The Fatality Analysis Reporting System (FARS) 2021 Final Release - Fatal Motor Vehicle Accidents dataset was compiled from January 1, 2021 to December 31, 2021 by the National Highway Traffic Safety Administration (NHTSA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This geospatial dataset is the accident file from the FARS 2021 Final Release Data. The Final Release Data is published 12-15 months, after the initial release of FARS, and could contain additional fatal accidents due to the delay in police reporting, toxicology reports, etc., along with changes to attribute information for previously reported fatal accidents. This data file contains information about crash characteristics and environmental conditions at the time of the crash. There is one record per crash.

The Fatality Analysis Reporting System (FARS) 2023 Initial Release - Vehicle Information Auxiliary File dataset was compiled from January 1, 2023 to December 31, 2023 by the National Highway Traffic Safety Administration (NHTSA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This file contain elements derived from the FARS datasets to make it easier to extract certain data classifications and topical areas. This file downloaded from the open data catalog is synonymous with what USDOT/NHTSA releases for FARS as the VEH_AUX file. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529024

The Fatality Analysis Reporting System (FARS) 2022 Initial Release - Vehicle Information Auxiliary File dataset was compiled from January 1, 2022 to December 31, 2022 by the National Highway Traffic Safety Administration (NHTSA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This file contain elements derived from the FARS datasets to make it easier to extract certain data classifications and topical areas. This file downloaded from the open data catalog is synonymous with what USDOT/NHTSA releases for FARS as the VEH_AUX file.

The State Traffic Safety Information (STSI) portal is part of the larger Fatality Analysis Reporting System (FARS) Encyclopedia. STSI provides state-by-state traffic safety profiles, including: crash data, lives saved/savable, legislation, economic costs, grant funding, alcohol related crash data, performance measures, and geographic maps of crash data.

This data set shows all fatal crashes and their investigative outcomes from PPD's Accident Investigation Unit (AID) from 1/1/19 to the present. The whole dataset gets refreshed nightly. This means the dataset will show new records the day after the source data has updated. __For those conducting analysis, this dataset by PPD and [OTIS' crash data](https://opendataphilly.org/datasets/vehicular-crashes/) should not be compared, or should be used together cautiously.__ The same crash may show as in different locations between the two datasets since PPD data represent the location of where crashes are initially _reported_ whereas OTIS' crash data involves further investigation to confirm initial reports. If you want to analyze the location of crashes in Philadelphia, use OTIS' dataset. If you want to understand the investigative outcomes of crashes, use the PPD dataset.
