In order to prevent the inadvertent release of potentially identifying information, a number of restrictions have been employed.

  1. Some queries return counts with an asterisk or no counts at all. Asterisks occur when a count is between 1 and 4. The number is also removed from the column and row total.
  2. If a user selects a cohort/sample with less than 100 individuals, then no results are shown.
  3. The query tool returns groupings or categories of data for birth year, death year, age, and location.
