I'm looking for data that would let me estimate how much written language young Chinese at different ages know, in terms of number of characters they can read/write.
Examples of materials that would help answer this question:
- lists of characters that Chinese pupils learn at different grades at school (ideally official lists, if there are any)
- statistics of how many new characters they learn at each grade
- information about how many hours at every grade are dedicated exclusively to learning characters
I'm interested in data from China and from other Chinese-speaking countries.
