Ref 1.

September 13, 2009; The Charter for the World's Oldest People Group is as follows:

1. Collect and post demographic data about persons aged 108 and older;

2. Assist in the validation of such data, worldwide, based on three independent source documents needed to prove the claim. This may include accurate translation of documents by our correspondents from the original source language into English. We will also help to perform statistical analysis of the data for publication in scientific/medical journals, according to various demographic criteria.

3. Collect photographs of such persons for posting on the Internet.

As such, the goal of the WOP Group is to obtain a historical list of the entire set of persons aged 110 and older who are validated. (We begin our validation process at age 108 for "candidates").
