Merged at MCD Group level.
There are several electoral precincts of the form A-B where A and B have different MCDGRPs. In county 151 these were left in place. MCDGRP -A gets the electoral precinct information and MCDGRP -B ges nothing which often results in no voting data for that group. The following is a list of the MCDGRPs that recieved a surplus and deficit of electoral information in 1990:
SURPLUS DEFICIT 895 897 899 901 ** 894 903 910 905 896 909 ** and also: 810 807,813 ** in county 129. and also: 116 120 ** in county 17. **also a problem in 1988, 86 and 84.
In three cases a electoral precinct could be easily assigned by a matching keyword to one of two MCDGRPs. In both cases one of the two groups had as yet no associated electoral precincts and so the match was given to that MCDGRP.
The single match to 098 could conceivably have gone to 097, similarly the match to 1059 could have gone to 1060, and the matched pair to 1124 could have gone to 1125.
All other empty MCDGRPs in the Matf ia.log are empty. There are 55 in 1990, 37 in 88, 36 in 86 and ** in 84.
The following electoral precincts were left blank, since each of their component parts has a different MCDGRP. It is possible they were assigned an MCDGRP in the first place due to mistaken handmatching.
For all years: County 129: Rawles-Lyons-Tabor County 151: Center-Sherman
For MATH90IA only: County 151: Swan Lake-Marshall
A number of counties had a new kind of problem - one PLVDKEY precinct matching to two or more Census precincts with *different* MCDGRPs. For the sake of accuracy, all counties in which such problems occurred, no matter how slight, were made exceptions and the PLVDKEY was re-run. The cost was about 400-500 units, with over 1100 still remaining. After the Exceptions Were Incorporated
Many electoral precinct in Iowa seem to be aggregations of CENSPREC. Often the component CENSPRECs have different MCDGRPs, so it was not clear which MCDGRP to assign to the electoral precinct.
In hand matching through county 151 of the 1984 data problematic electoral precincts are followed by potential MCDGRPs.
