Note: These numbers are known not to include approx. 60 CHP who died prior to 1980. Further, an extensive effort was undertaken in 2006 to reclassify those Inactive and Nonactive CHPs who were determined to be deceased. The jump in the numbers of deceased CHPs in 2006 was a result of this effort and not just a bad year to be a CHP.
