data.frame with 1055 observations on the
following 24 variables:
integer record number in the HHS data base

factorwith 29 levels giving the type of breach (e.g., "Theft" vs., "Unauthorized Access/Disclosure", etc.)
factorwith 41 levels coding the location from which the breach occurred (e.g., "Paper", "Laptop", etc.)

Date of the end of the incident or

The data primarily consists of breaches that occurred from 2010 through early 2014 when the extract was taken. However, a few breaches are recorded including 1 from 1997, 8 from 2002-2007, 13 from 2008 and 56 from 2009. The numbers of breaches from 2010 - 2014 are 211, 229, 227, 254 and 56, respectively. (A chi-square test for equality of the counts from 2010 through 2013 is 4.11, which with 3 degrees of freedom has a significance probability of 0.25. Thus, even though the lowest number is the first and the largest count is the last, the apparent trend is not statistically significant under the usual assumption of independent Poisson trials.)
