Definition
The ability to read and write with understanding in any language. A person is a literate when he can both read and write a simple message in any language or dialect. A person who cannot both read and write a simple message is considered illiterate. Also to be considered as illiterate is that person who is capable of reading only his own name or numbers, as well as persons who can read but not write, or vice versa.
For CIPS, 2004 children aged 0-5 were treated as illiterates by definition even if a few them could read and write.
