ZIMBABWE ELECTION SUPPORT NETWORK Accuracy Missing Data For each registrant, the 2018 PVR files should contain 14 pieces of information: 1) serial number (unique to the province), 2) surname, 3) forenames, 4) national ID number, 5) gender, 6) date of birth, 7) address, 8) polling station code, 9) polling station name, 10) ward, 11) local authority, 12) constituency, 13) district, and 14) province. The serial number is purely for record keeping and has no intrinsic meaning. The next six (surname, forenames, national ID number, gender, date of birth, and address) serve to identify the registrant while the remaining seven identify where the registrant is assigned to vote. None of this information is missing for any of the 5,683,936 registrants included in the 2018 PVR. Too Young or Too Old Registrants There is one registrant on the 2018 PVR who will not be 18 by 30 July 2018 (national ID number 48173243-V48 with date of birth of 20 September 2000). There are 944 registrants who are 100 years old or older. Potentially Incorrect Date of Birth 18% (1,021,227) of individuals potentially have the wrong date of birth recorded on their official documents. These registrants were born during 13 days of the year (01 January, 02 February, 03 March, 04, April, 05 May, 06 June, 07 July, 08 August, 09 September, 10 October, 11 November, 12 December and 25 December) (see Chart 2.1). The expected percentage of registrants born on these 13 days is 3.5%. Thus, the actual percentage is more than five times the expected percentage. The number of registrants born on these 13 select days is 7.5% only approximately twice the expected percentage. While this problem with wrong dates of birth is the responsibility of the Office of the Registrar and not the ZEC, it makes it more difficult to identify and remove duplicate records. Unclean Data ID numbers fall into 2 categories - those which are 13 characters long (90.3%) and 14 characters long (9.7%). There are two registrants with ID numbers that are 15 rather than 14 characters long: namely 63-1025317-H45 and 63-1190341-G07. This is due to extra spaces at the end of these IDs. ID 631025317-H45 has 101 spaces after the number suggesting a data entry error and the lack of a validation check during data entry or storage.
