BINGHAMTON, N.Y., Sept. 21 (UPI) -- An analysis of historic census figures reveals the death toll in the U.S. Civil War was higher than previously estimated, a historian says.
Many historians agree the 620,000 estimate is flawed, as neither the Union nor the Confederacy kept standardized personnel records.
"There are also huge problems estimating mortality with census data," Hacker said. "You can track the number of people of certain ages from one census to the next, and you can see how many are missing," but people are routinely undercounted, he said.
