# Tabulation Criteria

After analyzes and examinations on coefficient of variation (CV), It is considered that the following criteria must be met for tabulating the individual data of 2011 PHC in terms of statistical reliability:

* If the proportion of unweighted “12 and below” cell values are 25% or more of the total number of cells in a table, this information (table) should not be used.

* After checking the above criterion, weighted (estimated) cell values which are 130 or less, should be used with caution.

And for the building and dwelling data:

* If the proportion of unweighted “250 and below” cell values are 25% or more of the total number of cells in a table, this information (table) should not be used.

* After checking the above criterion, weighted (estimated) cell values which are 1500 or less, should be used with caution.
