"Stats 20" (2005) - without the English/Welsh form (Word 112 pages)

Further documentation

The documents below were produced in December 2003 - although there have been minor changes to the descriptions/labels of a few variables/codes there have been no changes to the variables or the valid codes.

Introduction to the specification for 2005 (3 pages)
List of changes to be made from January 2005 (14 pages)
Full list of "Stats 19" variables and values (2005) (15 pages)
"Stats 19" (2005) - for completion by Police (4 pages)
"Stats 19" (2005) - self-reported accidents (3 pages)
"Stats 21" (2005) ( 21 pages) NB: The following changes have been made since this was produced:

variable 2.9 Vehicle location at time of accident...
the check "IF 1.12 (1st Road Class) = 1 or 2.." should be:
IF 1.12 (1st Road Class) = 1 or 2 THEN 2.9 = 00, 02, 05, 06, 07 or 08
because code 02 (bus lane) is valid (as there is one on part of the M4)

Variable 3.10 Pedestrian Location
the check "IF 3.10 = 01-04..." should be:
IF 3.10 = 01-04 THEN 1.20a (Pedestrian Crossing - Human Control) = 1 or 2 OR 1.20b (Pedestrian Crossing - Physical Facilities) = 1, 4, 5, 7, 8 or 9
because 1.20b code 7 "Footbridge or subway" is valid (it is a type of pedestrian crossing facility, which variable 3.10 codes 01-04 indicate is present).

Variable 2.22 Age of Driver
under the "Comments" heading, the check "If driver age unknown...." should be:
If Driver Age is unknown 2.22 MUST = BLANK (not 00 or 99)
BLANK acceptable if 2.24 (Hit and Run) = 1 or 2 or 2.7 (Manoeuvres) = 2
