Thanks.
