=================================== FARS National and Puerto Rico Files ----------------------------------- The FARS Files directory structure has been modified and made consistent across all years, beginning with 1975. In each folder, there are two zip files, one in SAS format and one in CSV format. ========================== FARS Auxiliary Files -------------------- The FARS Auxiliary files are datasets that are derived from the standard FARS datasets: 1. Accident -> Acc_Aux 2. Vehicle -> Veh_Aux 3. Person -> Per_Aux These files are joined by the standard key variables. Please read the following document for additional details: http://www-nrd.nhtsa.dot.gov/Pubs/811364.pdf For User Manuals, please go to: ftp://ftp.nhtsa.dot.gov/FARS/FARS-Doc/FARS_Auxiliary_Analytical_User_Manuals.zip For SAS Format Catalog, please go to: ftp://ftp.nhtsa.dot.gov/FARS/Auxiliary_FARS_Files_Formats Updates --------- 6/3/2016: The changes are: - Massachusetts: Case No. 196 – Two occupants were added and some other fields were updated. - Pennsylvania: Updates were made to the following cases 195, 242, 774, 884, 1102, 1110 and 1113 - South Carolina: Case No. 388 – This case was deleted 8/11/2016: Alcohol related files are regenerated. 9/22/2017: Derived Indian Reservation data elements have been added to the Accident level auxiliary file – ACC_AUX.*. The first data year of availability for the following new Indian Reservation related data elements is 2001: BIA – 1 indicates that the crash occurred on Tribal lands. The geographic location data collected in FARS was used in conjunction with spatial data on the Bureau of Indian Affairs (BIA) land boundaries to identify Tribal lands. SPJ_INDIAN – derived from FARS special jurisdiction (SP_JUR=3) element. 1 indicates that the crash occurred on an Indian Reservation. *INDIAN_RES – 1 indicates either BIA=1 or SPJ_INDIAN=1. This provides a more accurate representation of fatal crashes occurring on Tribal lands. *Use the INDIAN_RES data element to obtain the most complete data. ACC_AUX.* datasets can be merged with other FARS datasets by ST_CASE to obtain additional information on the crash. 8/14/2020: The National accident.csv file has been updated for the variable "Longitute" precision from 4-digit to 8-digits. 3/2/2022: 1. Starting from this file release, the FARS file directory structure has been changed beginning 1982. Auxiliary files are zipped separately from the rest of the FARS files. For each year, there are two folders, one for national and one for Puerto Rico. In each folder, there are four zip files - one zip file for Auxiliary SAS files - one zip file for Auxiliary CSV files - one zip file for non-Auxiliary SAS files - one zip file for non-Auxiliary CSV files 2. PER_AUX, VEH_AUX and ACC_AUX files are updated for both National and Puerto Rico 04/03/2023: Added vPICDecode CSV and SAS files. The vPICDecode files are created using NHTSA's vPIC tool and contain the vPIC decode results for cleanly decoded VINs.
