    The following chart shows the growth of CLDR locale-specific data over time. It does not include the non-locale specific data, nor locale-specific data that is not collected via the Survey Tool. It is thus restricted to data items in /main and /annotations directories. The % values are percent of the current measure of Modern coverage. (That level is notched up each release.)
