Help us complete this description Edit
Re-upload of the dataset as it is present in the Penn ML Benchmark (https://github.com/EpistasisLab/penn-ml-benchmarks/tree/master/datasets/classification/fars). It's a dataset on traffic accidents, see https://data.world/nhtsa/fars-data. I am not sure of the specific date or aggregation method as it is just a re-upload.
