Abstract
This data insight highlights the Transportation
Security Administration (TSA) claims data as an
underused data set that would be particularly useful
to researchers developing statistical models to ana-
lyze claim frequency and severity. Individuals who
have been injured or had items damaged, lost or
stolen may make a claim for losses to the TSA. The
federal government reports information on every
claim from 2002 to 2017 at https://www.dhs.gov/tsa-
claims-data. Information collected includes claim
date and type and site as well as closed claim amount
and disposition (whether it was approved in full,
denied, or settled. We provide summary statistics on
the frequency and the severity of the data for the
years 2003 to 2015. The data set has several unique
features including severity is not truncated (there is
no deductible), there are significant mass points in
the severity data, and the frequency data shows a
high degree of auto correlation if compiled on a
weekly basis, and substantial frequency mass points
at zero for daily data.
