Merged at MCD Group level.
Because the 1984 precinct definitions differed substantially from those in 1986-1990, and because a common MCD Group structure would have unnecessarily restricted the number of valid groups in the 1986- 1990 data, we defined MCD Groups separately for 1984 and 1986-1990.
ALL YEARS: County 007 - electoral precincts Anderson W1 P1 through W6 P2 have no obvious matches, but CENSPRECs Ward 1 through 6 seem like they might be correct. These were not matched
MATH84SC County 079 - electoral precincts Columbia 1 through 30 have no obvious matches, but CENSPRECs Ward 1 through 34 seem like they might be correct. These were not matched.
Absentee precincts are labeled absentee, but there is also something called "Barrier Free" and in 1990, "Curbside total." Also, there are "challenged ballots."
South Carolina's 1984 electoral data file has one county - 085 - with virtually no common precinct names as the Census file *or* the other three electoral data files (1986-90). County 085 can break into as many as 4 MCDgroups, however. One possible option was to identify County 085 as an 'exception' for PLVDKEY. This technique cost three extra units that could be used in the 1986-90 data. However, the option selected was to use *different* MCDgroup assignments for 1984 and for 1986-90, and then to merge to Census data separately as well.
The 1986-90 merge process used the filenames as they are specified in the programs sheet.
The 1984-only process used sc 84.mcd, sc 84.mge, sc 84.mgl, sc 84.mgs -> PLVDKEY input and output
